hey kiddies

what I'm looking to do is this:

say i have a multidimensional array like so:

code:

---

[0] => {
  ['name'] => "Baby, Please Don't Go"
  ['artist'] => {
                [0]=> "AC/DC"
                }
}
[1] => {
  ['name'] => "Tequila"
  ['artist'] => {
                [0] => "A.L.T. and The Lost Civilization"
                }
}
[2] => {
  ['name'] => "Show You Love Me"
  ['artist'] => {
                [0] => "A.K. Soul"
                [1] => "Jocelyn Brown"
                }
}
[3] => {
  ['name'] => "Dog Eat Dog"
  ['artist'] => {
                [0] => "AC/DC"
                }
}

---

How can I get it to sort by a specific key, for example the first artist key, alphabetically so it ends up like this:

code:

---

[0] => {
  ['name'] => "Baby, Please Don't Go"
  ['artist'] => {
                [0]=> "AC/DC"
                }
}
[1] => {
  ['name'] => "Dog Eat Dog"
  ['artist'] => {
                [0] => "AC/DC"
                }
}
[2] => {
  ['name'] => "Show You Love Me"
  ['artist'] => {
                [0] => "A.K. Soul"
                [1] => "Jocelyn Brown"
                }
}
[3] => {
  ['name'] => "Tequila"
  ['artist'] => {
                [0] => "A.L.T. and The Lost Civilization"
                }
}

I hope that is clear enough lol i hope it's possible

btw its in PHP

Have a look at some of these examples, you should be able to work out how to use it how you want.

http://au2.php.net/manual/en/function.array-multisort.php

I had a look at that and from what i understand of what it does, it actually doesn't so what i want it to, if i undersatnd it correctly that functino will only sort within on branch of the array (ie. if i have multiple [artist] thingies on one particular branch then it will sort within those artists) but it will not rearrange the entire array, which is what i need it to do lol

array_multisort() should work fine for that. Here's an example of how you could use it...

code:

---

$songs = array(); // Your data would be in here
$artists = array(); // Temporary array

foreach($songs as $key => $song) {
    // Copy the first artist name
    $artists[$key] = $song['artist'][0];
}

array_multisort($artists, $songs);

You should also keep in mind that if the data is coming from a database, you can easily tell the database to return it presorted...
