Caching static page classes

/** * Cache Static Page class */class htmlcache{     /**     * Open Cache     * $filename cache full path     * $time cache time Unit is seconds, default 7,200 seconds    */ Public Function Cache_start ($filename, $time =7200)    {        $cachefile = $filename;        $cachetime = $time;        Ob_start ();        if (file_exists ($cachefile) && (Time ()-$cachetime < Filemtime ($cachefile))//Determine if the file exists or is within the cache time        {            include ($cachefile);            Ob_end_flush ();            Exit;        }      }    /**     * End Cache     * $filename cache full Path     *    /Public Function cache_end ($filename) {        $cachefile = $ filename;        $fp = fopen ($cachefile, ' W ');        Fwrite ($FP, ob_get_contents ());        Fclose ($FP);        Ob_end_flush ();      }} Usage: $HtmlCache = new Htmlcache (); $filename = "./cache.html"; $HtmlCache->cache_start ($filename);    The following is the output content, placed between the Cache_start and Cache_end two methods    echo "cache"; $HtmlCache->cache_end ($filename);

The above describes the cache static page class, including the content of the cache, I hope the PHP tutorial interested in a friend helpful.
