How to get the name of $_POST variables.

[Anon]

I wanted to know if there is any way of getting the names of $POST variables once they have been passed.
What I would like to do is set up a foreach loop to go through all of the $POST variables and get the names of the ones that have values that aren't blank.

I can't predict the names of the $_POST variables coming in because they are dynamically created on the form page by php and the database.

Thanks,
Blair

<?
foreach ($_POST as $key => $value) {
if ($value) {echo "$key = $value<br>";}
}
?>

This print out all name/value pairs but will skip the ones with blank values.
