The sort of method that I used was:
PHP Code:
<?php
if (!isset($_GET['foo']))
{
die("No parameter");
}
$tok = explode("_", $_GET['foo']);
if ($tok[0] == "param1")
{
// ...
}
?>
... and from that, $tok would contain the various components of the paramater if sent like this:
PHP Code:
ob = requestURL("http://localhost/example.php?foo=param1_param2_param3");
But this seems like a fairly crude workaround.
