array_uintersect_assoc Computes the intersection of arrays with additional index check, compares data by a callback function &reftitle.description; arrayarray_uintersect_assoc arrayarray1 arrayarray2 array ... callbackdata_compare_func Computes the intersection of arrays with additional index check, compares data by a callback function. 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 For comparison is used the user supplied callback function. It must return an integer less than, equal to, or greater than zero if the first argument is considered to be respectively less than, equal to, or greater than the second. &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
