PHP Native Error Logging - Extend / Show More Info?

Varius

Hello,

I was wondering if it's possible to extend the PHP native error_reporting/error_logging so that it could show more information.

Sometimes, I see in my error log, errors from an include file. These are cases which happens rarely, not consistently, and I would like to be able to know which PHP script called the function in that case where it hit an error.

basically, I'd like to know if it's possible to do this or other customizations to show additional information globally on PHP's error_reporting, as opposed to modifying each place in the code to check for certain circumstances and call the error_log() function manually.

Thanks,

NogDog

I'm not sure if there's anything in the PHP configuration, but you can create a custom error-handler to extend the reporting via [man]set_error_handler/man. You can have your custom function then use [man]debug_backtrace/man to get more info about the call stack and other useful info. (Note that not all error types can be processed this way, see the notes in the [man]set_error_handler[/man] page.)

You can indeed replace PHP's error logging mechanism with your own using [man]set_error_handler/man (e.g. perhaps using auto_prepend_file to automatically load it for every script - you could even define this directive in a .htaccess file in a subdirectory so that only a specific set of PHP files will use it).

Aren't the file name and line number already in the standard PHP error output?

EDIT: Crap, stale tabs got me again. One of these days I will demand that we get a "new-post-while-you-were-replying" feature such as one even ancient versions of phpBB offer.

Thanks for the replies guys, set_error_handler seems to be the way to go 🙂

brad: as for it already containing filename/line number, it contains the name of my included file, I'd like to know which parent file hit the error since many of them include that file and the error is "intermittent" and not a consistent error.

Thanks for the help guys!
