  33. parse_url — Parse a URL and return its components
  34. Description ¶
  35. mixed parse_url ( string $url [, int $component = -1 ] )
  36.  
  37. This function parses a URL and returns an associative array containing any of the various components of the URL that are present.
  38.  
  39. This function is not meant to validate the given URL, it only breaks it up into the above listed parts. Partial URLs are also accepted, parse_url() tries its best to parse them correctly.
  40. Parameters ¶
  41.  
  42. url
  43.  
  44. The URL to parse. Invalid characters are replaced by _.
  45.  
  46. component
  47.  
  48. Specify one of PHP_URL_SCHEME, PHP_URL_HOST, PHP_URL_PORT, PHP_URL_USER, PHP_URL_PASS, PHP_URL_PATH, PHP_URL_QUERY or PHP_URL_FRAGMENT to retrieve just a specific URL component as a string (except when PHP_URL_PORT is given, in which case the return value will be an integer).
  49.  
  50. Return Values ¶
  51.  
  52. On seriously malformed URLs, parse_url() may return FALSE.
  53.  
  54. If the component parameter is omitted, an associative array is returned. At least one element will be present within the array. Potential keys within this array are:
  55.  
  56. scheme - e.g. http
  57. host
  58. port
  59. user
  60. pass
  61. path
  62. query - after the question mark ?
  63. fragment - after the hashmark #
  64.  
  65. If the component parameter is specified, parse_url() returns a string (or an integer, in the case of PHP_URL_PORT) instead of an array. If the requested component doesn't exist within the given URL, NULL will be returned.
  66. Changelog ¶
  67. Version Description
  68. 5.4.7 Fixed host recognition when scheme is omitted and a leading component separator is present.
  69. 5.3.3 Removed the E_WARNING that was emitted when URL parsing failed.
  70. 5.1.2 Added the component parameter.
  71. Examples ¶
  72.  
  73. Example #1 A parse_url() example
  74. <?php
  75. $url = 'http://username:password@hostname:9090/path?arg=value#anchor';

  118. <?php
  119. $url = '//www.example.com/path?googleguy=googley';
  120.  
  121. // Prior to 5.4.7 this would show the path as "//www.example.com/path"
  122. var_dump(parse_url($url));
  123. ?>
  124.  
  125. The above example will output:
  126.  
  127. array(3) {
  128. ["host"]=>
  129. string(15) "www.example.com"
  130. ["path"]=>
  131. string(5) "/path"
  132. ["query"]=>
  133. string(17) "googleguy=googley"
  134. }
  135.  
  136. Notes ¶
  137.  
  138. Note:
  139.  
  140. This function doesn't work with relative URLs.
  141.  
  142. Note:
  143.  
  144. This function is intended specifically for the purpose of parsing URLs and not URIs. However, to comply with PHP's backwards compatibility requirements it makes an exception for the file:// scheme where triple slashes (file:///...) are allowed. For any other scheme this is invalid.

  295. Here's a good way to using parse_url () gets the youtube link.
  296. This function I used in many works:
  297.  
  298. <?php
  299. function youtube($url, $width=560, $height=315, $fullscreen=true)
  300. {
  301. parse_str( parse_url( $url, PHP_URL_QUERY ), $my_array_of_vars );
  302. $youtube= '<iframe allowtransparency="true" scrolling="no" width="'.$width.'" height="'.$height.'" src="//www.youtube.com/embed/'.$my_array_of_vars['v'].'" frameborder="0"'.($fullscreen?' allowfullscreen':NULL).'></iframe>';
  303. return $youtube;
  304. }
  305.  
  306. // show youtube on my page
  307. $url='http://www.youtube.com/watch?v=yvTd6XxgCBE';
  308. youtube($url, 560, 315, true);
  309. ?>
  310.  
  311. parse_url () allocates a unique youtube code and put into iframe link and displayed on your page. The size of the videos choose yourself.
  312.  
  313. Enjoy.

