Sorting an array of objects depending on object attribute

Question

I have an array composed of objects.

[
    {
        "name" => "First",
        "order" => 5
    },
    {
        "name" => "Second",
        "order" => 3
    },
    {
        "name" => "Third",
        "order" => 9
]

How can I order it by ascending "order" value ?

I should get :

[
    {
        "name" => "Second",
        "order" => 3
    },
    {
        "name" => "First",
        "order" => 5
    },
    {
        "name" => "Third",
        "order" => 9
];

You should be able to use the PHP usort() function like this for arrays:

usort($array, function($a, $b){return $a["order"]-$b["order"];});

or for objects:

usort($array, function($a, $b){return $a->order-$b->order;});

Here's the PHP reference: usort()

@Ping - I've added an extra example: same idea, just slightly different syntax for objects. – Jun 28 '13 at 10:12
Thanks, it works ! This helped me a lot to learn about how sorting works. – Lukmo Jun 28 '13 at 10:15
