Detailed explanation of PHP WeChat custom menu interface, customer service interface, and QR code usage code

<?php

$appsecret = "ed222a84da15cd24c4bdfa5d9adbabf2";

//下面是一个cURL会话过程，通过这个会话可以返回一段字符串{"access_token":"NU7Kr6v9L9TQaqm5NE3OTPctTZx797Wxw4Snd2WL2HHBqLCiXlDVOw2l-Se0I-WmOLLniAYLAwzhbYhXNjb"}
这就是我们要获得的Access Token了。在调用高级功能接口的时候就靠它。这个过程用的时候直接引用就好，不需要深究，这个cURL系统相关函数有点多而且复杂。

$ch = curl_init();//初始化
curl_setopt($ch, CURLOPT_URL, $url);//与url建立对话
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); //进行配置
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); //进行配置
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//进行配置
$output = curl_exec($ch);//执行对话，获取接口数据Access Token
curl_close($ch);//关闭会话
$jsoninfo = json_decode($output, true);//解码接口数据，将json格式字符串转换成php变量或数组。默认是变量，加true后是数组。
$access_token = $jsoninfo["access_token"];
