Entre autres erreurs, comme indiqué dans mes commentaires à partir de votre code initialement publié.
De plus, vous n'utilisiez pas mysql_query dans la création de votre tableau.
Voici un mysqli_ méthode, où j'ai commenté vos codes d'origine.
Sidenote :Vous utilisez ID pour votre colonne dans $query = "SELECT ID FROM " . $table; et pourtant vous créez votre table et colonne en tant que id en minuscules ; les deux lettres doivent correspondre.
