array_intersect_uassoc Computes the intersection of arrays with additional index check, compares indexes by a callback function &reftitle.description; arrayarray_intersect_uassoc arrayarray1 arrayarray2 array... callablekey_compare_func array_intersect_uassoc returns an array containing all the values of array1 that are present in all the arguments.
