PHP 简易网页访问统计
<p>传统的网页访问统计，已经有很多，如 51la、百度统计、站长统计</p><p>一般都需要引用JS，在你的网页内嵌入JS，这个操作存在风险，并且不可控。</p>
<p>可以考虑使用 【img src、css src、link href】引用统计；</p>
<p><strong>使用方法：</strong></p>
<p>在需要统计页面添加 <img src="/stat.php" /></p>
<p>访问记录按照站点每日存储，记录内容：time、ip、url、user_agent、统计参数（stat.php?xxxx）</p>
<p>使用 stat.php?null=1 禁止输出svg</p>
<p>使用 stat.php?host=xxx 将多个不同站点统计到一起</p>
<p>后期基于记录内容可以分析访问数据；</p>
<p>统计代码的PHP实现：</p>
