#1 connexion mysql

[Jouve]

Hi all
I can connect mysql with php

$pdo_options[PDO::ATTR_ERRMODE] = PDO::ERRMODE_EXCEPTION;
$bdd = new PDO('mysql:host=mysql-m;dbname=m751682_test', 'm751682admin', '****', $pdo_options);

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [2005] Unknown MySQL server host 'mysql-m' (1)'

Can you help me

Thanks :)
