foreach 兩層改變原值，請大神賜教

如下要怎麼做

$data = [1,2,3,[a,b,c]];foreach($data as &$e){    //$data數組裡的數量不確定，一維數組各加1，二維數組各拼接m    }var_dump($data);//[2,3,4,[am,bm,cm]]unset($e);

$data = [1,2,3,['a','b','c']];foreach($data as &$e){    //$data數組裡的數量不確定，一維數組各加1，二維數組各拼接m    if(is_array($e)){        foreach ($e as $k => &$v) {            $v = $v.'m';        }    }else{        $e = $e + 1;    }    }print_r($data);//[2,3,4,[am,bm,cm]]

 &$value) {        if(is_array($value)){            foreach($value as &$v){                $v.= 'm';            }        } else {            ++$value;        }     }}$array = array(1, 2, 3, array('a', 'b', 'c'));test($array);print_r($array);

運行結果如下：
Array
(

[0] => 2[1] => 3[2] => 4[3] => Array    (        [0] => am        [1] => bm        [2] => cm    )

)
