Answer 1

尝试这个

 $yourarray = array(array(...), array(....),.....);

 function myFieldSort($a, $b)
 {
   return $b['created'] - $a['created'];
 }

 usort($yourarray, "myFieldSort");

Answer 2

function array_multi_subsort($array, $subkey)
{
    $b = array(); $c = array();

    foreach ($array as $k => $v)
    {
        $b[$k] = strtolower($v[$subkey]);
    }

    asort($b);
    foreach ($b as $key => $val)
    {
        $c[] = $array[$key];
    }

    return $c;
}

// sorting through "created" element in the arrays
$data = array_multi_subsort($array, 'created');
print_r($data);

还可以参考 PHP.net 手册：
http://php.net/manual/en/function.array-multisort.php

Answer 3

请试试这个：

function array_multi_subsort($array, $subkey)
{
    $b = array(); $c = array();

    foreach ($array as $k => $v)
    {
        $b[$k] = strtolower($v->$subkey);
    }

    asort($b);
    foreach ($b as $key => $val)
    {
        $c[] = $array[$key];
    }

    return $c;
}

// sorting through "created" element in the arrays
$data = array_multi_subsort($array, 'created');
print_r($data);
