array_intersect_uassoc
(PHP 5, PHP 7)
array_intersect_uassoc — Computes the intersection of arrays with additional index check, compares indexes by a callback function
Descrierea
array_intersect_uassoc() returns an array
containing all the values of array
that are present in all the arguments. Note that the keys are used in
the comparison unlike in array_intersect().
Parametri
-
array -
Initial array for comparison of the arrays.
-
arrays -
Arrays to compare keys against.
-
key_compare_func -
Funcția de comparare trebuie să întoarcă un întreg mai mic, egal cu sau mai mare decât zero dacă primul argument este considerat respectiv mai mic, egal cu sau mai mare decât al doilea argument. Notă: înainte de PHP 7.0.0 acest întreg trebuia să fie cuprins în domeniul de la -2147483648 până la 2147483647.
Valorile întoarse
Returns the values of array whose values exist
in all of the arguments.
Exemple
Example #1 array_intersect_uassoc() example
<?php
$array1 = array("a" => "green", "b" => "brown", "c" => "blue", "red");
$array2 = array("a" => "GREEN", "B" => "brown", "yellow", "red");
print_r(array_intersect_uassoc($array1, $array2, "strcasecmp"));
?>
Exemplul de mai sus va afișa:
Array

[b] => brown
