如何在in_array中获取第二个参数的关键字？

Question

I have an array (array01) that contains a bunch of sub arrays consisting of two pieces of data each, like:

Array ( [0] => Array ( [0] => 10CC [1] => Dreadlock Holiday )
        [1] => Array ( [0] => 10CC [1] => I\'m Not In Love )
        [2] => Array ( [0] => 10CC [1] => Dreadlock Holiday ) )
         etc...

I have another array (array02) like:

Array ( [66] => Array ( [0] => 10CC [1] => Dreadlock Holiday )
        [585] => Array ( [0] => 10CC [1] => I\'m Not In Love )
         etc...

I'm successfully using foreach and then in_array to see what array01 elements are in array02. However, what I am struggling to figure out is how to get the id of what element in array2 the hit was on.

So for example, array01's 0 and 2 elements (both 10CC, Dreadlock Holiday), are matched in array02, but how do I get the ID of the element (in this case, 66)?

Thanks for your help.

Have you tried the array_search function?
