Re: [PHP] Sort a multi-dimensional array on a certain key followed by another key
Ok so, I have an array [0(index)][1st key][2nd key] Basically I don't care about the index. As a matter of fact I'd prefer it reset to still be in order afterwards. However, I need to sort the 1st key and keep correlation w the second key. Then sort on the second key. I have video volumes and scenes like [0][110][1] [1][110][3] [2][110][2] [3][110][4] Any help would be much appreciated. looks like a job for array_multisort() function http://php.net/array_multisort virgil http://www.jampmark.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Then sort on the second key.
I have video volumes and scenes like
[0][110][1]
[1][110][3]
[2][110][2]
[3][110][4]
Any help would be much appreciated.

$d[3][111][4] = '31104';
recursive_ksort($d);
print_r($d);
?
Seems to work for me. Give it a run and let us know...
