如果名字不用数组的话，php只能获取到最后一个checkbox的值?
<span style="color: #aa7700;">$checkbox</span> = <span style="color: #aa7700;">$_POST</span>[<span style="color: #0000ff;">'checkbox'</span>];?

<strong><span style="color: #006699;">if</span></strong>(!<span style="color: #ff1493;">is_null</span>(<span style="color: #aa7700;">$checkbox</span>[<span style="color: #aa7700;">$i</span>]))?
