Any way to enable "display_errors" (PHP) on a page-by-page basis?

Report · Dec 18, 2007

I have just discovered that my host sets 'display_errors' OFF by default. I
have asked them not to do this, but in the meantime, is there any way I can
enable this on the specific page?

A live production site should never have display_errors turned on. It
gives malicious attackers valuable information about your server structure.

It's very easy to turn on the display of errors to debug a particular
script. Just add this at the very top of the page:

<?php ini_set('display_errors', '1'); ?>

It must come before anything else.

Thanks, David.

I'll have to adjust my thinking! 8(

How about adjusting it this way: take code that David suggests, wrap it with an if statement that checks for you or a specified group of users being logged into the site, then you get the error reports, but no one that isn't authorized does.

The better idea on a live site is to write errors to a logfile. With
debug_backtrace() or your own error/exception handler it's even possible
to get a nice backtrace to where the error occured and which function
calls led to it.
