PHP压缩html网页代码 (清除空格,换行符,制表符,注释标记)。 
有个不错的方法就是压缩HTML,压缩html 其实就是:清除换行符,清除制表符,去掉注释标记 。它所起到的作用不可小视。 
现提供PHP 压缩HTML函数。请大家不妨试试看,感觉还不错吧。 

不废话了,直接上代码: 

<?php 
/** 
* 压缩html : 清除换行符,清除制表符,去掉注释标记 
* @param $string 
* @return 压缩后的$string 
* */ 
function compress_html($string) { 
$string = str_replace("\r\n", &#39;&#39;, $string); //清除换行符 
$string = str_replace("\n", &#39;&#39;, $string); //清除换行符 
$string = str_replace("\t", &#39;&#39;, $string); //清除制表符 
$pattern = array ( 
"/> *([^ ]*) *</", //去掉注释标记 
"/[\s]+/", 
"/<!--[^!]*-->/", 
"/\" /", 
"/ \"/", 
"&#39;/\*[^*]*\*/&#39;" 
); 
$replace = array ( 
">\\1<", 
" ", 
"", 
"\"", 
"\"", 
"" 
); 
return preg_replace($pattern, $replace, $string); 
} 
?>
