how to split arrays inside a big array to fit intersect function?

Question

I have the following array that contains other arrays:

$bigArray = [$array_one, $array_two, $array_three,.... ];

I want to array_intersect the inner arrays like so:

$intersect = array_intersect($array_one, $array_two, $array_three,....);

How do I handle it?

Like this:

$intersect = array_intersect(...$bigArray);

The ... operator, introduced in PHP 5.6, allows you to use an array to pass multiple function arguments.

It's also possible to do this with call_user_func_array, but argument unpacking offers some advantages over that approach.

call_user_func_array('array_intersect', $bigArray); this also works for me

@SolimanMahmoudSoliman yes, before PHP 5.6, that was the standard way to do this. You can check out the RFC for more info: wiki.php.net/rfc/argument_unpacking, specifically the "Advantages over call_user_func_array" section.
