Les indices entiers des tableaux associatifs PHP peuvent être non contigus.
Les indices peuvent comporter des intervalles manquants.
Exemple en PHP.
$arr = array(); initialise un tableau vide.
$arr[0] = 10; associe la valeur 10 à l’indice 0.
$arr[5] = 20; associe la valeur 20 à l’indice 5.
Les valeurs correspondant aux indices 1 à 4 sont indéfinies.
Le tableau contient donc des « trous » dans ses indices.

"Another aspect of PHP associative arrays is that integer indices need not be contiguous. For example,\n\n1 $arr = array();\n\n2 $arr[0] = 10;\n\n3 $arr[5] = 20;\n\nThe values at indices 1 through 4 are undefined and the array contains some “holes” in its indices."
