当文件太大时上传不起作用 [英] Upload doesn't work right when the file is too big

问题描述

我有一个PHP应用程序，可以上传文件。当我上传大多数文件并执行 print_r（$ _ FILES）时，我得到如下所示：

  Array 
（
 [import] => Array 
（
 [name] => Array 
（
 [ excel_file] => COD MKTG 2.csv 
）
 
 [type] => Array 
（
 [excel_file] => application / vnd.ms -excel 
）
 
 [tmp_name] => Array 
（
 [excel_file] => / tmp / phpy8mEKn 
）
 
 [error] => Array 
（
 [excel_file] => 0 
）
 
 [size] => Array 
（
 [excel_file] => 1584286 
）
 
）
 
）
  

我有另一个CSV文件，我更喜欢13兆字节，当我尝试上传时，我得到这个：
$ b $ pre $ $ $ $ c $ Array
（
[import] =>数组
（
[name] =>数组
（
[excel_file] => COD MKTG.csv
）

[数组
（
[excel_file] =>
）

[tmp_name] =>数组
（
[excel_file] =>
）

[error] => Array
（
[excel_file] => 1
）

[size] => Array
（
[excel_file] => 0
）

）

）

我不会收到任何错误，说文件太大。我只是得到一个格式不正确 $ _ FILES 。我在php.ini中将 post_max_size 设置为100MB。为什么会发生这种情况？

解决方案

根据PHP文档，错误代码1是 UPLOAD_ERR_INI_SIZE ：上传的文件超过了php.ini文件中的upload_max_filesize指令。

您需要确保以下所有变量设置正确：

upload_max_filesize - 上传任何单个文件的最大大小

max_file_uploads - 允许上传的文件总数

post_max_size - 所有数据的总和被张贴（表单数据+文件）

memory_limit - mu st> post_max_size，为PHP +脚本开销留出空间

最重要的是，还有web服务器的限制。 Apache的 LimitRequestBody 在PHP进入图片之前很久就会使用。

I have a PHP app where I can upload files. When I upload most files and do a print_r($_FILES), I get something like this:

Array
(
    [import] => Array
        (
            [name] => Array
                (
                    [excel_file] => COD MKTG 2.csv
                )

            [type] => Array
                (
                    [excel_file] => application/vnd.ms-excel
                )

            [tmp_name] => Array
                (
                    [excel_file] => /tmp/phpy8mEKn
                )

            [error] => Array
                (
                    [excel_file] => 0
                )

            [size] => Array
                (
                    [excel_file] => 1584286
                )

        )

)

I have another CSV file that's more like 13 megabytes, and when I try to upload that, I get this:

Array
(
    [import] => Array
        (
            [name] => Array
                (
                    [excel_file] => COD MKTG.csv
                )

            [type] => Array
                (
                    [excel_file] => 
                )

            [tmp_name] => Array
                (
                    [excel_file] => 
                )

            [error] => Array
                (
                    [excel_file] => 1
                )

            [size] => Array
                (
                    [excel_file] => 0
                )

        )

)

I don't get any error saying the file's too big. I just get a malformed $_FILES. I have post_max_size in php.ini set to 100MB. Why is this happening?

解决方案

As per the PHP docs, error code 1 is UPLOAD_ERR_INI_SIZE: "The uploaded file exceeds the upload_max_filesize directive in php.ini"

You need to make sure all the following variables are properly set:

upload_max_filesize - max size of any individual file in an upload
max_file_uploads - total number of files allowed to be uploaded
post_max_size - sum total of all data being POSTed (form data + files)
memory_limit - must be > post_max_size, to allow space for PHP + script overhead

And on top of that, there's the web server limits as well. Apache's got LimitRequestBody which would apply long before PHP ever enters the picture.
