Connect with QQ interface to realize PHP online payment function

With the development of the Internet, e-commerce has become a common business model. As one of the core components of e-commerce, online payment's security and convenience are very important to both merchants and consumers. This article will introduce how to implement the online payment function in the PHP website by docking with the QQ interface.

1. Apply for the QQ payment interface

First, we need to apply for the QQ payment interface on the QQ merchant platform. The specific steps are as follows:

1. Log in to the QQ merchant platform and click the "Web Payment" option on the left menu.
2. Click the "Apply for Payment" button and fill in the relevant information according to the prompts, including merchant name, business person in charge, contact person, etc.
3. After submitting the application, wait for review. Under normal circumstances, after passing the review, you will receive the "merchant number" and "key" sent by the QQ merchant platform.

2. Write PHP code

1. First, we need to create a PHP file as a callback page for receiving payment results, named "notify.php". The code example is as follows:

<?php
//获取支付结果
$payment_result = file_get_contents("php://input");
//根据实际情况对支付结果进行处理
//...
?>

2. Next, we need to create a page for initiating payment requests, named "pay.php". The code example is as follows:

<?php
//配置商户号和密钥
$merchant_id = "商户号";
$merchant_key = "密钥";

//收集订单信息
$pay_amount = $_POST['amount']; //订单金额
$pay_sn = $_POST['sn']; //订单编号

//生成签名
$sign = md5($pay_sn . $pay_amount . $merchant_key);

//拼接支付请求参数
$params = array(
    'merchant_id' => $merchant_id,
    'pay_amount' => $pay_amount,
    'pay_sn' => $pay_sn,
    'sign' => $sign
);

//构建支付请求链接
$pay_url = "https://qqpay.qq.com/cgi-bin/pay/qpay_unified_order.cgi?" . http_build_query($params);

//跳转到支付页面
header("Location: $pay_url");
?>

3. Test the payment function

1. Create a test order on the merchant platform and obtain the order number.
2. Add a payment button to the PHP website. When the button is clicked, it will jump to the "pay.php" page and pass the order amount and number as parameters.

<form action="pay.php" method="post">
    <input type="hidden" name="amount" value="订单金额">
    <input type="hidden" name="sn" value="订单编号">
    <input type="submit" value="支付">
</form>

3. Parse the payment results in the "notify.php" page and perform corresponding processing based on the actual situation.
