输出数组中的随机几组数组

//百度知道中的代码,mark一下
$data = array(
            array(
                "price" => "6874","air" => "国泰"
            ),
            array(
                "price" => "4726","air" => "大韩航空"
            ),
            array(
                "price" => "6569","air" => "国泰航空"
            ),
            array(
                "price" => "6569","air" => "卡塔尔航空"
            ),
            array(
                "price" => "3380","air" => "美国航空"
            ),
            array(
                "price" => "4200","air" => "泰国航空"
            )
    );
//随机选择出两个元素
$temp=array_rand($data,2);
//重组数组
foreach($temp as $val){
    $data_last[]=$data[$val];
}
print_R($data_last);
