想将链接A的红色的部分换成链接B红色对应的部分,怎么弄啊。谢谢~~

------解决方案--------------------
uin 和 blogid 原来都应该是数值吧? 还是你的xxxx yyyy?
PHP code
$str1 = "http://user.qzone.qq.com/1340477530#!app=2&pos=1300412602";$str2 = "http://b.qzone.qq.com/cgi-bin/blognew/blog_output_data?uin=1111&blogid=2222&numperpage=1000&";preg_match('/([\d]+).*pos=([\d]+)$/', $str1, $match);if (isset($match[1]) && isset($match[2])) {    $pa=array('/uin=[\d]+/','/blogid=[\d]+/');    $re=array('uin='.$match[1],'blogid='.$match[2]);    $str2=preg_replace($pa,$re,$str2);    echo $str2;}<div class="clear">
                 
              
              
        
            </div>
Copy after login
