I find often myself wanting to append a variable to an unknown url. The problem is that you don't know if you should append the var with ? or with &. Do you think it would be useful to have a builtin function that would do this automatically?
example code as I do it actually:
<?php
$foo = mt_rand();
$separator = (ereg('?', $_SERVER['HTTP_REFERER'])) ? '&' : '?';
$url = $_SERVER['HTTP_REFERER'].$separator.'foo='.$foo;
?>
example code with the new version: <?php $foo = mt_rand(); $url = urlappendvar($_SERVER['HTTP_REFERER'], 'foo', $foo); ?>
I use it quite frequently so I thought it could be useful to have such functionality builtin.
What do you think?
