wordpress 不使用插件 实现 页面静态化

本文介绍如果将wordpress 页面静态化,(不依赖插件
 
功能:
首次访问页面会生成静态页面,可以设定生成静态文件时间,超过指定时间重新生成。
 
修改项目入口文件 index.php(提前备份):
 
function is_mobile(){

$regex_match="/(nokia|iphone|android|motorola|^mot\-|softbank|foma|docomo|kddi|up\.browser|up\.link|";
$regex_match.="htc|dopod|blazer|netfront|helio|hosin|huawei|novarra|CoolPad|webos|techfaith|palmsource|";
$regex_match.="blackberry|alcatel|amoi|ktouch|nexian|samsung|^sam\-|s[cg]h|^lge|ericsson|philips|sagem|wellcom|bunjalloo|maui|";
$regex_match.="symbian|smartphone|midp|wap|phone|windows ce|iemobile|^spice|^bird|^zte\-|longcos|pantech|gionee|^sie\-|portalmmm|";
$regex_match.="jig\s browser|hiptop|^ucweb|^benq|haier|^lct|opera\s*mobi|opera\*mini|320x320|240x320|176x220";
$regex_match.=")/i";
return isset($_SERVER['HTTP_X_WAP_PROFILE']) or isset($_SERVER['HTTP_PROFILE']) or preg_match($regex_match, strtolower($_SERVER['HTTP_USER_AGENT']));

}

$requestUri = '';
if (isset($_SERVER['REQUEST_URI'])) { #$_SERVER["REQUEST_URI"] 只有 apache 才支持,
$requestUri = $_SERVER['REQUEST_URI'];
} else {
if (isset($_SERVER['argv'])) {
$requestUri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['argv'][0];
} else if(isset($_SERVER['QUERY_STRING'])) {
$requestUri = $_SERVER['PHP_SELF'] .'?'. $_SERVER['QUERY_STRING'];
}
}
$scheme = empty($_SERVER["HTTPS"]) ? '' : ($_SERVER["HTTPS"] == "on") ? "s" : "";
$protocol = strstr(strtolower($_SERVER["SERVER_PROTOCOL"]), "/",true) . $scheme;
$port = ($_SERVER["SERVER_PORT"] == "80") ? "" : (":".$_SERVER["SERVER_PORT"]);
# 获取的完整url
$_fullUrl = $protocol . "://" . $_SERVER['SERVER_NAME'] . $port . $requestUri;

$staticDir = 'static/';

if(is_mobile()) {
$suffix = 'mobile';
} else {
$suffix = 'pc';
}
$fileDir = $staticDir.md5($_fullUrl).'_'.$suffix.'.html';

//如果生成静态文件在1小时内,直接使用静态文件,否重新生成

if (file_exists ( $fileDir ) && time () - filectime ( $fileDir ) < 3600) {

include $fileDir;
} else {
ob_start ();
if(file_exists ( $fileDir ))unlink($fileDir);
define ( 'WP_USE_THEMES', true );
/**
* Loads the WordPress Environment and Template
*/
require (dirname ( __FILE__ ) . '/wp-blog-header.php');
$html = ob_get_contents ();
$path = $fileDir;
$fp = fopen($path,"w+");
flock($fp, LOCK_EX) ;
fwrite($fp,$html);
flock($fp, LOCK_UN);
fclose($fp);
}
