array_intersect_uassoc
(PHP 5)
array_intersect_uassoc — Computes the intersection of arrays with additional index check, compares indexes by a callback function
Beskrivelse
$array1
, array $array2
[, array $ ...
], callable $key_compare_func
)
array_intersect_uassoc() returns an array
containing all the values of array1
that are present in all the arguments. Note that the keys are used in
the comparison unlike in array_intersect().
Parametre
-
array1 -
Initial array for comparison of the arrays.
-
array2 -
First array to compare keys against.
-
array -
Variable list of array arguments to compare values against.
-
key_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.
Returnerings Værdier
Returns the values of array1 whose values exist

?>
The above example will output:
Array
(
[b] => brown
