array intersect for object array php

Question

I want to know how to array_intersect for object array.

Answer 1

You can use array_uintersect in conjunction with spl_object_hash, see an example:

    array_uintersect($a, $b, function($a, $b) {
        return strcmp(spl_object_hash($a), spl_object_hash($b));
    });

where '$a' and '$b' are arrays of some objects that you want to intersect.
