通用PHP动态生成静态HTML网页的代码_PHP
我们知道,PHP读取MYSQL动态显示,在访问量大的情况下,会有很多性能问题,如果租用别人的虚拟主机,则会因为CPU消耗过多而被限制CPU,导致网页无法访问。我这里给出一个PHP动态生成HTML的方法,可以极大降低服务器CPU负荷。
首先设置.htaccess文件,将动态调用的参数转换为静态的HTML的URL地址,例如将在post目录下的文件,转发到根目录的wp-post.php文件中,加入的语句类似:
RewriteRule ^post/([a-z0-9\-]+\.html)$ wp-post.php?$1$2
然后修改wp-post.php文件,在文件的开头加入以下PHP代码:
复制代码 代码如下:
ob_start();
$qstring = isset($_SERVER[%26quot;QUERY_STRING%26quot;]) ? $_SERVER[%26quot;QUERY_STRING%26quot;] : %26quot;%26quot;;
define(%26quot;HTML_FILE%26quot;, $_SERVER['DOCUMENT_ROOT'].%26quot;/post/%26quot;.$qstring);
if (file_exists(HTML_FILE))
{
$lcft = filemtime(HTML_FILE);
if (($lcft + 3600) %26gt; time()) //判断上次生成HTML文件是否超过1小时,若没有才直接输出文件内容
{
echo(file_get_contents(HTML_FILE));
exit(0);
}
}
之后是现有的PHP的代码,然后在当前代码的最后面加上如下的PHP代码:
复制代码 代码如下:
define(%26quot;HTMLMETA%26quot;,%26quot;%26lt;!-- this is a real static html file created at %26quot;.date(%26quot;Y-m-d H:i:s%26quot;).%26quot; --%26gt;%26quot;);
$buffer = ob_get_flush();
$fp = fopen(HTML_FILE, %26quot;w%26quot;);
if ($fp)
{
fwrite($fp, $buffer.HTMLMETA);
fclose($fp);
}
好了,然后查看你的静态HTML页面,如果页面尾部出现了注释行,说明已经成功的创建了静态HTML文件。
这个方法的一个应用就是我先前写的那个%26ldquo;WordPress年度博客统计插件%26rdquo;,这个统计插件由于查询十多次数据库,很多人访问的时候会有很大性能问题,使用我介绍的这种动态生成HTML技术后,一天就查询一次,生成一次统计排行,完美解决了查询数据库的性能问题。
