find one of many variables within $array

[Marcus]

Currently I do this, to check if there are values (here: "option x") within an array (here $user...):

if(count(array_diff(array("option 1", "option 2","option 3"), $user['customFields']['cake']))<3)

I use count()<count($check_array) to check once a value was found. Do you have a better and more straight forward solution for this?

in_array($user['customFields']['cake'], $options);

Hi Rigel,

this is right, but in my case $user['customFields']['cake'] is also an array.

The problem is, that I want to find multiple values within an array.

As an example, there is an array full of vegetables. And I have an basked of what I bought at the supermarket. I want to find out if I bought some vegetables. Currently I do it like this: count(array_diff($basket, $vegetables)<count of max difference of either $basket or $vegetables).

In my current easier scenario it is that the first array contains have no, one or multiple values of the second array.

The array_diff and array_intersect functions are for just that... finding stuff that matches (or missing) between multiple arrays. So I think you are doing it the best way possible.

I see.
