Deprecated: mysql_connect()

Question

I am getting this warning, but the program still runs correctly.

The MySQL code is showing me a message in PHP:

Deprecated: mysql_connect(): T

Answer 1

PDO class replaces these methods. Example for Mysql or MariaDB :

$BDD_SQL = new PDO('mysql:host='.BDD_SQL_SERVER.';dbname='.BDD_SQL_BASE.';charset=utf8', 
        BDD_SQL_LOGIN, BDD_SQL_PWD, 
        array(
          PDO::ATTR_EMULATE_PREPARES => false,
          PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION, //launch exception if error
          PDO::ATTR_DEFAULT_FETCH_MODE=> PDO::FETCH_ASSOC
                ));
