PHP写个微信端获取用户手机号的案例

<?php
// 微信登录回调接口
function wxLoginCallback() {
    // 获取微信授权登录的code
    $code = $_GET['code'];
    
    // 根据code获取access_token
    $url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid=YOUR_APPID&secret=YOUR_APPSECRET&code=".$code."&grant_type=authorization_code";
    $response = file_get_contents($url);
    $data = json_decode($response, true);
    
    // 根据access_token获取用户手机号
    $url = "https://api.weixin.qq.com/sns/userinfo?access_token=".$data['access_token']."&openid=".$data['openid'];
    $response = file_get_contents($url);
    $userInfo = json_decode($response, true);
    
    // 输出用户手机号
    echo $userInfo['phone'];
}
?>
