Looping Through $_POST array

Hi everyone,

Is there a way to loop through a $_POST array and extract out the names of the elements / form fields only --- as opposed to the field values?

For example:

foreach($_POST as $element)
{
$formfieldname = $element[fieldname];
}

Thanks,

If you want only the element names use array_keys on $_POST. Alternately you can get both keys and values using foreach like this

foreach ($_POST as $key => $value)

This will work. Thanks!
