[FX.php List] Sorting multidimensional array

[Dale Bengston]

Hi Webko,

I think you have to turn it inside out first, making a new array with  
the record keys being the field value you want to sort.

$sortedDistances = array();
foreach ($theDistances as $value)
	{
	$sortedDistances[$value['Distance']] = $value;
	}

asort($sortedDistances);

That's from pseudocode from memory. Also not a real robust solution  
since it will go wrong if you have two or more identical values for  
$value['Distance']. Still, maybe it will get your brain back on track.

Hope this helps,
Dale
