array_uintersect_uassoc

Description

array_uintersect_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_uintersect(). Both the data and the indexes are compared by using a callback functions.

Beispiel 1. array_uintersect_uassoc() example <?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")); ?> Das oben gezeigte Beispiel erzeugt folgende Ausgabe: Array ( [a] => green [b] => brown )

For comparison is used the user supplied callback function. It 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.
