PHP 改如何提取这个 openid 值

This topic created in 4301 days ago, the information mentioned may be changed or developed.

如题.
QQ登录返回的包是这样的：callback( {"client_id":"YOUR_APPID","openid":"YOUR_OPENID"} );

我想要用其中的openid，有什么好办法可以提取出来么？

openid

callback

提取

<?php
$str = 'callback({"client_id":"YOUR_APPID","openid":"YOUR_OPENID"});';
$lpos = strpos($str, "(");
$rpos = strrpos($str, ")");
$str = substr($str, $lpos+1, $rpos-$lpos-1);
$json = json_decode($str);
// print_r($json);
$openid = $json->openid;
echo $openid;

这个其实是qq准备让你用js来运行的...

```php
$callback = 'callback( {"client_id":"YOUR_APPID","openid":"YOUR_OPENID"} )';
if (preg_match('/\"openid\":\"(\w+)\"/i', $callback, $match)) {
$openid = $match[1];
}
var_dump($openid);exit;
```
略菜...勿喷
