php二维数组排序

定义二维数组

$arr = array(
    0 => array(
        "id" => 1,
        "ord" => 1,
        "name" => "网站模板"
    ),
    1 => array(
        "id" => 1,
        "ord" => 8,
        "name" => "jQuery特效"
    ),
    2 => array(
        "id" => 1,
        "ord" => 5,
        "name" => "网站源码"
    )
);

首先将ord提取出来存储到一维数组里，然后按照ord升序排列

foreach ($arr as $v) {
    $ords[] = $v['ord'];
}
array_multisort($arr, SORT_ASC, $ords);
