首先将所有 CSS 放到一个目录里，然后在此目录新建一个空的 CSS 文件，命名为 css.php（其实除了后缀命名随便）。
然后在 PHP 文件里放下边的代码：
| 代码如下 | 复制代码 |
|
<?php header('Content-type: text/css'); ob_start("compress"); function compress($buffer) { $buffer = preg_replace('!/*[^*]**+([^/][^*]**+)*/!', '', $buffer); $buffer = str_replace(array("rn", "r", "n", "t", ' ', ' ', ' '), '', $buffer); return $buffer; } /*include('colorpicker.css'); include('jquery-ui.css'); include('style.css'); include('switchery.min.css');*/ foreach( glob( "*.css" ) as $filename ) include $filename; ob_end_flush(); 引入 CSS 文件的代码换成引入这个 PHP 文件，例如： <link rel='stylesheet' id='style-css' href='/css/css.php' type='text/css' media='all' /> |
|
压缩多个css为一个css
| 代码如下 | 复制代码 |
|
<?php /* Compress multiple CSS files into one and cache for an hour. Use the same code for Javascript, but replace below "text/css" with "text/javascript" and of course make sure you include .js files instead of .css ones. include('somefile.css'); ob_flush(); |
|
下面整理可压缩css,js的函数
| 代码如下 | 复制代码 |
|
/** * 合并css样式为一个文件 * * @param unknown_type $urls * @param unknown_type $path * @param unknown_type $tmpl_path * @return unknown */ function parse_css($urls,$path="./static/",$tmpl_path='.'){ $url = md5(implode(',',$urls)); $css_url = $path.$url.'.css'; if(!file_exists($css_url)){ if(!file_exists($path))mkdir($path,0777); $css_content = ''; foreach($urls as $url){ $css_content .= @file_get_contents($url); } $css_content = preg_replace("/[rn]/",'',$css_content); $css_content = str_replace("../images/",$tmpl_path."/images/",$css_content); @file_put_contents($css_url,$css_content); } return $css_url; } /** * 合并js www.111cn.net为一个文件 * * @param unknown_type $urls * @param unknown_type $path * @return unknown */ function parse_script($urls,$path="./static/"){ $url = md5(implode(',',$urls)); $js_url = $path.$url.'.js'; if(!file_exists($js_url)) { if(!file_exists($path))mkdir($path,0777); require_once "inc/javascriptpacker.php"; $js_content = ''; foreach($urls as $url) { $append_content = @file_get_contents($url)."rn"; $packer = new JavaScriptPacker($append_content); $append_content = $packer->pack(); $js_content .= $append_content; } @file_put_contents($js_url,$js_content); } return $js_url; } 前台 js调用 <?php $pagejs[] = $tplurl."js/jump.js"; $jsfile=parse_script($pagejs,"./template/default/js/","."); ?> <script type="text/javascript" src="<?=$jsfile?>"></script> css调用 <?php $pagecss[] = $tplurl."style/index_top.css"; $pagecss[] = $tplurl."style/index.css"; $cssfile=parse_css($pagecss,"./template/default/style/","."); ?> <link rel="stylesheet" type="text/css" href="<?=$cssfile?>" /> |
|
PHP 文件里就包含了所有被压缩的 CSS 代码，而且可以自动引入 CSS 目录里的所有 CSS 文件，不用在新建 CSS 文件的时候再修改这个 PHP 文件。
