【问题描述】：
我正在做一场噩梦，试图让 Paypal IPN 侦听器正常工作。到目前为止我的代码如下（请原谅冗长的代码帖子）：
require_once('../Connections/dpp.php');
mysql_select_db($database_dpp, $dpp);
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
if (PHP_VERSION < 6) {
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
}
$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}
// read the post from PayPal system and add 'cmd'
$req = 'cmd=_notify-validate';
foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}
// post back to PayPal system to validate
$header = "POST /cgi-bin/webscr HTTP/1.0\r\n";

奇怪的是，如果我在本地运行这个脚本，在 URL 中传递 POST 的内容并作为 GET 进行处理，它就可以正常工作。我只能假设代码中存在问题，但我看不到它，并且尽管我尝试调试处理（通过将数据和变量值作为战略点写入数据库），但我无法让它工作。它到达了大约四分之三的位置，并且似乎停止执行（如上面代码中的注释所示）。我知道它不会执行以下行，不管它是什么。
这是基于从 paypaltech.com 脚本生成器抓取的脚本，所以我有点希望它可以很容易地工作。
谁能看出我做错了什么？
【问题讨论】：
-
较小的非明显错误：PHP 中的
'0' == ''，因此您的代码会将合法的零转换为空值。您需要使用严格的比较运算符（!==和===）来检查空字符串。 -
好地方，虽然这不会导致我遇到的问题......
-
没有。我建议在事情似乎死去的地方吐出你正在构建的查询的文本，以及一些
echo 'got to stage XXX'类型的调用，这样你就可以准确地看到事情在哪里死去。 -
是的，我就是这么想的。由于该脚本由 PHP 调用并且从未在前端呈现，因此我一直在相关点将内容写入数据库。我在
$strQueryCart =行之后直接添加了一行来执行此操作，并且它永远不会被执行。这是我想不通的…… -
虽然在
$strQueryCart =行之前执行完全相同的语句确实执行 - 去看看！
