Re: variable ?

Try this , assuming you're using POST (you can change to GET) : foreach ($HTTP_POST_VARS as $name => $value) { if (!empty($value)) { $full_vars[$name] = $value; } else { $empty_vars[$name] = $values; } } Which creates two arrays, to print them out you could do let's say : foreach ($full_vars as $name => $value) { print "<br>$name is $value"; } foreach ($empty_vars as $name => $value) { print "<br>$name is empty"; } Regards, Philip --.sig [ Want to write Good code?