  345. @ solenoid: Your code was very helpful, but it fails when the current URL has no query string (it appends '&' instead of '?' before the query). Below is a fixed version that catches this edge case and corrects it.
  346.  
  347. <?php
  348. function modify_url($mod)
  349. {
  350. $url = "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
  351. $query = explode("&", $_SERVER['QUERY_STRING']);
  352. if (!$_SERVER['QUERY_STRING']) {$queryStart = "?";} else {$queryStart = "&";}
  353. // modify/delete data
  354. foreach($query as $q)
  355. {
  356. list($key, $value) = explode("=", $q);
  357. if(array_key_exists($key, $mod))
  358. {
  359. if($mod[$key])
  360. {
  361. $url = preg_replace('/'.$key.'='.$value.'/', $key.'='.$mod[$key], $url);
  362. }
  363. else
  364. {
  365. $url = preg_replace('/&?'.$key.'='.$value.'/', '', $url);
  366. }
  367. }
  368. }
  369. // add new data
  370. foreach($mod as $key => $value)
  371. {
  372. if($value && !preg_match('/'.$key.'=/', $url))
  373. {
  374. $url .= $queryStart.$key.'='.$value;
  375. }
  376. }

  385. parse_url doesn't works if the protocol doesn't specified. This seems like sandard, even the youtube doesn't gives the protocol name when generates code for embedding which have a look like "//youtube.com/etc".
  386.  
  387. So, to avoid bug, you must always check, whether the provided url has the protocol, and if not (starts with 2 slashes) -- add the "http:" prefix.

  393. At least in php 5.6.x this function does appear to work with relative URLs despite what it says above.
  394.  
  395. Obviously it does not return the scheme or host, but it does return the path and query string and fragment from a relative URL.

  547. Thanks to xellisx for his parse_query function. I used it in one of my projects and it works well. But it has an error. I fixed the error and improved it a little bit. Here is my version of it:
  548.  
  549. <?php
  550. // Originally written by xellisx
  551. function parse_query($var)
  552. {
  553. /**
  554. * Use this function to parse out the query array element from
  555. * the output of parse_url().
  556. */
  557. $var = parse_url($var, PHP_URL_QUERY);
  558. $var = html_entity_decode($var);
  559. $var = explode('&', $var);
  560. $arr = array();
  561.  
  562. foreach($var as $val)
  563. {
  564. $x = explode('=', $val);
  565. $arr[$x[0]] = $x[1];
  566. }
  567. unset($val, $x, $var);
  568. return $arr;
  569. }
  570. ?>
  571.  
  572. At the first line there was parse_query($val), I made it $var. It used to return a null array before this fix.
  573.  
  574. I have added the parse_url line. So now the function will only focus in the query part, not the whole URL. This is useful if something like below is done:
  575. <?php
  576. $my_GET = parse_query($_SERVER['REQUEST_URI']);
  577. ?>

  583. Hello, for some odd reason, parse_url returns the host (ex. example.com) as the path when no scheme is provided in the input url. So I've written a quick function to get the real host:
  584.  
  585. <?php
  586. function getHost($Address) {
  587. $parseUrl = parse_url(trim($Address));
  588. return trim($parseUrl[host] ? $parseUrl[host] : array_shift(explode('/', $parseUrl[path], 2)));
  589. }
  590.  
  591. getHost("example.com"); // Gives example.com
  592. getHost("http://example.com"); // Gives example.com
  593. getHost("www.example.com"); // Gives www.example.com
  594. getHost("http://example.com/xyz"); // Gives example.com
  595. ?>
  596.  
  597. You could try anything! It gives the host (including the subdomain if exists).
  598.  
  599. Hope it helped you.

