Question

Is it possible to trigger a call to a function as soon as any PHP script’s execution is started ?

e.g.

<?php

Include 'a.php';
Include 'b.php';

?>

So what I want to achieve is as soon as a.php is included a call should be triggered to a function.

There should be something like register_shut_down but this function is executed at script shut down time.

Yes this is possible, using a line in your .htaccess file:

php_value auto_prepend_file "prepended.php"

Or inside you php.ini ofcourse, but I’d not recommend it if you host multiple websites on the same server.
