arrays inside array - sort alphabetically

Question

I have an array that contains many other arrays. The first item is a base64-encoded string and the second item is the real string.

How can i sort the array alphabetically based on the second string ?

with this example i need to sort the sub-arrays alphabetically based on the string starting by "kochise" or "haine brigade"

Have you looked at usort? us3.php.net/manual/en/function.usort.php — user2625787

Here:

function cmp($a, $b)
{
   return strcmp($a[1], $b[1]);
}

usort($your_data, "cmp");

    function aasort(&$yourarrayname, $key) { //this function will do this for you, just input the 

//array name and the  key name for this target array for the association
        $sorter=array(); //here we initialize the arrays to order or sort as you like
        $ret=array();
        reset($yourarrayname); //good code practices
        foreach ($array as $ii => $va) {      //loop through the array and sort each to each in this //new arrays
            $sorter[$ii]=$va[$key]; //storing 
        }
        asort($sorter, SORT_NATURAL | SORT_FLAG_CASE); //assort as alphabetic
        foreach ($sorter as $ii => $va) {
            $ret[$ii]=$array[$ii];
        }
        $array=$ret;
    }
      //call it like this
    aasort($your_array,"key");

@libertaire if you havent found a problem we can go to the chat i know why you have this problem but i need to see how you are populating the array. can you upload the code in which the array gets created?

Easy way to solve this problem is to create the array like this instead: Doing it this way makes you able to use php sort functions.

  Array
(
    ["kochise - 14 - la revanche des vaincus  [www.pirate-punk.net].mp3"] => Array
        (
            [0] => ZGwvcHAvNjI1MC9rb2NoaXNlICsgaGFpbmUgYnJpZ2FkZSAtIHNhdXZhZ2VzIChzcGxpdCkgIFt3d3cucGlyYXRlLXB1bmsubmV0XS56aXAja29jaGlzZSAtIDE0IC0gbGEgcmV2YW5jaGUgZGVzIHZhaW5jdXMgIFt3d3cucGlyYXRlLXB1bmsubmV0XS5tcDMK
            [1] => kochise - 14 - la revanche des vaincus  [www.pirate-punk.net].mp3
