PHP 配列を回すならforかforeach

1. $list = array();
2. $list[] = array(‘id’ => 1, ‘name’ => ‘hoge’);
3. $list[] = array(‘id’ => 2, ‘name’ => ‘foo’);
4. $list[] = array(‘id’ => 3, ‘name’ => ‘bar’);
5.  
6. echo “for：\n”;
7. for ($i = 0 ; $i <count($list); $i++) {
8. 　echo $i . “：” . $list[$i][‘id’] . “：” . $list[$i][‘name’] . “\n”;
9. }
10.  
11. echo “\n”;
12.  
13. echo “foreach：\n”;
14. foreach ($list as $i => $rec) {
15. 　echo $i . “：” . $rec[‘id’] . “：” . $rec[‘name’] . “\n”;
16. }

foreach：
0：1：hoge
1：2：foo
2：3：bar
