Catch warnings

Hi, i´m writting a php program that parses and saves some xml files on a server. The problem is that i want to catch warnings so as to be able to store them in a variable, but not to be put directly on client´s browser. I got the following code, but i cannot get it working: //-------------------------------------------------------- $old_track = ini_set('track_errors', '1'); if (!@somefunction()) { echo $php_errormsg, "\n"; } ini_set('track_errors', $old_track); //-------------------------------------------------------- When i execute the cgi, the $php_errormsg variable is always empty, even when there are errors. Any ideas? Thanks in advance, Mariano Guadagnini -- No virus found in this outgoing message. Checked by AVG Free Edition. Version: 7.1.362 / Virus Database: 267.13.1/169 - Release Date: 15/11/2005
