分享一种利用 php 清除html代码中的空格,换行符,制表符,注释标记等以达到压缩输出 html 的目的。

<p>/**</p>*压缩html:清除换行符,清除制表符,去掉注释标记<br />*@param $string<br />*@return 压缩后的$string<br />**/<br />function compress_html($string){<br />	$string=str_replace("\r\n",'',$string);//清除换行符<br />	$string=str_replace("\n",'',$string);//清除换行符<br />	$string=str_replace("\t",'',$string);//清除制表符<br />	$pattern=array(<br />		"/> *([^ ]*) *</",//去掉注释标记 <br />		"/[\s]+/",<br />		"/<!--[^!]*-->/",<br />		"/\" /",<br />		"/ \"/",<br />		"'/\*[^*]*\*/'"<br />	);<br />	$replace=array(<br />		">\\1<",<br />		" ",<br />		"",<br />		"\"",<br />		"\"",<br />		""<br />	);<br />	return preg_replace($pattern,$replace,$string);<br /><p>}

下面方法来实现这个想法。

思路如下:

<p>function cleanHtml($str){ </p>	$str=trim($str);<br />	$str=strip_tags($str,"");<br />	$str=ereg_replace("\t","",$str);<br />	$str=ereg_replace("\r\n","",$str);<br />	$str=ereg_replace("\r","",$str);<br />	$str=ereg_replace("\n","",$str);<br />	$str=ereg_replace(" "," ",$str);<br />	return trim($str);<br />}
Copy after login
