通常我们会遇到直接把word内的内容，直接粘贴到文本编辑器中。这时候会出现在文本编辑器中有一些word内的没用的标签内容。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。

 

 

1 function ClearHtml($content,$allowtags='') { 2              3             mb_regex_encoding('UTF-8'); 4             //replace MS special characters first 5             $search = array('/‘/u', '/’/u', '/“/u', '/”/u', '/—/u'); 6             $replace = array('\'', '\'', '"', '"', '-'); 7             $content = preg_replace($search, $replace, $content); 8             //make sure _all_ html entities are converted to the plain ascii equivalents - it appears 9             //in some MS headers, some html entities are encoded and some aren't10             $content = html_entity_decode($content, ENT_QUOTES, 'UTF-8');11             //try to strip out any C style comments first, since these, embedded in html comments, seem to12             //prevent strip_tags from removing html comments (MS Word introduced combination)13             if(mb_stripos($content, '/*') !== FALSE){14                 $content = mb_eregi_replace('#/\*.*?\*/#s', '', $content, 'm');15             }16             //introduce a space into any arithmetic expressions that could be caught by strip_tags so that they won't be17             //'<1' becomes '< 1'(note: somewhat application specific)18             $content = preg_replace(array('/<([0-9]+)/'), array('< $1'), $content);19             20             $content = strip_tags($content, $allowtags);21             //eliminate extraneous whitespace from start and end of line, or anywhere there are two or more spaces, convert it to one22             $content = preg_replace(array('/^\s\s+/', '/\s\s+$/', '/\s\s+/u'), array('', '', ' '), $content);23             //strip out inline css and simplify style tags24             $search = array('#<(strong|b)[^>]*>(.*?)
        #isu', '#<(em|i)[^>]*>(.*?)
        #isu', '#
        
         ]*>(.*?)#isu');25             $replace = array('
         $2', '
         $2', '
         $1');26             $content = preg_replace($search, $replace, $content);27             28             //on some of the ?newer MS Word exports, where you get conditionals of the form 'if gte mso 9', etc., it appears29             //that whatever is in one of the html comments prevents strip_tags from eradicating the html comment that contains30             //some MS Style Definitions - this last bit gets rid of any leftover comments */31             $num_matches = preg_match_all("/\
