有些时候,我们需要对一些html文本进行处理,比如需要将文本中的超链接内容去除,这个时候就需要用到正则表达式了。比如你可以用$str = preg_replace("/]*href=[^>]*>|]*>/i","",$strhtml); 这段来实现需求,如果想要更多解决方法,可以参看以下的。

1、删除内容中的超链接

ereg_replace('<a([^>]*)>([^<]*)</a>','<font color="red">\\2</font>',$content);

ereg_replace("<a [^>]*>|<\/a>","",$content);
Copy after login

2、消除包含特定词的超链接

$find="this string is my find";
$string='<font color="red">替换掉了</font>';//将超链接替换成的内容
echo ereg_replace('<a([^>]*)>([^<]*'.$find.'[^>]*)</a>','<font color="red">\\2</font>',$content);
Copy after login

3、获取超链接文本内容

//方法一
preg_match_all('/<(a|a)[s]{0,1}[w=":()]*>[nrn]*(check user)[nrn]*</(a|a)>/i',$string,$matches);

//方法二
preg_match_all('/<a[dd]*>check user</a>/i',$string,$matches);
print_r($matches);

//方法三
preg_match_all('/<a[^>]*>[^<]*</a>/i',$string,$matches);
print_r($matches);

//方法四
preg_match_all('/<a.+?>check user</a>/is',$str,$arr);
print_r($arr);

//方法五
preg_match_all('/<a.+?>check user</a>/is',$str,$arr);
print_r($arr);
Copy after login
