PHP在帖子后阅读上传的文件(PHP reading uploaded file after post)

PHP阅读上传的文件内容问题

我上传了一个txt文件，我做了以下操作

print_r($_FILES);

输出是

Array ( [up_file] => Array ( [name] => upload.txt [type] => text/plain [tmp_name] => /tmp/phpbyrYwN [error] => 0 [size] => 26 ) )

当我做了以下

$tmp_file_path = strtolower($_FILES['up_file']['tmp_name']); //rename file $file_content = file_get_contents($tmp_file_path);

$ tmp_file_path返回me / tmp / phpbyrYwN但$ file_content什么都没有返回，我通过ssh转到root并检查/ tmp但是没有看到名字/ tmp / phpbyrYwN的任何文件，我该怎么做才能解决这个问题。

我应该在代码的任何部分中声明上传文件的默认目录吗？

PHP reading uploaded file content issue

I upload a txt file, and I did the following

print_r($_FILES);

The output was

Array ( [up_file] => Array ( [name] => upload.txt [type] => text/plain [tmp_name] => /tmp/phpbyrYwN [error] => 0 [size] => 26 ) )

When I did the following

$tmp_file_path = strtolower($_FILES['up_file']['tmp_name']); //rename file $file_content = file_get_contents($tmp_file_path);

The $tmp_file_path return me /tmp/phpbyrYwN but $file_content return nothing, I went to root via ssh and check /tmp but did not see any file by the name /tmp/phpbyrYwN , what should I do to resolve this.

Should I state a default directory for uploaded file in any part of the code or ?

最满意答案

您的文件系统似乎区分大小写，

并尝试读取较低的文件名。

尝试没有strtolower ：

<?php $tmp_file_path = $_FILES['up_file']['tmp_name']; $file_content = file_get_contents($tmp_file_path);

your file system seem to be case-sensitive,

and you try to read the lower-cased file name.

try it without the strtolower:

<?php $tmp_file_path = $_FILES['up_file']['tmp_name']; $file_content = file_get_contents($tmp_file_path);
