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;">for</span></strong>(<span style="color: #aa7700;">$i</span>=0;<span style="color: #aa7700;">$i</span><code class="php functions"><span style="color: #ff1493;">count</span>(<span style="color: #aa7700;">$checkbox</span>);<span style="color: #aa7700;">$i</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>]))?
{<span style="color: #aa7700;">$chechvalue</span>=<span style="color: #aa7700;">$checkbox</span>[<span style="color: #aa7700;">$i</span>];<strong><span style="color: #006699;">break</span></strong>;}?
