Array Question

[ljschrenk]

Hey Everyone,

I think I've just been staring at this for too long, I have a pretty simple question. I have an array of over 300 values that go in an order like this:

name, number, street, state, name, number, street, state etc...

I need to extract 'number' and create a new array of all the 'number'(s). Does this make sense?

I would appreciate any direction. Thanks!!

I find this function helpful in associative arrays:

function subarray($source_array, $field) {      

//Creates an array from a field in a multi-dimensional array.

    $target_array=array();
    foreach ($source_array as $s) {
            $target_array[]=$s[$field];
            }
    return $target_array;
}

If it's just a numeric array, you'd have to modify it to check a modulus and append to the $target_array based on that ...
