RE: [PHP] Sorting an array of arrays....
Good day, uasort() should do what you need. http://www.php.net/manual/en/function.uasort.php There's an example for the usort function that does something similar to what you want, in fact.

RE: [PHP] Sorting an array of arrays....
Does anyone have an example of code that does this, I have been trying to decipher the instructions on the use of uasort but it does not make a hole lot of sense. They are using static keys and sorting by one of the array elements of each of there static keys. It does not seem like one should have to do it this way. I need it to go through each key and sort the keys based on a value in the array held in that key.

Re: [PHP] Sorting an array of arrays....
try to add to your script:
function cmp ($a, $b) {
return strcmp($a[3],$b[3]);
}
usort($data, cmp);