  632. Yet another URL builder implementation:
  633.  
  634. <?php
  635. function build_url(array $elements)
  636. {
  637. $e = $elements;
  638. return
  639. (isset($e['host']) ? (
  640. (isset($e['scheme']) ? "$e[scheme]://" : '//') .
  641. (isset($e['user']) ? $e['user'] . (isset($e['pass']) ? ":$e[pass]" : '') . '@' : '') .
  642. $e['host'] .
  643. (isset($e['port']) ? ":$e[port]" : '')
  644. ) : '') .
  645. (isset($e['path']) ? $e['path'] : '/') .
  646. (isset($e['query']) ? '?' . (is_array($e['query']) ? http_build_query($e['query'], '', '&') : $e['query']) : '') .
  647. (isset($e['fragment']) ? "#$e[fragment]" : '')
  648. ;
  649. }
  650. ?>
  651.  
  652. For convenience, you can pass $elements['query'] as array.
  653.  
  654. Example:
  655.  
  656. <?php
  657. $elements = [
  658. "host" => "example.com",
  659. "user" => "root",
  660. "pass" => "stupid",
  661. "path" => "/x/y/z",
  662. "query" => [
  663. "a" => "b",
  664. "c" => "d",
  665. ],
  666. ];
  667. echo build_url($elements);
  668. ?>
  669.  
  670. will output

  780. I have coded a function which converts relative URL to absolute URL for a project of mine. Considering I could not find it elsewhere, I figured I would post it here.
  781.  
  782. The following function takes in 2 parameters, the first parameter is the URL you want to convert from relative to absolute, and the second parameter is a sample of the absolute URL.
  783.  
  784. Currently it does not resolve '../' in the URL, only because I do not need it. Most webservers will resolve this for you. If you want it to resolve the '../' in the path, it just takes minor modifications.
  785.  
  786. <?php
  787.  
  788. function relativeToAbsolute($inurl, $absolute) {
  789. // Get all parts so not getting them multiple times :)
  790. $absolute_parts = parse_url($absolute);
  791. // Test if URL is already absolute (contains host, or begins with '/')
  792. if ( (strpos($inurl, $absolute_parts['host']) == false) ) {
  793. // Define $tmpurlprefix to prevent errors below
  794. $tmpurlprefix = "";
  795. // Formulate URL prefix (SCHEME)
  796. if (!(empty($absolute_parts['scheme']))) {
  797. // Add scheme to tmpurlprefix
  798. $tmpurlprefix .= $absolute_parts['scheme'] . "://";
  799. }
  800. // Formulate URL prefix (USER, PASS)
  801. if ((!(empty($absolute_parts['user']))) and (!(empty($absolute_parts['pass'])))) {
  802. // Add user:port to tmpurlprefix
  803. $tmpurlprefix .= $absolute_parts['user'] . ":" . $absolute_parts['pass'] . "@";
  804. }
  805. // Formulate URL prefix (HOST, PORT)
  806. if (!(empty($absolute_parts['host']))) {

  881. This function will attempt to parse relative URLs but relaying on it can produce unexpected behavior that can cause some hard to track bugs. (The following results are obtained from PHP 5.5.19)
  882.  
  883. Attempting to parse a url like this
  884. http://example.com/entities/GOA:98/?search=8989157d1f22
  885. Correctly produces
  886. <?php
  887. array (
  888. 'scheme' => 'http',
  889. 'host' => 'example.com',
  890. 'path' => '/entities/GOA:98/',
  891. 'query' => 'search=8989157d1f22',
  892. );
  893. ?>
  894.  
  895. However, Attempting to parse the relative URL
  896. entities/GOA:98/?search=8989157d1f22
  897. <?php
  898. array (
  899. 'host' => 'entities',
  900. 'port' => 98,
  901. 'path' => '/GOA:98/',
  902. 'query' => 'search=8989157d1f22',
  903. )
  904. ?>
  905. If I change :98 to :A98 parse_url parses the URL correctly as
  906. <?php
  907. array (
  908. 'path' => 'entities/GOA:A98/',
  909. 'query' => 'search=8989157d1f22',
  910. )
  911. ?>
  912. Bottom line, Avoid using parse_url for relative urls unless you have tested the expected input and you know parse_url will handle them well.

