(PHP 5)

array_uintersect_uassocComputes the intersection of arrays with additional index check, compares data and indexes by a callback functions

Opis

array array_uintersect_uassoc ( array $array1 , array $array2 [, array $ ... ], callable $data_compare_func , callable $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.

Parametry

array1

The first array.

array2

The second array.

data_compare_func

The comparison function 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.

int callback ( mixed $a, mixed $b )
key_compare_func

Key comparison callback function.

Zwracane wartości

Returns an array containing all the values of array1 that are present in all the arguments.

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.
