php - 处理从 cURL 输出的数据

Question

$res verbal 中的以下数据是 cURL 的输出，我正尝试使用它来使以下脚本正常工作。但它根本不处理数据。我检查过它的第一行是 $lines[0] 中的 SUCCESS。它应该输出其余的数据，但它没有。任何人都对如何解决这个问题有任何想法。或者是因为我没有通过 cURL 处理数据来测试它。在我上线之前，我要如何使脚本完美运行。 cURL pules 来自 PayPal 的数据作为 pdt，而 PayPals 沙箱是垃圾

$res = "SUCCESS

    $keyarray = array();
    if (strcmp ($lines[0], "SUCCESS") == 0) {
        for ($i=1; $i<count($lines);$i++){
        list($key,$val) = explode("=", $lines[$i]);
        $keyarray[urldecode($key)] = urldecode($val);

    }

    $firstname = $keyarray['first_name'];
    $lastname = $keyarray['last_name'];
    $itemname = $keyarray['item_name'];
    $amount = $keyarray['payment_gross'];

    echo ("<p><h3>Thank you for your purchase!</h3></p>");

    echo ("<b>Payment Details</b><br>\n");

    echo ("<li>Item: $itemname</li>\n");
    echo ("<li>Amount: $amount</li>\n");
    echo ("");
    }
    else if (strcmp ($lines[0], "FAIL") == 0) {
        echo(' log for manual investigation');
    }
}

这是一个已知的 paypal 问题，您需要像这样从第一个响应行中删除一些空格:

if (strcmp (trim($lines[0]), "SUCCESS") == 0) {
