PHP Custom Error Page

Everyone says that “Enabling errors to be displayed” on an active site is bad (due to some security issues).

Now we must consider two cases:

  • Site is in debug mode
  • Site is not in debug mode

Now, for case No. 1:

We want to see errors. How?

ini_set('error_reporting', E_ALL);
ini_set('display_errors', 1);

There is nothing easier. We can also set up an error handler for all errors except Parse and Fatal.

Instead, if case # 2:

We would like to be able to deactivate messages:

ini_set('error_reporting', 0);
ini_set('display_errors', 0);
