I originally sent this to the general list with no replies. As I'm it concerns writing to the Windows event log, I thought I'd try my luck on this list. I'm running PHP 5.1 on IIS. My dev environment is all local on my machine. My php.ini has the following error reporting settings: error_reporting = E_ALL display_errors = Off display_startup_errors = Off log_errors = On log_errors_max_len = 1024 ignore_repeated_errors = Off ignore_repeated_source = Off report_memleaks = On track_errors = Off error_log = syslog To test, I've written a little script that divides by 0. When I run the script from the command line, I get entries in my Event Log as expected, but if I load the page into my browser (Firefox), no error is reported in the Event Log. I've checked http://www.php.net/manual/en/ref.errorfunc.php but can't find anything there. I figure I must be missing something pretty obvious but not sure what it is. The script and logged error from the command line are below. Thanks for any help. script: <html> <title><head></head></title> <body> <?php $a = 5; $b = 0; $c = $a / $b; echo $c; ?> </body> </html> logged error from command line: The description for Event ID ( 2 ) in Source ( PHP-5.1.2 ) cannot be found. The local computer may not have the necessary registry information or message DLL files to display messages from a remote computer. You may be able to use the /AUXSOURCE= flag to retrieve this description; see Help and Support for details. The following information is part of the event: php[2132], PHP Warning: Division by zero in C:\Inetpub\wwwroot\PHP\Testing\error.php on line 11.
