php怎么清除超链接

$str=preg_replace("/]*href=[^>]*>|<\/[^a]*a[^>]*>/i","",$content);

ereg_replace("]*>|<\/a>","",$content);

$find="this string is my find"; $string='这段内容将要被替换掉';//将超链接替换成的内容 echo ereg_replace(']*)>([^<]*'.$find.'[^>]*)','\\2',$content);

//方法一 preg_match_all('/<(a|a)[s]{0,1}[w=":()]*>[nrn]*(check user)[nrn]*/i',$string,$matches); //方法二 preg_match_all('/check user/i',$string,$matches); print_r($matches); //方法三 preg_match_all('/]*>[^<]*/i',$string,$matches); print_r($matches); //方法四 preg_match_all('/check user/is',$str,$arr); print_r($arr);
