I have a little script here that counts clicks when link is clicked and stores it in .txt file, but it works fine when I have only "click=yes" under href. But I can't make it to track clicks when I have link to external site.
Here is my code:
<?php
if(!file_exists('counter.txt')){
file_put_contents('counter.txt', '0');
}
if($_GET['click'] == 'yes'){
file_put_contents('counter.txt', ((int) file_get_contents('counter.txt')) + 1);
header('Location: ' . $_SERVER['SCRIPT_NAME']);
die;
}
?>

</head>
<body>
<h1><?php echo file_get_contents('counter.txt'); ?></h1>
<a href="http://www.google.com?click=yes" target="new">clickMe</a>
</body>
</html>
My guess is it has to do something with header('Location: ' . $_SERVER['SCRIPT_NAME']); but I can't figure it out so I could really use some help.
And is it somehow possible to have multiple links save to the same file, and when I show it on website it's sorted from largest number to smallest? I have an idea how to do it with MySQL database but I can't use it at place where this will be implemented.
Thanks in advance! Cheers!
