Opis
$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().
Parametry
-
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 -
