php如何使用正则去掉html属性

php使用正则去掉html的方法：首先创建一个PHP示例文件；然后通过正则表达式“preg_replace("/<([a-za-z] )[^>]*>/","<\\\\\\\\1>",$html);”过滤所有html标签的属性即可。

php过滤HTML标签、属性等正则表达式汇总

$str=preg_replace("/\\\\s /", " ", $str); //过滤多余回车
$str=preg_replace("/<[ ] /si","<",$str); //过滤<__("<"号后面带空格)
   
$str=preg_replace("/<\\\\!--.*?-->/si","",$str); //注释
$str=preg_replace("/<(\\\\!.*?)>/si","",$str); //过滤DOCTYPE
$str=preg_replace("/<(\\\\/?html.*?)>/si","",$str); //过滤html标签
$str=preg_replace("/<(\\\\/?head.*?)>/si","",$str); //过滤head标签
$str=preg_replace("/<(\\\\/?meta.*?)>/si","",$str); //过滤meta标签
$str=preg_replace("/<(\\\\/?body.*?)>/si","",$str); //过滤body标签
$str=preg_replace("/<(\\\\/?link.*?)>/si","",$str); //过滤link标签
$str=preg_replace("/<(\\\\/?form.*?)>/si","",$str); //过滤form标签
$str=preg_replace("/cookie/si","COOKIE",$str); //过滤COOKIE标签
   
$str=preg_replace("/<(applet.*?)>(.*?)<(\\\\/applet.*?)>/si","",$str); //过滤applet标签
$str=preg_replace("/<(\\\\/?applet.*?)>/si","",$str); //过滤applet标签
   
$str=preg_replace("/<(style.*?)>(.*?)<(\\\\/style.*?)>/si","",$str); //过滤style标签
$str=preg_replace("/<(\\\\/?style.*?)>/si","",$str); //过滤style标签
   
$str=preg_replace("/<(title.*?)>(.*?)<(\\\\/title.*?)>/si","",$str); //过滤title标签
$str=preg_replace("/<(\\\\/?title.*?)>/si","",$str); //过滤title标签
   
$str=preg_replace("/<(object.*?)>(.*?)<(\\\\/object.*?)>/si","",$str); //过滤object标签
$str=preg_replace("/<(\\\\/?objec.*?)>/si","",$str); //过滤object标签
   
$str=preg_replace("/<(noframes.*?)>(.*?)<(\\\\/noframes.*?)>/si","",$str); //过滤noframes标签
$str=preg_replace("/<(\\\\/?noframes.*?)>/si","",$str); //过滤noframes标签
   
$str=preg_replace("/<(i?frame.*?)>(.*?)<(\\\\/i?frame.*?)>/si","",$str); //过滤frame标签
$str=preg_replace("/<(\\\\/?i?frame.*?)>/si","",$str); //过滤frame标签
   
$str=preg_replace("/<(script.*?)>(.*?)<(\\\\/script.*?)>/si","",$str); //过滤script标签
$str=preg_replace("/<(\\\\/?script.*?)>/si","",$str); //过滤script标签
$str=preg_replace("/javascript/si","Javascript",$str); //过滤script标签
$str=preg_replace("/vbscript/si","Vbscript",$str); //过滤script标签
$str=preg_replace("/on([a-z] )\\\\s*=/si","On\\\\\\\\1=",$str); //过滤script标签
$str=preg_replace("/&#/si","&＃",$str); //过滤script标签，如javAsCript:alert(

清除空格，换行

function DeleteHtml($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);
}

过滤HTML属性

1，过滤所有html标签的正则表达式：

</?[^>] >
  
//过滤所有html标签的属性的正则表达式：
  
$html = preg_replace("/<([a-zA-Z] )[^>]*>/","<\\\\\\\\1>",$html);
