There is no such function. Usually the person asking it is doing something very newbie-ish, and very wrong. I know, cuz I was that person, many many years ago. :-) I think what I needed that time was "variable variables"... The other thing that tends to bring up this question is somebody trying to write a custom error handler, not knowing about http://php.net/trigger_error and friends. Though that only gets you the line number and filename where the error occured, not a specific variable name. If for some reason one *NEEDS* to have "names" and variables and to know what a variable's "name" is, you *probably* want to use an associative array and use the "keys" as your names. Hopefully this is helpful to the Original Poster, or somebody some day. PS It's true that your variable could/would/should appear in debug_backtrace, but how would you pick it out from all the other variables that would appear in your debug_backtrace? For that matter, it's in $_GLOBALS, but how would you pick it out? You could print out all variables that were equal to your variable, and have a list of candidates... <?php $x = 5; $y = 3; $z = 5; while (list($k, $v) = each($GLOBALS)){ if ($v === $x) echo "$k might be your variable...<br />\n"; } ?> -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
