Check if POST data exists

[Anon]

Hi, quick question.

I'm doing one of these:

foreach ($GLOBALS[HTTP_POST_VARS] as $Key=>$Value) { ... }

to parse some POST data. However, that line will return some messy errors if there is no POST data, and I'd like to catch it.

isset($GLOBALS[HTTP_POST_VARS]);
and isset(HTTP_POST_VARS);
don't seem to work.

Any ideas?

<?PHP

if( !empty( $HTTP_POST_VARS ) )
{
foreach(...)
}

?>
