一般处理的方式有二种：1.通过编辑器的JS直接去除。2.提交到后台后，直接用程序去掉无效标签。下面我就分享一个通过PHP的处理方式，成功率可能不是100%。这程序也是在PHP官网上看到的，就顺便粘贴过来了。
<div class="codetitle"><a style="CURSOR: pointer" data="93041" class="copybut" id="copybut93041" onclick="doCopy('code93041')"> 代码如下:<div class="codebody" id="code93041">
function ClearHtml($content,$allowtags='') { mb_regex_encoding('UTF-8');
//replace MS special characters first
$search = array('/‘/u','/’/u','/“/u','/”/u','/—/u');
$replace = array(''',''','"','-');
$content = preg_replace($search,$replace,$content);
//make sure all html entities are converted to the plain ascii equivalents - it appears
//in some MS headers,some html entities are encoded and some aren't
$content = html_entity_decode($content,ENT_QUOTES,'UTF-8');
//try to strip out any C style comments first,since these,embedded in html comments,seem to
//prevent strip_tags from removing html comments (MS Word introduced combination)
if(mb_stripos($content,'/') !== FALSE){
$content = mb_eregi_replace('#/*.?*/#s','',$content,'m');
}
//introduce a space into any arithmetic expressions that could be caught by strip_tags so that they won't be
//'<1' becomes '< 1'(note: somewhat application specific)
$content = preg_replace(array('/<([0-9]+)/'),array('< $1'),$content); $content = strip_tags($content,$allowtags);
//eliminate extraneous whitespace from start and end of line,or anywhere there are two or more spaces,convert it to one
$content = preg_replace(array('/^ss+/','/ss+$/','/ss+/u'),array('',' '),$content);
//strip out inline css and simplify style tags
$search = array('#<(h3|b)[^>]>(.?)</(h3|b)>#isu','#<(em|i)[^>]>(.?)</(em|i)>#isu','#<u[^>]>(.?)#isu');
$replace = array('$2','$2','$1');
$content = preg_replace($search,$content); //on some of the ?newer MS Word exports,where you get conditionals of the form 'if gte mso 9',etc.,it appears
//that whatever is in one of the html comments prevents strip_tags from eradicating the html comment that contains
//some MS Style Definitions - this last bit gets rid of any leftover comments /
$num_matches = preg_match_all("/&;!--/u",$matches);
if($num_matches){
$content = preg_replace('/&;!--(.)-->/isu',$content);
}
return $content;
}
测试使用结果：
<div class="codetitle"><a style="CURSOR: pointer" data="84755" class="copybut" id="copybut84755" onclick="doCopy('code84755')"> 代码如下:<div class="codebody" id="code84755">
<?php
$content = '
<p class="p0" style="text-indent: 24.0000pt; margin-bottom: 0pt; margin-top: 0pt;"><span style="mso-spacerun: "yes"; font-size: 12.0000pt; font-family: "宋体";">《优伴户外旅行》——让旅行成为习惯！ 越发忙碌的你，是否想给自己放个假？专注工作的你，是否还记得上一次锻炼是什么时候？优伴户外旅行，给你不一样的旅行体验：给心自由，便处处都是风景！';
echo ClearHtml($content,''); /
得到的结果：
