Disabling Strict Standards Errors in WordPress 3.7 with PHP 5.4

Question

I am trying to disable STRICT Error reporting in WordPress 3.7 via my php.ini file after updating my computer to OS X 10.9. I am running PHP Version 5.4.17, the one that ships with Mavericks.

In my wp-config.php file, I have enabled define('WP_DEBUG', true); which was on a working fine before upgrading my OS and as a result, PHP.

In the php.ini file, I have tried setting error_reporting to:

error_reporting = E_ALL

or

error_reporting = E_ALL & ~E_STRICT

or

error_reporting = E_ALL & ~E_DEPRECATED

even

error_reporting = 0

But the errors still appear.

display_errors is set to Off:

display_errors = Off

After each change to the file, I am restarting apache and httpd with these two commands:

httpd -k restart
apachectl restart

The php.ini file I am editing is the same one being pointed to in phpinfo() AND just to make sure changes are going through, I have been editing the error_prepend_string value:

error_prepend_string = "<span style='color: #ff0000'>ERROR: "

and those changes are coming through in the error.

Any thoughts on how to debug this would be much appreciated.

Solution

In Wordpress 3.7, the function wp_debug_mode (defined in wp-includes/load.php, and called from wp-setings.php) sets error_reporting( E_ALL ).

Since wp-settings.php is itself loaded at the end of wp-config.php, you cannot change this setting from wp-config.php (or rather, you can, but it will be overridden).

A solution is to create a "Must Use plugin", that is to say a .php file located in the /wp-content/mu-plugins/ folder containing :

<?php
if (WP_DEBUG && WP_DEBUG_DISPLAY) 
{
   ini_set('error_reporting', E_ALL & ~E_STRICT & ~E_DEPRECATED);
}

This works partially, because some error happen before functions.php gets loaded. +1 for the idea however :)

I didn't see any errors in my (limited) testing, though I suppose it can happen when loading plugins. Looking at Wordpress load order, maybe a solution is to create a very simple plugin to set error_reporting, making sure it is loaded before any other plugin (by default they are loaded in alphabetical order).

For best results, use the solution provided by adelval, but put it in a .php file such as: /wp-content/mu-plugins/errorreporting.php. "mu" stands for "must-use" and will be loaded before the theme and plugins, but after the error reporting has been set. You don't have to activate it, either, since they are "must-use".

Thanks @Alexandre for the edit, it improves the answer by incorporating the comment by RadGH

This didnt help me either as the deprecated error message is done before it even gets to the mu-plugin. In my case the problem is in wp-db.php, where the error is: Deprecated: mysql_connect()
