输出：
原来数据
array( [0] => array ( [id] => 0 ) [1] => array ( [id] => 1 ) [2] => array ( [id] => 2 ) [3] => array ( [id] => 3 ))加入dept后
array( [0] => array ( [id] => 0 [dept] => 783 ) [1] => array ( [id] => 1 [dept] => 683 ) [2] => array ( [id] => 2 [dept] => 442 ) [3] => array ( [id] => 3 [dept] => 121 ))重新遍历，最后一个元素的竟然得到的竟然是前一个元素？
array( [id] => 0 [dept] => 783)
array( [id] => 1 [dept] => 683)
array( [id] => 2 [dept] => 442)
array( [id] => 2 [dept] => 442)
以上就介绍了php 奇怪现象，求大神解答，包括了方面的内容，希望对php教程有兴趣的朋友有所帮助。
