Sort object as value with int and text value

I have a object and have a problem, this object here $product have this keys ( product_title, product_price, product_stock ) and more, I need to sort after product_title and if my object have this products in I can't sort it right.

test product 1
test product 11
test product 111
test product 2
test product 20
test product 3
test product 33
test product 333

The right way to sort it its like this:

test product 1
test product 2
test product 3
test product 11
test product 33
test product 20
test product 111
test product 333

I have tried sort and rsort without开发者_运维知识库 luck.

If it can help, my object looks like this:

array(8) {
  [0]=>

and I need to sort after

array(8) {
  [0]=>
  object(stdClass)#12 (49) {
    ["product_title"]=>
    string(10) "Fadestativ"
}

Well, assuming that they are objects (which from your description and comments they appear to be), you can use a usort.

PHP 5.3+:

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

PHP <= 5.2:

usort(
    $array;
    create_function('$a, $b', 'return strnatcmp($a->title, $b->title);`)
);

Change ->title to whatever property you want to sort by. And if you want case insensitivity, use strnatcasecmp instead of strnatcmp()...

Try sort() again but you will have to use a second parameter:

sort($array, SORT_STRING);
