array_intersect_uassoc 带索引检查计算数组的交集，用回调函数比较索引 &reftitle.description; arrayarray_intersect_uassoc arrayarray1 arrayarray2 array ... callablekey_compare_func array_intersect_uassoc 返回一个数组，该数组包含了所有在 array1 中也同时出现在所有其它参数数组中的值。注意和 array_intersect 不同的是键名也用于比较。 &reftitle.parameters; array1 Initial array for comparison of the arrays. array2 First array to compare keys against. array Variable list of array arguments to compare values against. key_compare_func &return.callbacksort; &callback.cmp; &reftitle.returnvalues; Returns the values of array1 whose values exist in all of the arguments. &reftitle.examples; "green", "b" => "brown", "c" => "blue", "red"); $array2 = array("a" => "GREEN", "B" => "brown", "yellow", "red"); print_r(array_intersect_uassoc($array1, $array2, "strcasecmp")); ?> ]]> &example.outputs; brown ) ]]> &reftitle.seealso; array_intersect array_intersect_assoc array_uintersect_assoc array_uintersect_uassoc array_intersect_key array_intersect_ukey
