What is an elegant way to sort objects in PHP? I would love to accomplish something similar to this.
$sortedObjectArary = sort($unsortedObjectArray, $Object->weight);
Basically specify the array I want to sort as well as the field I want to sort on. I looked into multidimensional array sorting and there might be something useful there, but I don't see anything elegant or obvious.
For php >= 5.3
function osort(&$array, $prop)
{
usort($array, function($a, $b) use ($prop) {
return $a->$prop > $b->$prop ? 1 : -1;
});
}
Note that this uses Anonymous functions / closures. Might find reviewing the php docs on that useful.
The usort function (http://uk.php.net/manual/en/function.usort.php) is your friend. Something like...
function objectWeightSort($lhs, $rhs)
{
if ($lhs->weight == $rhs->weight)
return 0;
if ($lhs->weight > $rhs->weight)
return 1;
return -1;
}
usort($unsortedObjectArray, "objectWeightSort");
Note that any array keys will be lost.
