Note that the keys are used in the comparison unlike in array_uintersect. The data is compared by using a callback function. &reftitle.parameters; array1 The first array. array2 The second array. data_compare_func &return.callbacksort; &callback.cmp; &reftitle.returnvalues; Returns an array containing all the values of array1 that are present in all the arguments. &reftitle.examples; "green", "b" => "brown", "c" => "blue", "red"); $array2 = array("a" => "GREEN", "B" => "brown", "yellow", "red"); print_r(array_uintersect_assoc($array1, $array2, "strcasecmp")); ?> ]]> &example.outputs; green ) ]]> &reftitle.seealso; array_uintersect array_intersect_assoc array_intersect_uassoc array_uintersect_uassoc
