Re: Function call stack

If you set_error_handler, then you get automatically line number and filename. Read through: http://www.php.net/manual/en/function.set-error-handler.php (read user comments! there are undocumented things) Then set up your handler like this: $_old_error_handler = set_error_handler("myErrorHandler"); function somefunction(){ #do some stuff trigger_error("Something went wrong, don't know why, sorry", E_USER_ERROR); } function myErrorHandler($level, $message, $file, $line, $context){ #$context contains _ALL_ variabels in scope when error happened echo "D'oh, an error has occurred: $message.\n"; echo "It happened in file $file at line $line and it is a $level-error"; } the most beauty about that is that you can also cover errors you didn't handle (e.g. if fopen triggers a warning or whatever) best regards stefan rusterholz ----- Original Message ----- From: "Lars Torben Wilson" <torben@php.net> To: "Christian Novak" <cnovak@gmx.net> Cc: <php-general@lists.php.net> Sent: Wednesday, January 30, 2002 12:45 PM Subject: Re: [PHP] Function call stack > On Wed, 2002-01-30 at 03:33, Christian Novak wrote: > > Has anyone an idea on how to get information from PHP on the function call > > stack. > > I need the line number and file calling a function for a custom error > > handler. > > This cannot be done in current versions of PHP.
