first code


<?php

$filename = 'click_count.txt';
$handle = fopen($filename, 'r');
$hits = trim(fgets($handle)) + 1;
fclose($handle);

$handle = fopen($filename, 'w');
fwrite($handle, $hits);
fclose($handle);

// Uncomment the next line (remove //) to display the number of hits on your page.
//echo $hits;

?>


second code

<?php

$click_value = '0.001'; //Amount in dollars that each click is worth

function increment_clicks()
{
    //Get current click count
	$clicks = ((file_exists('click_count.txt')) ? file_get_contents('click_count.txt') : 0);

    //Add current click to count
    $clicks++;

    //Save new value to file
    $file = fopen('click_count.txt', 'w');
    fwrite($file, $clicks);
    fclose($file);
}

function get_click_amount()
{
    global $click_value;

    //Get current click count
	$clicks = ((file_exists('click_count.txt')) ? file_get_contents('click_count.txt') : 0);

    //Return value of all clicks based on $click_value, formatted to 2 decimal places
    return number_format($clicks * $click_value, 3);
}

if (isset($_GET['sa']))
{
    //Search button was clicked, increment count
    increment_clicks();
}

$click_amount = get_click_amount();
?>
