Http 文件上传 - 超过 25mb 的文件失败 - PHP 上传脚本

我已经为此苦苦挣扎了 20 多个小时,现在我真的很感谢您的帮助!

我在这里简化了问题,所以代码非常简单。基本上这个上传脚本工作得很好,直到我尝试上传大于 25MB 的文件,然后它失败了。 PHP 没有给出任何错误。

index.htm

<form enctype="multipart/form-data" action="upload.php" method="POST">
Choose a file to upload: <input name="uploadedfile" type="file" /><br />
<input type="submit" value="Upload File" />
</form>

upload.php

<?php
$target_path = "uploaded/";
$target_path = $target_path.basename( $_FILES['uploadedfile']['name']); 
/***/highlight_string(print_r($_FILES, true)); //check array

if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ". basename($_FILES['uploadedfile']['name'])." has been uploaded";
} else {
    echo "There was an error uploading the file, please try again!";
}
?>

php.ini

[PHP]

post_max_size = 32M
upload_max_filesize = 32M

我的主机通知我服务器上的上传限制为 32MB。运行 phpinfo() & ini 中的变量正在更改。这不是超时问题(下载文件时运行了 16MB 上传 - 它比 25MB 上传时间长了几分钟,但仍然有效)。

我已经将 $_Files 数组作为字符串吐出以进行错误检查,这就是失败时得到的结果:

Array
(
    [uploadedfile] => Array
        (
            [name] => 30.tif
            [type] => 
            [tmp_name] => 
            [error] => 7
            [size] => 0
        )

)
There was an error uploading the file, please try again!

有什么想法吗?在不同的服务器上尝试过,都出现同样的问题。

I've been banging my head against this for 20+ hours now I would really appreciate some help!

I have simplified the problem here so the code is very simple. Basically this upload script works perfectly until I try to upload a file bigger than 25MB then it fails. PHP gives no errors.

index.htm

<form enctype="multipart/form-data" action="upload.php" method="POST">
Choose a file to upload: <input name="uploadedfile" type="file" /><br />
<input type="submit" value="Upload File" />
</form>

upload.php

<?php
$target_path = "uploaded/";
$target_path = $target_path.basename( $_FILES['uploadedfile']['name']); 
/***/highlight_string(print_r($_FILES, true)); //check array

if (move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
    echo "The file ". basename($_FILES['uploadedfile']['name'])." has been uploaded";
} else {
    echo "There was an error uploading the file, please try again!";
}
?>

php.ini

[PHP]

post_max_size = 32M
upload_max_filesize = 32M

My host informed me that the upload limit on the server is 32MB. Ran phpinfo() & the variables in the ini are being changed. It is not a timeout issue (ran a 16mb upload when downloading a file - it took several minutes longer than the 25MB upload but still worked).

I have been spittin out the $_Files array as a string for error checking, heres what I get when it fails:

Array
(
    [uploadedfile] => Array
        (
            [name] => 30.tif
            [type] => 
            [tmp_name] => 
            [error] => 7
            [size] => 0
        )

)
There was an error uploading the file, please try again!

Any ideas? Tried it on different servers with the same problem.

根据 this,它无法将文件写入磁盘。你能检查配额/磁盘空间/等吗?

According to this, it failed to write files to disk. Can you check quota/disk space/etc.?

memory_limit 也可能限制可上传文件的大小。

memory_limit might also restrict the size of uploadable files.

您的错误不是大小,错误代码7是因为文件“无法保存在磁盘中”。

要了解更多错误,请阅读:上传代码错误

尝试更改指令“在 php.ini 文件中添加“upload_tmp_dir”并检查是否允许上传文件:“file_uploads = On”。

Your error don't is for the size, the error code 7 is because the file "can't be save in the disk."

to more errors read: Upload code errors

Try change the directive "upload_tmp_dir" in php.ini file and check if is allow the upload of file: 'file_uploads = On'.

谢谢大家,我现在确信这是一个主机问题,而不是我这边的问题 - 尽管我已经在多个主机上尝试过了 - 我认为 http post 被限制在 25MB 左右是很常见的。

我现在已将上传程序设置为最大文件大小为 20MB,这应该使其在大多数主机上都非常安全。

Thanks everybody, I'm sure now that it is a host problem, not a problem on my end - even though I've tried it on several hosts - I think it's pretty common for http post to be limited to around 25MB.

I have now set my uploader to take a maximum file size of 20MB, that should make it pretty safe on most hosts.
