What is best practice when setting error reporting on development and production applications? At the moment I have the following:
// development
error_reporting(E_ALL);
// production
ini_set('display_errors', 0);
ini_set('log_errors', 1);
error_reporting(E_ERROR | E_WARNING | E_PARSE);
622
error_reporting(E_ALL); error_reporting(-1); ini_set('error_reporting', E_ALL); All of the above lines serve the same purpose i.e. show all the errors. E_ALL is the most widely used function among all others by developers to display error messages as it is more comprehensible and intelligible.
The error reporting function is a built-in PHP function that allows developers to control which and how many errors will be shown in the application. Remember, the PHP ini configuration has an error_reporting directive that will be set by this function during runtime. error_reporting(0);
How many error levels are available in PHP? There are a whopping 16 error levels in PHP 5. These errors represent the category and sometimes severity of an error in PHP.
The error_reporting() function specifies which errors are reported. PHP has many levels of errors, and using this function sets that level for the current script.
Quoting the php-production.ini that should have come bundled with your PHP:
; PHP comes packaged with two INI files. One that is recommended to be used ; in production environments and one that is recommended to be used in ; development environments. ; php.ini-production contains settings which hold security, performance and ; best practices at its core. But please be aware, these settings may break ; compatibility with older or less security conscience applications. We ; recommending using the production ini in production and testing environments.

; display_errors ; Default Value: On ; Development Value: On ; Production Value: Off ; display_startup_errors ; Default Value: Off ; Development Value: On ; Production Value: Off ; error_reporting ; Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED ; Development Value: E_ALL ; Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT ; html_errors ; Default Value: On ; Development Value: On ; Production value: On ; log_errors ; Default Value: Off ; Development Value: On ; Production Value: On
Since you asked for best practise, I suggest you go with that.
