array_uintersect_uassoc (PHP 5) array_uintersect_uassoc -- Computes the intersection of arrays with additional index check, compares data and indexes by a callback functions Descriptionarray array_uintersect_uassoc ( array array1, array array2 [, array ..., callback data_compare_func, callback key_compare_func])
array_uintersect_uassoc() returns an array
containing all the values of array1
that are present in all the arguments. Note that the keys are used in

Both the data and the indexes are compared by using a callback functions.
例子 1. array_uintersect_uassoc() example |

Please note, the correct function synopsis is:
array
array_uintersect_uassoc ( array array1, array array2 [, array ...],
callback data_compare_func, callback key_compare_func)
You may
specifiy as many arrays as you like, but the last two parameters must be
valid call back functions.