  918. UTF-8 aware parse_url() replacement.
  919.  
  920. I've realized that even though UTF-8 characters are not allowed in URL's, I have to work with a lot of them and parse_url() will break.
  921.  
  922. Based largely on the work of "mallluhuct at gmail dot com", I added parse_url() compatible "named values" which makes the array values a lot easier to work with (instead of just numbers). I also implemented detection of port, username/password and a back-reference to better detect URL's like this: //en.wikipedia.com
  923. ... which, although is technically an invalid URL, it's used extensively on sites like wikipedia in the href of anchor tags where it's valid in browsers (one of the types of URL's you have to support when crawling pages). This will be accurately detected as the host name instead of "path" as in all other examples.
  924.  
  925. I will submit my complete function (instead of just the RegExp) which is an almost "drop-in" replacement for parse_url(). It returns a cleaned up array (or false) with values compatible with parse_url(). I could have told the preg_match() not to store the unused extra values, but it would complicate the RegExp and make it more difficult to read, understand and extend. The key to detecting UTF-8 characters is the use of the "u" parameter in preg_match().
  926.  
  927. <?php
  928. function parse_utf8_url($url)
  929. {
  930. static $keys = array('scheme'=>0,'user'=>0,'pass'=>0,'host'=>0,'port'=>0,'path'=>0,'query'=>0,'fragment'=>0);
  931. if (is_string($url) && preg_match(
  932. '~^((?P<scheme>[^:/?#]+):(//))?((\\3|//)?(?:(?P<user>[^:]+):(?P<pass>[^@]+)@)?(?P<host>[^/?:#]*))(:(?P<port>\\d+))?' .
  933. '(?P<path>[^?#]*)(\\?(?P<query>[^#]*))?(#(?P<fragment>.*))?~u', $url, $matches))
  934. {
  935. foreach ($matches as $key => $value)
  936. if (!isset($keys[$key]) || empty($value))
  937. unset($matches[$key]);
  938. return $matches;
  939. }
  940. return false;
  941. }
  942. ?>
  943.  
  944. UTF-8 URL's can/should be "normalized" after extraction with this function.

  1016. Many times parse_url return nothing when domain is google.com only for example.
  1017.  
  1018. Now, google.com, or google.co.uk will return the same.

  1340. $r .= "(?:\?(?P<arg>[\w=&]+))?";
  1341. $r .= "(?:#(?P<anchor>\w+))?";
  1342. $r = "!$r!"; // Delimiters
  1343.  
  1344. preg_match ( $r, $url, $out );
  1345.  
  1346. return $out;
  1347. }
  1348. print_r ( parseUrl ( 'me:[email protected]:29000/pear/validate.html?happy=me&sad=you#url' ) );
  1349. ?>
  1350.  
  1351. This returns:
  1352. Array
  1353. (
  1354. [0] => me:[email protected]:29000/pear/validate.html?happy=me&sad=you#url
  1355. [scheme] =>
  1356. [1] =>
  1357. [login] => me
  1358. [2] => me
  1359. [pass] => you
  1360. [3] => you
  1361. [host] => sub.site.org
  1362. [4] => sub.site.org
  1363. [subdomain] => sub
  1364. [5] => sub
  1365. [domain] => site.org
  1366. [6] => site.org
  1367. [extension] => org
  1368. [7] => org
  1369. [port] => 29000
  1370. [8] => 29000
  1371. [path] => /pear/validate.html
  1372. [9] => /pear/validate.html
  1373. [file] => validate.html
  1374. [10] => validate.html
  1375. [arg] => happy=me&sad=you
  1376. [11] => happy=me&sad=you
  1377. [anchor] => url
  1378. [12] => url
  1379. )
  1380.  
  1381. So both named and numbered array keys are possible.
  1382.  
  1383. It's quite advanced, but I think it works in any case... Let me know if it doesn't...

  1389. Note that older versions of PHP (e.g., 4.1) returned an blank string as the path for URLs without any path, such as http://www.php.net
  1390.  
  1391. However more recent versions of PHP (e.g., 4.4.7) don't set the path element in the array, so old code will get a PHP warning about an undefined index.

