How can I sort an array like this so that it would be ASC ordered by the [1] key in subarrays? I need to maintain only the subarray key - value pairs. (Do I make sense?) Array (

    [0] => Array
        (
            [0] => Logo
            [1] => NameC
            [2] => Home
            [3] => url
        )

    [1] => Array
        (
            [0] => Logo
            [1] => NameA
            [2] => Home
            [3] => url
        )

    [2] => Array
        (
            [0] => Logo
            [1] => NameG
            [2] => Home
            [3] => url
        )

}

I think usort would be a bit overkill, he would probably find himself making a function to sort and maintain the association between the subarrays. Go with array_multisort, it would be a one-liner.

What total tosh! array_multisort() won't handle this one -- usort() is correct. The only function needed is a (one-liner!) custom comparison to compare individual [1] elements -- usort() takes care of all the rest: function compare_1($a, $b) { return strcmp($a[1], $b[1]); } usort($array, 'compare_1'); Or even, for single use, collapse it to: usort($array, create_function('$a,$b', 'return strcmp($a[1], $b[1]);'); Cheers!
