作为站长或者是开发者,应该都了解到CSS是决定页面视觉效果的一个魔法文件。而为了让页面效果更给力,我们往往需要写很多的CSS代码。CSS一多,网页加载的速度就会变慢下来。所以呢,减小CSS文件的大小就是一个必须的事情了。而压缩就是最常见的一种给CSS文件减肥的方法。下面,我们就来看看如何通过PHP给CSS代码减肥:

<?php header(&#8216;Content-type: text/css&#8217;);   
ob_start(&#8220;compress&#8221;);   
function compress($buffer) {   
$buffer = preg_replace(&#8216;!/\*[^*]*\*+([^/][^*]*\*+)*/!&#8217;, &#8221;, $buffer);   
$buffer = str_replace(array(&#8220;\r\n&#8221;, &#8220;\r&#8221;, &#8220;\n&#8221;, &#8220;\t&#8221;, &#8217; &#8217;, &#8217; &#8217;, &#8217; &#8217;), &#8221;, $buffer);   
return $buffer;   
}   
include(&#8216;master.css&#8217;);   
include(&#8216;typography.css&#8217;);   
include(&#8216;grid.css&#8217;);   
include(&#8216;print.css&#8217;);   
include(&#8216;handheld.css&#8217;);   
ob_end_flush();
