Question : Finding the array id based on value of key.

Below is a sample array that I might pull from one of my radios, the goal is to find the array id based on a given mac-address.

For example using the following array, If the mac address being searched for is "00:00:00:00:00:EF" then I need to set a variable to "0" if it is "00:00:00:00:00:ED" then I need to set it to "1".

Hope that makes sense.

Answer : Finding the array id based on value of key.

You might use a foreach iterator to walk the array of arrays. You would look at something like this (untested code)

                       
             <?php
foreach ($main_array as $k => $sub_array)
{
    if ($sub_array[mac-address] == '00:00:00:00:00:ED') echo $k;

}

You might use a foreach iterator to walk the array of arrays. You would look at something like this (untested code) 1: 2: 3: 4: 5: 6: <?php foreach ($main_array as $k => $sub_array) { if ($sub_array[mac-address] == '00:00:00:00:00:ED') echo $k; }
