Sort Array Subkey Based on Another Array's Order

[rygotype]

I know there have been many posts regarding array sorting, but I have looked high and low and cannot find a solution to my problem.

I have found a very good article here: http://firsttube.com/read/sorting-a-multi-dimensional-array-with-php/

The above link is great, however, I wish to take it further and sort the array subkey based off the order of another array.

So, let’s say we have five songs in the Playlist Array:

Array ( [0] => 3oh!3 - Don't Trust me [1] => Taylor Swift - You Belong with me [2] => Sean Kingston - Fire Burning [3] => Green Day - Know Your Enemy [4] => Kelly Clarkson - Gone )

And let’s say we have the following information that we would like sorted to match the order of our Playlist Array:

[code]Array
(
[0] => Array
(
[trackName] => Taylor Swift - You Belong With Me
[trackLength] => 0
[trackViews] => 0
[trackRating] => 0
)

[1] => Array
    (
        [trackName] => Sean Kingston - Fire Burning
        [trackLength] => 0
        [trackViews] => 0
        [trackRating] => 0
    )

[2] => Array
    (
        [trackName] => 3OH!3- Dont Trust Me 
        [trackLength] => 205
        [trackViews] => 4570399
        [trackRating] => 4.866372
    )

[3] => Array
    (
        [trackName] => Green Day Know Your Enemy 
        [trackLength] => 191
        [trackViews] => 4715494
        [trackRating] => 4.9103785
    )

[4] => Array
    (
        [trackName] => Kelly Clarkson: Gone 
        [trackLength] => 225
        [trackViews] => 679019
        [trackRating] => 4.8995433
    )

)
[/code]
So, again… My question is: How can I get the array of songs to be sorted by the trackName to match the same order of the Playlist Array?

Any help or guidance would be appreciated!

Thanks,

[SOLUTION]
Check’s the playlist order, then sorts the trackName of each song in the playlist after all the songs have been gathered and inserted to the array. Then checks the song titles of the playlist and each looked up song for a 75% similarity match since the song titles looked up can vary slightly depending on the source it was found on.

[php]$sorted_list = array();

foreach($songs as $song_key=>$song){
foreach($song_info as $info){
similar_text($info[‘trackName’], $song, $p);
if($p >= 75){
$sorted_list[$song_key] = $info;
}
}
}[/php]