  1468. Here's a function which implements resolving a relative URL according to RFC 2396 section 5.2. No doubt there are more efficient implementations, but this one tries to remain close to the standard for clarity. It relies on a function called "unparse_url" to implement section 7, left as an exercise for the reader (or you can substitute the "glue_url" function posted earlier).

  1537. Note that if you pass this function a url without a scheme (www.php.net, as opposed to http://www.php.net), the function will incorrectly parse the results. In my test case it returned the domain under the ['path'] element and nothing in the ['host'] element.

  1543. It seems the host-part strips off the last [:port] off the end of the hostname
  1544.  
  1545. When something is wrong in the actual request, this proves to be the wrong way to do things.
  1546.  
  1547. It would be better to not strip off the [:port], but to keep the string *before* the first [:port] as the hostname.
  1548.  
  1549. Problem with (maybe malformed) provided HTTP_HOST
  1550. hostname:443:443
  1551. that resolved in
  1552. 'host' => 'hostname:443'
  1553.  
  1554. Which gave me problems.

  1707. For those of you sending URLs in HTML emails with a redirect address in the query string, note that Hotmail unescapes / and : characters in the query string. So that breaks the parse_url() function call. Take this as an example:
  1708. href="http://example.com/redirect?url=http%3A%2F%2Fplanio.com"
  1709. Hotmail will transform it to this:
  1710. href="http://example.com/redirect?url=http://planio.com"
  1711.  
  1712. The solution is to be preventive before the call to parse_url():
  1713. <?php
  1714. $q_index = strpos($uri, '?');
  1715. if ($q_index !== FALSE &&
  1716. (strpos($uri, ':', $q_index) !== FALSE || strpos($uri, '/', $q_index) !== FALSE)) {
  1717. $begin = substr($uri, 0, $q_index);
  1718. $end = substr($uri, $q_index, strlen($uri)-$q_index);
  1719. $end = str_replace('/', '%2F', $end);
  1720. $end = str_replace(':', '%3A', $end);

  1938.  
  1939. $p = parse_url ( 'http://domain.tld/tcp://domain2.tld/dir/file' ) ;
  1940.  
  1941. $d2 = parse_url ( $p['path'] ) ;
  1942.  
  1943. echo $d2 ; // returns '/dir/file'
  1944.  
  1945. ?>
  1946.  
  1947. Of course my example is very specific, as URL is not really correct. But using parse_url was a great trick to split URL easily (without using regular expressions).
  1948.  
  1949. Unfortunately under PHP 5.2.0-8 (+etch10), parse_url will fail as it does not accept the slash (/) at the beginning of URL.
  1950.  
  1951. Here is a possible patch :
  1952.  
  1953. <?php
  1954.  
  1955. $p = parse_url ( 'http://domain.tld/tcp://domain2.tld/dir/file' ) ;
  1956.  
  1957. $d2 = parse_url ( substr ( $p['path'] , 1 ) ) ;
  1958.  
  1959. echo $d2 ; // returns '/dir/file'
  1960.  
  1961. ?>
  1962.  
  1963. However this last code is not optimized at all, and should be replaced by a regular expression to split URL (so that parse_url would be no longer used).
  1964.  
  1965. So you should use parse_url very carefully, and verify that you pass only standard URLs...

