Sort Multi Array in PHP

Question

Does anybody have an idea how can I sort this array by key (date) in PHP?

Array
(   
    [2011-02-16] => Array
        (
            [date] => 2011-02-16
          


        

Answer 1

Sure thing. I answered this exact post yesterday, too.

Sorting 2 arrays to get the highest in one and lowest in another

In your case, it will be something like...

$myArray= subval_sort($myArray,'date'); 

function subval_sort($a,$subkey) {
    foreach($a as $k=>$v) {
        $b[$k] = strtolower($v[$subkey]);
    }
    asort($b);
    foreach($b as $key=>$val){
        $c[] = $a[$key];
    }
    return $c;
}

The answer by shamittomar is better though :)
