sorting an array

[fnbcprog]

How would I sort this array by the first element?

var $SECTORS = array(
		array('home','/',1,''),
		array('calendar','/',1,''),
		array('courses','/',1,''),
		array('gradebook','/',1,''),
		array('assessments','/',1,''),
		array('preferences','/',1,''),
		array('documents','/',1,''),
		array('communication','/',1,''),
		array('help','/',1,''),
		array('support','/',1,''),
		array('logout','/',1,'')
	); // End Navigation buttons array

so that the result after sorting would be

var $SECTORS = array(
	array('assessments','/',1,''),
	array('calendar','/',1,''),
	array('communication','/',1,''),
	array('courses','/',1,''),
	array('documents','/',1,''),
	array('gradebook','/',1,''),
	array('help','/',1,''),
	array('home','/',1,''),
	array('logout','/',1,'')
	array('preferences','/',1,''),
	array('support','/',1,''),
); // End Navigation buttons array

function my_sort($a, $b) {
	if ($a[0] < $b[0]) return -1;
	if ($a[0] > $b[0]) return 1;
	return 0;
}

usort($SECTORS, 'my_sort');

You can run [man]array_multisort[/man] on it and it'll work with just the array as a parameter, but if you want more voodoo than that you can add more params and watch it go deeper
