**1.基本配置**

//公众账号appid  
    $data["mch_appid"] = 'appid'; 
    //商户号   
    $data["mchid"] = ''; 
    //随机字符串  
    $data["nonce_str"] = 'suiji'.mt_rand(100,999); 
    //商户订单号   
    $data["partner_trade_no"]=date('YmdHis').mt_rand(1000,9999); 
    //金额 用户输入的提现金额需要乘以100  
    $data["amount"] = $money;  
    //企业付款描述  
    $data["desc"] = '企业付款到个人零钱';  
    //用户openid     
    $data["openid"] = $openid;  
    //不检验用户姓名 
    $data["check_name"] = 'NO_CHECK';  
    //获取IP    
    $data['spbill_create_ip']=$_SERVER['SERVER_ADDR'];  
    //商户密钥   
    $data['key']=''; 
    //商户证书 商户平台的API安全证书下载 
     $data['apiclient_cert.pem']
     $data['apiclient_key.pem']

**2.PHP代码**

/**
    **开始支付
    /
     public function userpay(){
     $money = ‘用户输入提现金额';
     $info['money'] = ‘用户余额';
     if ($this->openid && $money){
      if ($money>$info['money'] ){
      echo json_encode([
       'status' => 1,
       'message' => '余额不足，不能提现！',
       'code'=>'余额不足，不能提现！'   ]);
      }elseif ($money<1){
      echo json_encode([
       'status' => 2,
       'message' => '提现金额不能小于1元',
       'code'=>'提现金额太低'   ]);
      }else{
     $openid = $this->openid;
     $trade_no = date('YmdHis').mt_rand(1000,9999);
     $res = $this->pay($openid,$trade_no,$money*100,'微信提现');
    
     //结果打印
     if($res['result_code']=="SUCCESS"){
    
       echo json_encode([
       'status' => 3,
       'message' => '提现成功！',
       ]);
      }elseif ($res['err_code']=="SENDNUM_LIMIT"){
       echo json_encode([
       'status' => 4,
       'message' => '提现失败！',
       'code'=>'每日仅能提现一次',
       ]);
      }else{
       echo json_encode([
       'status' => 5,
       'message' => '提现失败！',
       'code'=>$res['err_code'],
       ]);
      }
      }
     }else{
      echo json_encode([
      'status' => 5,
      'message' => '未检测到您当前微信账号~',
    
      ]);
     }
     }

支付方法

生成签名
