連続した変数の宣言について効率の良い記述が知りたいです。

入力画面のinputから受け取った値を変数に格納しようとしているのですが、どうも１つずつ記述するのは効率が悪いと思いもっと効率の良い記述がありましたら、是非ご教授願います。m(_ _)m

php
1$number01 = $_POST['number01'];
2$maintenance01 = $_POST['maintenance01'];
3$money01 = $_POST['money01'];
4
5$number02 = $_POST['number02'];
6$maintenance02 = $_POST['maintenance02'];
7$money02 = $_POST['money02'];
8
9$number03 = $_POST['number03'];
10$maintenance03 = $_POST['maintenance03'];
11$money03 = $_POST['money03'];
12
13$number04 = $_POST['number04'];
14$maintenance04 = $_POST['maintenance04'];
15$money04 = $_POST['money04'];
16
17$number05 = $_POST['number05'];
18$maintenance05 = $_POST['maintenance05'];
19$money05 = $_POST['money05'];

命題通りにやるならこうです
(一部微調整)

PHP
1<?PHP
2$name=["number","maintenance","money"];
3$num=range(1,5);
4foreach($name as $val1){
5  foreach($num as $val2){
6    ${$val1."0".$val2}=filter_input(INPUT_POST,$val1."0".$val2);
7  }
8}
9var_dump($number01);
10var_dump($maintenance03);
11var_dump($money05);
12?>
13<form method="post">
14number01:<input type="text" name="number01" value="1"><br>
15maintenance01:<input type="text" name="maintenance01" value="a"><br>
16money01:<input type="text" name="money01" value="100"><br>
17number02:<input type="text" name="number02" value="2"><br>
18maintenance02:<input type="text" name="maintenance02" value="b"><br>
19money02:<input type="text" name="money02" value="200"><br>
20number03:<input type="text" name="number03" value="3"><br>
21maintenance03:<input type="text" name="maintenance03" value="c"><br>
22money03:<input type="text" name="money03" value="300"><br>
23number04:<input type="text" name="number04" value="4"><br>
24maintenance04:<input type="text" name="maintenance04" value="d"><br>
25money04:<input type="text" name="money04" value="400"><br>
26number05:<input type="text" name="number05" value="5"><br>
27maintenance05:<input type="text" name="maintenance05" value="e"><br>
28money05:<input type="text" name="money05" value="500"><br>
29<input type="submit" value="send">
30</form>

配列処理

配列で処理するほうが楽

PHP
1<?PHP
2$name=["number","maintenance","money"];
3foreach($name as $val){
4  $$val=filter_input(INPUT_POST,$val,FILTER_DEFAULT,FILTER_REQUIRE_ARRAY);
5}
6var_dump($number[1]);
7var_dump($maintenance[3]);
8var_dump($money[5]);
9?>
10<form method="post">
11number01:<input type="text" name="number[1]" value="1"><br>
12maintenance01:<input type="text" name="maintenance[1]" value="a"><br>
13money01:<input type="text" name="money[1]" value="100"><br>
14number02:<input type="text" name="number[2]" value="2"><br>
15maintenance02:<input type="text" name="maintenance[2]" value="b"><br>
16money02:<input type="text" name="money[2]" value="200"><br>
17number03:<input type="text" name="number[3]" value="3"><br>
18maintenance03:<input type="text" name="maintenance[3]" value="c"><br>
19money03:<input type="text" name="money[3]" value="300"><br>
20number04:<input type="text" name="number[4]" value="4"><br>
21maintenance04:<input type="text" name="maintenance[4]" value="d"><br>
22money04:<input type="text" name="money[4]" value="400"><br>
23number05:<input type="text" name="number[5]" value="5"><br>
24maintenance05:<input type="text" name="maintenance[5]" value="e"><br>
25money05:<input type="text" name="money[5]" value="500"><br>
26<input type="submit" value="send">
