昨天在做数据库批量导入的时候遇到的老问题（foreach+&问题）
问题可以简要的概括为：

$arr = array(1,2,3,4,5);<br />
foreach($arr as $key => &$row) {}<br />
foreach($arr as $key => $row) {}<br />
var_dump($arr);
Copy after login

array (size=5)<br />
  0 => int 1<br />
  1 => int 2<br />
  2 => int 3<br />
  3 => int 4<br />
  4 => &int 4
Copy after login

foreach 指针问题，指针大神，求现身！
