';

preg_match_all("/http:[＼/]{2}[a-z]+[.]{1}[a-z＼d＼-]+[.]{1}[a-z＼d]*[＼/]*[A-Za-z＼d]*[＼/]*[A-Za-z＼d]*/",$postInfo['answer2'],$array2);

print_r($array2);

{
 foreach ($array2[0] as $k=>$v){

结果就为

)

{
header("HTTP/1.1 301 Moved Permanently");//发出301头部
header("Location:111cn.net) //跳转到你希望的域名
exit();
}

<?php
$the_host = $_SERVER['HTTP_HOST'];//取得当前域名
$the_url = isset($_SERVER['REQUEST_URI']) ? $_SERVER['REQUEST_URI'] : '';//判断地址后面部分
$the_url = strtolower($the_url);//将英文字母转成小写
if($the_url=="/index.php")//判断是不是首页
{
$the_url="";//如果是首页，赋值为空
}
if($the_host !== 'www.111cn.net ')//如果域名不是带www的网址那么进行下面的301跳转
{
header('HTTP/1.1 301 Moved Permanently');//发出301头部
header('Location:http://www.111cn.net '.$the_url);//跳转到带www的网址
