Get index of element in array and search for it in another array

Question

I want to get the index of an element which I'm looking for using in_array("Tuesday", $day) and get the element from another array on the same position as this one. I have 2 arrays: $day and $action. I need some help with this, I'm stuck.

It's not really clear what you ask, but array_search might be a good start. — Nicolas Brugneaux

Ok, so I'm using the in_array like this: if(in_array("Tuesday, $day)){}. If it is in array, I want to take it's position in the array and print the element on the same position from the other array. — Rawrrr1337

the in_array won't return you any index, it's just a boolean, array_search does the same job and returns the key, ex: $key = array_search("Tuesday, $day); if $key > 0 // do stuff (and you can of course do $action[$key] — Nicolas Brugneaux

$key = array_search("Tuesday", $day); 
if($key !== false)

if ($key > 0) is wrong. Just read the documentation: if ($key !== false) is correct.
