Sorting an array with stdClass Objects - php

Question

I am attempting sort this array by each stdClass Object's [title] in an Ubercart order.tpl.php file. I have tried doing just a normal sort but since they all are stdClass Objects it doesn't do anything.
<pre>Array
(
[0] => stdClass Object
(
[order_product_id] => 1157
[order_id] => 142
[nid] => 38
[title] => Eatonville Forest Camping Permit
[manufacturer] =>
[model] => eatonville-camp-permit
[qty] => 1
[cost] => 9.00000
[price] => 10.00000
[weight] => 0
[data] => Array
(
[attributes] => Array
(
)
[shippable] => 0
[restrict_qty] => 1
[module] => uc_product
)
[order_uid] => 13
)
[1] => stdClass Object
(
[order_product_id] => 1158
[order_id] => 142
[nid] => 35
[title] => Eatonville Forest Motorized Recreation Access Permit and Release of Liability
[manufacturer] =>
[model] => eatonville-motor-rec-access
[qty] => 1
[cost] => 175.00000
[price] => 175.00000
[weight] => 0
[data] => Array

[shippable] => 1
[restrict_qty] => 1
[module] => uc_product

[order_uid] => 13
)
[2] => stdClass Object

[order_product_id] => 1159
[order_id] => 142

[3] => stdClass Object

[4] => stdClass Object

[order_product_id] => 1161

[order_uid] => 13
)
[5] => stdClass Object
(
[order_product_id] => 1162
[order_id] => 142

[title] => White River Forest Family Non-motorized Recreation Access Permit for Families and Release of Liability

[6] => stdClass Object
(
[order_product_id] => 1163
[order_id] => 142
[nid] => 33
[title] => White River Forest Non-motorized Recreation Access Permit for Individuals and Release of Liability
[manufacturer] =>

[qty] => 1
[cost] => 75.00000
[price] => 75.00000
[weight] => 0
[data] => Array
(
[attributes] => Array
(
)
[shippable] => 1
[restrict_qty] => 1
[module] => uc_product
)
[order_uid] => 13
)
[7] => stdClass Object
(
[order_product_id] => 1164
[order_id] => 142
[nid] => 34
[title] => Snoqualmie Forest Non-motorized Recreation Access Permit for Individuals and Release of Liability
[manufacturer] =>
[model] => snoqualmie-non-motor-rec-access
[qty] => 1
[cost] => 75.00000
[price] => 75.00000
[weight] => 0
[data] => Array

[attributes] => Array
(
)
[shippable] => 1
[restrict_qty] => 1
[module] => uc_product
)
[order_uid] => 13
)
)</pre>
This is the code controlling it in the order.tpl.php
<pre>php if (is_array($order->products)) {
$context = array(
'revision' => 'formatted',
'type' => 'order_product',
'subject' => array(
'order' => $order,
),
);
}
</pre>

I think usort() should work:
function sortByTitle($a, $b){
return strcmp($a->title, $b->title);
}
usort($theArray, 'sortByTitle');
You may want to throw in some checking to make sure the title member actually exists.
