Problem with get_defined_vars() is that it contains everything,
including server and environment vars, and there's no easy way to
keep just the user-defined vars part of the array created by
get_defined_vars.
Monty
foreach ( get_defined_vars() as $key = $val ) {
if ( ! preg_match (
/_POST|_GET|_COOKIE|_SERVER|_ENV|_FILES|_REQUEST|_SESSION/, $key )
) { $user_defined[$key] = $val;
}
}
U, or even, possibly, if no user variable names begin with _
if ($key{0}!='_')
Cheers!

That won't 'strip out' all the non-user defined vars...ones like
HTTP_POST_VARS

From: Steve Douville [EMAIL PROTECTED] ? $a = yes; $b = no; ? Is there a variable that I can call that will return an array with any variables I have set? I'd want to call it and then parse and display current values of, in this case, a and b. Hope that makes sense.

Re: [PHP] Variables - Help
Difficult to tell exactly what your problem is but to disassociate a varaible name to its place in memory you use, unset($varname); -Kevin - Original Message - From: Beauford.2002 [EMAIL PROTECTED] To: PHP General [EMAIL PROTECTED] Sent: Tuesday, December 17, 2002 1:29 PM Subject: [PHP] Variables - Help Hi, I have a webpage where users input information. This gets sent to a PHP page to use this input. The first time the user inputs information it works correctly, but the second, third, forth, etc. times does not. It appears the information from the first time is still stored in the variables I am using in PHP. I have tried setting them all back to zero, but this does not work. So how do I reset all the variables so that the new information is contained in them when the user adds more information.
