RE: [PHP] Getting Variables

To loop through all of the POST or GET variables do either on or the other (depending on whether your form got or posted). while (list($name,$value) = each($HTTP_POST_VARS)) { echo "$name => $value<BR>\n"; } while (list($name,$value) = each($HTTP_GET_VARS)) { echo "$name => $value<BR>\n"; } In PHP4 you can do the slightly cleaner foreach ($HTTP_POST_VARS as $name => $value) { echo "$name => $value<BR>\n"; } -----Original Message----- From: Jeroen Geusebroek To: php-general@lists.php.net Sent: 29/08/00 7:34 AM Subject: [PHP] Getting Variables Hi there, I have a form which has a lot of values; how can i check in PHP which values have been set without first knowing the name? Normaly you would do: if($a) { echo("blabla"); } But in this case i don't know the name of the variable. Any advice?
