导读：我正在尝试将文件上传到基于IIS的服务器.这是我的代码： ?phperror_reporting(E_ALL);ini_set('display_errors','1');//ini_set('error_log','/httpdocs/error_log');echo "upload_max_filesize: " . ini_get ("upload_max_filesize"). "br";echo "post_max_

我正在尝试将文件上传到基于IIS的服务器.这是我的代码：

<?php
error_reporting(E_ALL);
ini_set('display_errors','1');
//ini_set('error_log','/httpdocs/error_log');
echo "upload_max_filesize: " . ini_get ("upload_max_filesize"). "<br>";
echo "post_max_size: " . ini_get ("post_max_size"). "<br>";
echo "memory_limit: " . ini_get ("memory_limit"). "<br>";
echo "max_file_uploads: " . ini_get ("max_file_uploads"). "<br>";
echo "max_execution_time: " . ini_get ("max_execution_time"). "<br>";
echo "max_input_time: " . ini_get ("max_input_time"). "<br>";
echo "file_uploads: " . ini_get ("file_uploads"). "<br>";
echo "default_socket_timeout: " . ini_get ("default_socket_timeout"). "<br>";
echo "<br>";
if ($_FILES["file"]["error"] > 0)
  {
  echo "Error: " . $_FILES["file"]["error"] . "<br>";
  }
else
  {
  echo "Upload: " . $_FILES["file"]["name"] . "<br>";
  echo "Type: " . $_FILES["file"]["type"] . "<br>";
  echo "Size: " . ($_FILES["file"]["size"] / 1024) . " kB<br>";
  echo "Stored in: " . $_FILES["file"]["tmp_name"];
  }
?>
<html>
<body>

<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post"
enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file"><br>
<input type="submit" name="submit" value="Submit">
</form>

</body>
</html>

当我尝试上传大于13MB的文件时,我曾经遇到此错误：

Server Error

500 – Internal server error. There is a problem with the resource you
are looking for,and it cannot be displayed.

然后我添加了error_reporting,我得到了这个：

Network Error (tcp_error)

A communication error occurred: “Can’t send more” The Web Server may
be down,too busy,or experiencing other problems preventing it from
responding to requests. You may wish to try again at a later time.

For assistance,contact your network support team.

这是设置：

upload_max_filesize: 20M

post_max_size: 128M

memory_limit: -1

max_file_uploads: 20

max_execution_time: 50000

max_input_time: 50000

file_uploads: on

default_socket_timeout: 6000

这是web.config文件：

我远程访问了服务器并测试了它的响应是：

PHP Warning: POST Content-Length of 9202605 bytes exceeds the limit
of 8388608 bytes in Unknown on line 0

我该如何解决这个问题？

解决方法

虽然我从cPanel更改了PHP设置,但每当我使用ini_get()时,它都给了我在cPanel中的设置,但它没有用.

我解决了它(如果你可以访问php.ini文件),通过改变php.ini文件本身而不是cPanel的设置.