  2074. Another shot at trying to find a better parser. I noticed that the laulibrius/theoriginalmarksimpson functions didn't quite handle the URL for the page they were displayed on. For my mirror, ca3, this is
  2075. http://ca3.php.net/manual/en/function.parse-url.php
  2076.  
  2077. Run it through the function and it parses to
  2078. scheme => http
  2079. login =>
  2080. pass =>
  2081. host => ca3.php.net
  2082. ip =>
  2083. subdomain => ca3
  2084. domain => php.
  2085. extension => net
  2086. port =>
  2087. path => /manual/en/function.parse
  2088. file => function.parse
  2089. that is, the file name gets a bit mangled
  2090.  
  2091. Rather than tweak the function's regular expression yet again, I opted to adapt a RegExp that served me well in Javascript:
  2092.  
  2093. function j_parseUrl($url) {
  2094. $r = "(?:([a-z0-9+-._]+)://)?";
  2095. $r .= "(?:";
  2096. $r .= "(?:((?:[a-z0-9-._~!$&'()*+,;=:]|%[0-9a-f]{2})*)@)?";
  2097. $r .= "((?:[a-z0-9-._~!$&'()*+,;=]|%[0-9a-f]{2})*)";
  2098. $r .= "(?::(\d*))?";
  2099. $r .= "(/(?:[a-z0-9-._~!$&'()*+,;=:@/]|%[0-9a-f]{2})*)?";
  2100. $r .= "|";
  2101. $r .= "(/?";
  2102. $r .= "(?:[a-z0-9-._~!$&'()*+,;=:@]|%[0-9a-f]{2})+";
  2103. $r .= "(?:[a-z0-9-._~!$&'()*+,;=:@\/]|%[0-9a-f]{2})*";
  2104. $r .= ")?";
  2105. $r .= ")";
  2106. $r .= "(?:\?((?:[a-z0-9-._~!$&'()*+,;=:\/?@]|%[0-9a-f]{2})*))?";
  2107. $r .= "(?:#((?:[a-z0-9-._~!$&'()*+,;=:\/?@]|%[0-9a-f]{2})*))?";
  2108. preg_match("`$r`i", $url, $match);
  2109. $parts = array(
  2110. "scheme"=>'',
  2111. "userinfo"=>'',
  2112. "authority"=>'',
  2113. "host"=> '',
  2114. "port"=>'',
  2115. "path"=>'',
  2116. "query"=>'',
  2117. "fragment"=>'');
  2118. switch (count ($match)) {
  2119. case 9: $parts['fragment'] = $match[8];
  2120. case 8: $parts['query'] = $match[7];
  2121. case 7: $parts['path'] = $match[6];
  2122. case 6: $parts['path'] = $match[5] . $parts['path'];
  2123. case 5: $parts['port'] = $match[4];
  2124. case 4: $parts['host'] = $match[3];
  2125. case 3: $parts['userinfo'] = $match[2];
  2126. case 2: $parts['scheme'] = $match[1];
  2127. }
  2128. $parts['authority'] = ($parts['userinfo']?$parts['userinfo']."@":"").
  2129. $parts['host'].
  2130. ($parts['port']?":".$parts['port']:"");
  2131. return $parts;
  2132. }
  2133.  
  2134. This function, when fed "http://ca3.php.net/manual/en/function.parse-url.php", returns
  2135. scheme => http
  2136. userinfo =>
  2137. authority => ca3.php.net
  2138. host => ca3.php.net
  2139. port =>
  2140. path => /manual/en/function.parse-url.php
  2141. query =>
  2142. fragment =>
  2143. which is somewhat closer to my needs.
  2144.  
  2145. But everything should be tested against the two examples provided by RFC3986,
  2146.  
  2147. /* line too long for this site's commnet handler */
  2148. "foo://username:[email protected]:8042".
  2149. "/over/there/index.dtb;type=animal?name=ferret#nose"
  2150. and
  2151. "urn:example:animal:ferret:nose"
  2152.  
  2153. Here the native function parse_url() performs admirably on that "urn:" example. Mine fails to pick out the path ("example:animal:ferret:nose") and the laulibrius/theoriginalmarksimpson function can't decipher anything there. On the "foo:" example, both my function and parse_url() get it right, while the other examples on this page don't.
  2154.  
  2155. The laulibrius/theoriginalmarksimpson function delivers
  2156. scheme => foo
  2157. login => username
  2158. pass => password
  2159. host => example.com
  2160. ip =>
  2161. subdomain =>
  2162. domain => example.
  2163. extension => com
  2164. port => 8042
  2165. path => /over/there/index.dtb
  2166. file => index.dtb
  2167.  
  2168. As you can see, the query string ("name=ferret") and fragment ("nose") have dropped off, as well as the parameter ("type=animal").
