Create and Delete Cookies with PHP

Create PHP Cookies I

Syntax:

setcookie($name, $value, $expire, $path);

Here, $name specifies the name of cookie, $value specifies the value of cookie, $expire specifies the cookie expiration time and $path specifies the creating path of cookie. The ‘/’ sign is used for creating cookie in current domain.
Example:

<!DOCTYPE html>

<?php
// Creating cookie
   setcookie("TempCookie", "PHPCookie", time()+1*24*60*60,'/') ;
 ?>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
        <title></title>
    </head>
    <body>
        <p>Testing of Cookie Creating </p>
        </br>
        <h3><p>Now retrieve the cookie value </p></h3>
        </br>
        <?php
        // Retrieve the cookie value with $_COOKIE[] function
            echo 'Cookie value is : '.$_COOKIE["TempCookie"];
       ?>
    </body>
</html>

In the example above the expiration time is set to a day (60 sec * 60 min * 24 hours * 1 day).


Create PHP Cookies II (with Isset)

<!DOCTYPE html>
<?php
// Creating cookie
   setcookie("UserTempCookie", "UserCookie", time()+1*24*60*60) ;
 ?>

<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
        <title>Cookie Test</title>
    </head>
    <body>
        <p>Testing of Cookie Creating </p>
        </br>
        <h3><p>Is Cookie value set?  </p></h3>
        </br>
        <?php
            // check, is cookie set or not
        if(isset ($_COOKIE["UserTempCookie"]))
            echo 'Answer is : yes'.' '.'and cookie value is :'.$_COOKIE["UserTempCookie"];
        else
            echo 'Answer : No';
        ?>
    </body>
</html>


Deleting Cookie:
When deleting a cookie you should assure that the expiration date is in the past.
Let’s we have an example, how to delete cookie in PHP.
Example:

<!DOCTYPE html>
<html>
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
        <title>Cookie Test</title>
    </head>
    <body>
        <?php
             setcookie("UserTempCookie","",time()-3600);
             echo 'Cookie deleted successfully';
        ?>
    </body>
</html>
