PHP提取Json当中的几个数据！50分求解答 高手来帮忙下！

网址例如：http://123456.com/Ashx/actForm.ashx?action=addorder&gameid=65&num=10&realname=小梦&UserEmail=xiaomeng@qq.com&SearchPass=123654
提交以后的显示是 {"types":"OK","msg":"17961_14102404200616788"} 
我想用PHP直接调用出 _ 以后的数字 14102404200616788   
不知道怎么实现，本人新手，不太懂  百度了半天！

回复讨论(解决方案)

$s = '{"types":"OK","msg":"17961_14102404200616788"}';
echo explode('_', json_decode($s)->msg)[1];

$s = '{"types":"OK","msg":"17961_14102404200616788"}';
echo explode('_', json_decode($s)->msg)[1];

//$result = file_get_contents('http://123456.com/Ashx/actForm.ashx?action=addorder&gameid=65&num=10&realname=小梦&UserEmail=xiaomeng@qq.com&SearchPass=123654');$result = '{"types":"OK","msg":"17961_14102404200616788"}';$json = json_decode($result,true);$id = explode('_',$json['msg']);echo $id[1];

{"types":"OK","msg":"17961_14102404200616788"} 但是 他每次这个 生成 都不一样哇 ！！！

例如
{"types":"OK","msg":"17961_14102404200616788"}
{"types":"OK","msg":"17962_14102453453453453"}
{"types":"OK","msg":"17963_14102534534534535"}
{"types":"OK","msg":"17964_14102534534534534"}
打开一次 他生成一次哇！

每次不一样有什么问题呢，处理方法都一样。

 $result = array(     '{"types":"OK","msg":"17961_14102404200616788"}',     '{"types":"OK","msg":"17962_14102453453453453"}',     '{"types":"OK","msg":"17963_14102534534534535"}',     '{"types":"OK","msg":"17964_14102534534534534"}' );foreach($result as $v){    echo getdata($v).'
';}function getdata($str){    $data = json_decode($str, true);    list($id, $timestamp) = explode('_', $data['msg']);    return $timestamp;}

现在调用出来了 接下来 要怎么把 14102404200616788 Json 调用到 JS那边去 例如别人网站 显示

正在跳转页面... ...
