array_uintersect_assoc
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.
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
설명
array array_uintersect_uassoc
( array $array1
, array $array2
[, array $ ...
], callback $data_compare_func
, callback $key_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.
