Sort an object array by a column

Question

I want to sort my object array by date, which is like that:

$array = array( 
[0] = array ('date' => '2012-05-15', 'name' => 'jon')
[1] = array ('date' => '2012-05-10', 'name' => 'jon')
[2] = array ('date' => '2012-05-09', 'name' => 'jon')
[3] = array ('date' => '2012-05-16', 'name' => 'jon')
);

What method should I use?

Answer 1

uasort() is another option.

$array = array( 
array ('date' => '2012-05-15', 'name' => 'jon'),
array ('date' => '2012-05-10', 'name' => 'jon'),
array ('date' => '2012-05-09', 'name' => 'jon'),
array ('date' => '2012-05-16', 'name' => 'jon')
);

function date_sort($a, $b)
{
    if ( $a['date'] < $b['date'] ) return -1;
    if ( $a['date'] > $b['date'] ) return 1;
    return 0;
}

uasort($array, 'date_sort');
var_dump($array);
