j'ai bien crée mes tables mysql, tout marche sauf que j'ai ce message:

Notice: Undefined variable: me in D:\EasyPHP5.3.0\www\poll.php on line 24

Warning: max() [function.max]: When only one parameter is given, it must be an array in D:\EasyPHP5.3.0\www\poll.php on line 24
merci de bien vouloir m'aider

Chez mysql on utilise ` ou rien pour les noms d'objets mais pas '

Pour avoir le plus grand compte, fait le directement dans ta requête :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

$query = mysql_query("SELECT COUNT(*) as hits FROM responses GROUP BY qid ORDER BY hits DESC LIMIT 1");
