PHP exec更改编码 [英] PHP exec change encoding

问题描述

我需要使用php exec命令来解决UTF-8文件名。问题是php exec 命令似乎不了解utf-8。我使用这样的东西：

I need to address UTF-8 filenames with the php exec command. The problem is that the php exec command does not seem to understand utf-8. I use something like this:

echo exec('locale charmap');

返回 ANSI_X3.4-1968

查看这个 SO问题，解决方案如下所示：

looking at this SO question, the solution lookes like that:

echo exec('LANG=de_DE.utf8; locale charmap'); 

但我仍然得到相同的输出： ANSI_X3.4-1968

But I still get the same output: ANSI_X3.4-1968

另一方面 - 如果我在bash命令行上执行此php命令：

On the other hand - if I execute this php command on the bash command line:

php -r "echo exec('LANG=de_DE.UTF8 locale charmap');"

输出为UTF-8。
所以问题是：

The output is UTF-8. So the questions are:

1. 为什么在bash和apache_module / web页面执行php命令有不同的结果？


2. 如果将 exec 设置为UTF-8，如果它作为apache模块运行在网站内？

1. Why is there an different result be executing the php command at bash and at apache_module/web page?
2. How to set UTF-8 for exec if it runs inside a website as apache module?

推荐答案

为了回答我自己的问题 - 我发现了以下解决方案：

To answer my own question - i found the following solution:

使用PHP设置区域环境变量

setting the locale environment variable with PHP

$locale='de_DE.UTF-8';
setlocale(LC_ALL,$locale);
putenv('LC_ALL='.$locale);
echo exec('locale charmap');

这将设置为/返回 UTF-8 。所以我可以通过特殊字符和变音符到linux shell命令。

This sets to / returns UTF-8. So i'm able to pass special characters and umlauts to linux shell commands.
