Question

I’m having the following array and I would like to order theme after the prices value. I have been checking in the php manual the array_multisort() function but it’s not really clear how could I achieve results.

my array looks

array=>(0=>array(id=>'1', name=>'example1', price='200'))
array=>(1=>array(id=>'2', name=>'example1', price='120'))
array=>(2=>array(id=>'3', name=>'example1', price='160'))

after the price value the order should be

array=>(1=>array(id=>'2', name=>'example1', price='120'))
array=>(2=>array(id=>'3', name=>'example1', price='160'))
array=>(0=>array(id=>'1', name=>'example1', price='200'))

Use usort():

function cmp ($a, $b) {
    if ($a ['price'] == $b ['price']) {
        return 0;
    }
    return ($a ['price'] < $b ['price']) ? -1 : 1;
}

usort ($array, "cmp");

MonkeyMonkeys’ alternative:

function cmp ($a, $b) {
    return ($a ['price'] - $b ['price']);
}

usort ($array, "cmp");
