如何将此数组

 [0] => Array
    (
        [三月外] => Array
            (
                [id] => 1
                [age] => 22
                [birthday] => 10月04日
                [username] => 胡迪
                [distance_birthday_time] => 214
            )

    )

[1] => Array
    (
        [三月外] => Array
            (
                [id] => 6
                [age] => 24
                [birthday] => 12月04日
                [username] => 发给
                [distance_birthday_time] => 275
            )

    )

变成

[0] => Array
    (
        [三月外] => Array
            (
                [0]=>Array
                    (
                        [id] => 1
                        [age] => 22
                        [birthday] => 10月04日
                        [username] => 胡迪
                        [distance_birthday_time] => 214
                    )
                [1]=>Array
                    (
                        [id] => 6
                        [age] => 24
                        [birthday] => 12月04日
                        [username] => 发给
                        [distance_birthday_time] => 275
                    )
            )
    )

笨点的办法吧,还是去foreach 一一比较去吧,可用key来判断当前的key是否存在,存在的话,直接追加到数据后面,否则就当成新元素增加

你这个就只是这种情况 吗?数组里有没有可能是多个元素的呢?

你是想把相同key的合并吧,

foreach($a as $k=>$v){
    $newArray[$k][] = $v;
}
$myAarray[0] = $newArray;
