Cahe php site web jour 1

Bonjour,
Je suis le tuto Cake php pour créer un site web et j'ai une erreur avec mysql :

Strict (2048): Declaration of Mysql::describe() should be compatible with DataSource::describe($model) [CORE\Cake\Model\Datasource\Database\Mysql.php, line 29]

Mon code mysql est :

<?php
