array_uintersect_uassoc

(PHP 5)

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

Descrizione

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

Elenco dei parametri

array1

The first array.

array2

The second array.

value_compare_func

La funzione di confronto deve restituire un intero minore, uguale o maggiore di zero se il primo argomento è considerato essere minore, uguale o maggiore del secondo.

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

Key comparison callback function.

Valori restituiti

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

<?php
$array1 
= array("a" => "green""b" => "brown""c" => "blue""red");
$array2 = array("a" => "GREEN""B" => "brown""yellow""red");

print_r(array_uintersect_uassoc($array1$array2"strcasecmp""strcasecmp"));
?>

Il precedente esempio visualizzerà:

Array
(
    [a] => green
    [b] => brown
)

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.
