基础接口的ACCESS_TOKEN就不能正常获取

我重置了APPsecret后，基础接口的ACCESS_TOKEN就不能正常获取了，只能在调试接口调出。程序如下：

<?php

$appid = “****************”;

$appsecret = “****************”;

$url = “https://api.weixin.qq.com/cgi-bin/token?grant\_type=client\_credential&amp;appid=$appid&amp;secret=$appsecret”;

$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, $url);

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 

curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); 

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$output = curl_exec($ch);

curl_close($ch);

$jsoninfo = json_decode($output, true);

$access_token = $jsoninfo[“access_token”];

echo $access_token;

?>

始终获取不了，请各位大神救救！
