在下面的代码中，变量$filedownload应该是一个链接。当在文件夹外调用时，它不会显示。当我在singleuse文件夹中执行类似的脚本并从include代码中更改remove文件夹时，它就会显示出来。我想可能是todo和include通话？我想从文件夹外部调用该变量。
我测试了这个变量，它有一个值。它只是没有出现在电子邮件中。
<?php
/**
* This file creates the single use download link
* The query string should be the password (which is set in variables.php)
* If the password fails, then 404 is rendered
*
* Expects: generate.php?1234
*/
include("variables.php");
// Grab the query string as a password
$password = '1234';
/*
* Verify the admin password (in variables.php)
*/
if($password == ADMIN_PASSWORD) {
// Create a new key
$new = uniqid('key',TRUE);
/*
* Create a protected directory to store keys in
*/
if(!is_dir('keys')) {
mkdir('keys');
$file = fopen('keys/.htaccess','w');
fwrite($file,"Order allow,deny'nDeny from all");
fclose($file);
}
/*
* Write the key key to the keys list
*/
$file = fopen('keys/keys','a');
fwrite($file,"{$new}'n");
fclose($file);

$mail_From = "From: me@mybiz.com";
$mail_To = "savisaar2@gmail.com";
$mail_Subject = "VERIFIED IPN";
$mail_Body = "Hello there, thank you for purchasing from us. 'nPlease go to: " . $filedownload;
mail($mail_To, $mail_Subject, "'n'n" . $mail_Body, $mail_From);
在最后一次尝试中，我决定尝试使用不同的php脚本来处理电子邮件，结果成功了！
if ($payment_status == 'Completed') {
include('singleuse/generate.php');
$to = 'savisaar2@gmail.com';
$subject = 'Transation Completed [Ref #' . $txn_id . ']';
$message = 'Thank you ' . $payer_email . '! Your payment status is: ' . $payment_status . ', your order number is #' . $txn_id . '. Please follow this link to get your download: ' . $filedownload;
$headers = 'From: webmaster@dev4you.hints.me' . "'r'n" .
'Reply-To: webmaster@dev4you.hints.me' . "'r'n" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);
