array_uintersect_assoc

(PHP 5, PHP 7, PHP 8)

array_uintersect_assocComputes the intersection of arrays with additional index check, compares data by a callback function

Descrizione

array_uintersect_assoc(array $array, array ...$arrays, callable $value_compare_func): array

Computes the intersection of arrays with additional index check, compares data by a callback function.

Note that the keys are used in the comparison unlike in array_uintersect(). The data is compared by using a callback function.

Elenco dei parametri

array

The first array.

arrays

Arrays to compare against.

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.

callback(mixed $a, mixed $b): int
Attenzione

Returning non-integer values from the comparison function, such as float, will result in an internal cast to int of the callback's return value. So values such as 0.99 and 0.1 will both be cast to an integer value of 0, which will compare such values as equal.

Valori restituiti

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

Example #1 array_uintersect_assoc() example

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

print_r(array_uintersect_assoc($array1, $array2, "strcasecmp"));
?>

Il precedente esempio visualizzerà:

Array
(
    [a] => green
)
