替换源码中获取后的URL的问题！
$url = "http://www.baidu.com";
$newurl = "http://www.163.com";

$contents = file_get_contents($url);
echo preg_replace('/href="(.+?)"/i','href="http://'.rand(100,999).'"',$contents);

我原本是想把源码中的连接都随机不同替换，现在就是所有的连接都替换成了一个随机！请问怎么解决？

------解决方案--------------------

$contents = <<< TXT<br />href="http://www.baidu.com"<br />href="http://www.163.com"<br />TXT;<br /><br />echo preg_replace('/href="(.+?)"/ise', '"href=\"http://".rand(100,999)."\""',$contents);

Copy after login

href="http://217"
href="http://562"
