php - 调用 shell 命令的脚本在 CLI 中工作，而不是在 Web 上下文中工作

Question

我有一个非常简单的脚本，可以在 CLI 环境中运行，但不能在 FPM 环境中运行，尽管两个配置文件完全相同。

它是这样的:

<?php
echo shell_exec('mediainfo -f --Output=XML --Language=raw /home/mstrasser/Vidéos/Motocross.mp4 2>&1');?>

请注意“Vidéos”中的重音，并请注意它与没有重音的路径完美配合。

这是 CLI 上下文中的输出:

这是网络上下文中的输出:

我尝试更改LC_ALL，更改页面字符集，但没有成功。可能是什么问题？

退出状态代码为1。

Answer 1

我看起来像是字符集问题。 你说你已经用这种方式尝试过 LC_ALL 了吗？

$locale = 'fr_FR.utf-8';
setlocale(LC_ALL, $locale);
putenv('LC_ALL='.$locale);
