How to prevent PHP deprecated warning messages?

Answer

On the error_reporting reporting line of your php.ini file:

error_reporting = E_ALL

You will want to add ~E_DEPRECATED after the E_ALL, so that it looks similar to the following line, and save the file:

error_reporting = E_ALL & ~E_DEPRECATED
