mysql5.5 hint Deprecated:mysql_query (): The MySQL extension is deprecated

From the wrong hint is not recommended to use the Mysql_connect function, and then I see from the official to say that later do not use the Mysql_connect function, recommended using MYSQLI or PDO to replace, know the reason to solve the convenience.

Workaround 1: Set the alarm level in the PHP program code

<?php
error_reporting = E_all & ~e_deprecated

Method 2: Disable PHP error

Display_errors = on changed to Display_errors = Off

Method 3: Use Mysqli or PDO

We recommend that you cancel MySQL as soon as possible, all toward mysqli or PDO and so on. MySQL is really unsafe and too old.

Small Tips

The second method is a temporary solution, but it is also the most commonly used solution, now have n multiple programs are connected to the database with Mysql_connect Oh.
