Disable reporting all errors with error_reporting

Question

Is it acceptable to use

error_reporting(0);

to disable reporting of any kind of error (for production)?

Answer 1

That is absolutely valid: see the list of error_reporting below:

<?php

// Turn off all error reporting
error_reporting(0);

// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);

// Reporting E_NOTICE can be good too (to report uninitialized
// variables or catch variable name misspellings ...)
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);

// Report all errors except E_NOTICE
// This is the default value set in php.ini
error_reporting(E_ALL ^ E_NOTICE);

// Report all PHP errors (see changelog)
error_reporting(E_ALL);

// Report all PHP errors
error_reporting(-1);

// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);

?>

Answer 2

You should have error reporting on so you can debug any issues on your production servers.

To prevent users from seeing errors, just disable displaying of errors:

ini_set("display_errors", 0);
