php实现支付接口例子

<?php
// 支付请求函数
function requestPayment($amount, $currency, $description) {
    $url = "https://api.paymentgateway.com/pay";
    $data = [
        'amount' => $amount,
        'currency' => $currency,
        'description' => $description,
        'token' => 'your_payment_token'
    ];

    $options = [
        'http' => [
            'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
            'method'  => 'POST',
            'content' => http_build_query($data),
        ],
    ];

    $context  = stream_context_create($options);
    $result = file_get_contents($url, false, $context);
    if ($result === FALSE) { /* Handle error */ }

    return json_decode($result);
}

// 处理支付结果
function handlePaymentResult($result) {
    if ($result->status == 'success') {
        echo "Payment successful!";
    } else {
        echo "Payment failed: " . $result->message;
    }
}

// 示例调用
$amount = 100.00;
$currency = 'USD';
$description = 'Test payment';

$result = requestPayment($amount, $currency, $description);
handlePaymentResult($result);
?>
