Loops Paypal IPN 1.1 php脚本似乎循环了好几次

我最近更新了新1.1版本的IPN脚本。它可以工作，付款也可以通过，但它多次运行我的成功代码（插入数据库，发送电子邮件）。e、 我做了一次试购，我的订单通过了22次，我收到了22封电子邮件

这是我的确切代码（实际的数据库和邮件代码是直接的-根本没有循环）：

我就是这样做的：

$arrRequestVars=$_POST;

$cx=stream_context_create(
    array(
        "http"=>array(
            "method"=>"POST",
            "header"=>"Content-type: application/x-www-form-urlencoded",
            "content"=>"cmd=_notify-validate&".http_build_query($arrRequestVars),
        ),
        "tls"=>array(
            "allow_self_signed"=>false,
        ),
        "ssl"=>array(
            "allow_self_signed"=>false,
        ),
    )
);
$strPayPalVerifyResponse=file_get_contents("https://".PAYPAL_API_HOSTNAME."/cgi-bin/webscr", false, $cx);
if(is_string($strPayPalVerifyResponse))
{
    $_arrParts=explode(" ", $http_response_header[0]);
    $nHTTPResponseCode=(int)$_arrParts[1];
    if($nHTTPResponseCode!==200)
        throw new Exception("Failed to verify wether request originated from PayPal. HTTP response code: ".$nHTTPResponseCode);

    if(trim($strPayPalVerifyResponse)=="INVALID")
        throw new Exception("PayPal did not recognize/validate the incoming IPN request. If the request was valid then mark as paid manually.");
    else if(trim($strPayPalVerifyResponse)!="VERIFIED")
        throw new Exception("Failed to verify wether request originated from PayPal. PayPal response: ".$strPayPalVerifyResponse);
}
else
    throw new Exception("Failed to verify wether request originated from PayPal.");

这是一个尽可能少的依赖关系示例。我建议对文件内容进行卷曲。

再多加一点最佳做法格式化，你可能会自己看到问题。好的……我现在觉得格式还可以（我缩进了}）。我仍然看不出问题所在，尽管它必须是while（）循环一次又一次地运行，但我不明白为什么它会运行不止一次？这与大多数人在脚本顶部使用的try error_reporting（-1）代码相同，请查看您发现了什么。

$arrRequestVars=$_POST;

$cx=stream_context_create(
    array(
        "http"=>array(
            "method"=>"POST",
            "header"=>"Content-type: application/x-www-form-urlencoded",
            "content"=>"cmd=_notify-validate&".http_build_query($arrRequestVars),
        ),
        "tls"=>array(
            "allow_self_signed"=>false,
        ),
        "ssl"=>array(
            "allow_self_signed"=>false,
        ),
    )
);
$strPayPalVerifyResponse=file_get_contents("https://".PAYPAL_API_HOSTNAME."/cgi-bin/webscr", false, $cx);
if(is_string($strPayPalVerifyResponse))
{
    $_arrParts=explode(" ", $http_response_header[0]);
    $nHTTPResponseCode=(int)$_arrParts[1];
    if($nHTTPResponseCode!==200)
        throw new Exception("Failed to verify wether request originated from PayPal. HTTP response code: ".$nHTTPResponseCode);

    if(trim($strPayPalVerifyResponse)=="INVALID")
        throw new Exception("PayPal did not recognize/validate the incoming IPN request. If the request was valid then mark as paid manually.");
    else if(trim($strPayPalVerifyResponse)!="VERIFIED")
        throw new Exception("Failed to verify wether request originated from PayPal. PayPal response: ".$strPayPalVerifyResponse);
}
else
    throw new Exception("Failed to verify wether request originated from PayPal.");
