Answer taken from this post: Sort array of objects by object fields

Use usort , here's an example adapted from the manual:

function cmp($a, $b)
{
    return strcmp($a->name, $b->name);
}

usort($your_data, "cmp");

If you're sorting the array from inside the class and your sorting function cmp is also defined inside the class, then use this:

usort($your_data, array($this, "cmp"))
