array_uintersect_uassoc Computes the intersection of arrays with additional index check, compares data and indexes by a callback functions &reftitle.description; arrayarray_uintersect_uassoc arrayarray1 arrayarray2 array ... callbackdata_compare_func callbackkey_compare_func Computes the intersection of arrays with additional index check, compares data and indexes by a callback functions Note that the keys are used in the comparison unlike in array_uintersect. Both the data and the indexes are compared by using separate callback functions. &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. key_compare_func Key comparison callback function. &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"); $array2 = array("a" => "GREEN", "B" => "brown", "yellow", "red"); print_r(array_uintersect_uassoc($array1, $array2, "strcasecmp", "strcasecmp")); ?> ]]> &example.outputs; green [b] => brown ) ]]> &reftitle.seealso; array_uintersect array_intersect_assoc array_intersect_uassoc array_uintersect_assoc
