You can program this handler to display a more informative error message, log the error to a file or error message in database and/or take remedial action. By Contributor Melonfire | September 8, 2006, 11:46 AM PST RSS Comments Facebook Linkedin Twitter More Email Print Reddit Delicious Digg Pinterest Stumbleupon Google Plus If you've been working with PHP for any length of time, you probably already know what happens when your PHP script turns out to have an error. Typically, the PHP parser will generate a message on the screen — maybe something like Fatal error: Call to undefined function on line 19 — and immediately stop processing the code. This message will scare your customer, who will immediately start yelling on the phone at you to fix it. If you're really unlucky, this phone call will come at 2.14 AM, just when you've begun dreaming about your next vacation to Aruba... Fortunately, there's a solution. PHP comes with built-in tools to let the developer trap script errors and divert them to their own user-defined error handler. You can then program this handler to display a more informat
what happens when you get an error without displaying anything? It’s easy to test, just raise a random error with this code: php ini_set('display_errors', 'Off'); ini_set('log_errors', 1); ini_set('error_reporting', E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED); trigger_error('A random error happened!'); ?> What you will get (most of the time) is a withe web page (if you have a PHP file containing only the previous piece of code). It’s not really helpful to your users, is it? If you get a default error page, it’s also possible that it’s coming from your browser. If that’s the case, you can try to disable the setting ‘friendly error message’ within your browser’s configurations. This should show you the real error page that your browser received. Anyway, that’s where the function set_error_handler() comes in handy when you need to customize the way errors are handled. Things to Note With set_error_handler() We will add a custom ‘error handler’ to the previous code. It will display a simple message to our users when an error happened, but before there are a couple of things to note in the official manual about set_error_handler(). The PHP error handler is bypassed for the error types you specify. This means that the default behaviour won't happen, so you will need to manually specify to log your errors (with the function error_log). You could return FALSE from your custom error handler to 'call' the default PHP error behaviour (like automatically logging errors). You need to stop the script with die() or else the script that raised the error will continue to be executed. If you use 'die(
