Or why not:
$lookingfor = 'somebutton';
if (isset($_REQUEST[{$lookingfor . '_x'}])) {
print "Found it, a button named $lookingfor was clicked";
}
Or something, I think this is what you mean? Whatever the
problem, there will be a solution ... don't stress :) But
regarding the problem here, I don't get what you mean. How
familiar are you with arrays? Anyway, as Chris stated, the
name/value will be available in the appropriate autoglobal
which will be $_POST or $_GET, and/or $_REQUEST.

It's as of PHP 4.2.0 that the default value of the
register_globals directive went from on to off. It is
this directive that pollutes your script with these
variables and it's recommended to not use them and
leave this deprecated directive off. Now what happened
in PHP 4.1.0 was the introduction of autoglobals but
this is all described in various places in the manual
and here's such a place that links to others:

May as well read this too:

Where have you been, hibernating? :)
