PHP清除html标签(清除空格,换行符,制表符,注释标记)

/**
*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){
	$string=str_replace("\r\n",'',$string);//清除换行符
	$string=str_replace("\n",'',$string);//清除换行符
	$string=str_replace("\t",'',$string);//清除制表符
	$pattern=array(
		"/> *([^ ]*) *		"/[\s]+/",
		"//",
		"/\" /",
		"/ \"/",
		"'/\*[^*]*\*/'"
	);
	$replace=array(
		">\\1<",
		" ",
		"",
		"\"",
		"\"",
		""
	);
	return preg_replace($pattern,$replace,$string);
}

下面方法来实现这个想法。

思路如下：

function cleanHtml($str){ 
	$str=trim($str);
	$str=strip_tags($str,"");
	$str=ereg_replace("\t","",$str);
	$str=ereg_replace("\r\n","",$str);
	$str=ereg_replace("\r","",$str);
	$str=ereg_replace("\n","",$str);
	$str=ereg_replace(" "," ",$str);
	return trim($str);
}
