Combining two arrays by ID in PHP
===

I need to compare two 2D arrays in PHP. The arrays look like this:

    Array one
    ID Name
    11 Aa 
    12 Bb
    13 Cc
    14 Dd
    15 Ee

    Array two
    ID Content
    11 Cat
    13 Dog
    14 Donkey

Now I'd need to combine these two into an array like this:

    ID Name Conent
    11 Aa Cat
    12 Bb
    13 Cc Dog
    14 Dd Donkey
    15 Ee

How can I accomplish this? I have had no luck with array_merge() or $array3 = $array1 + $array2;
