php提取字符串中网站url地址程序代码

$postInfo['answer2'] ='可以的，商业贷款可摊还36%，公积金贷款可摊还16%|||可以先把账户里的余额提取出来用作首付，然后每个月贷款商业贷款可摊还36%，公积金贷款可摊还16%|||可以的，现在甲类公积金是摊还比例http://www.111cn.net是工资基数的34%|||啊啊啊啊啊啊啊啊是的|||可以摊还，甲类34%
';

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);
 
if(!empty($array2[0]))
{
 foreach ($array2[0] as $k=>$v){
  $postInfo['answer2'] = str_replace($array2[0][$k],'',$postInfo['answer2'] );
 }
}

结果就为

(
    [0] => Array
        (
            [0] => http://www.111cn.net
        )

)
