使用 SetEnv 设置的环境变量未传递给 PHP

Question

我正在设置一些环境变量以从 PHP $_SERVER 全局变量中获取，但它不起作用。变量不在 $_SERVER 中，也不在 phpinfo() 输出中。我已启用所有需要的模块，并尽我所能尝试了所有方法。我遗漏了什么？

这是我的虚拟主机：

<VirtualHost *:80>
ServerName     xpad.seinet.com.local    
ServerAlias    www.xpad.seinet.com.local  *.seinet.com.local www.*.seinet.com.local 

SetEnv SYMFONY__DATABASE__NAME__CLIENTE cliente
SetEnv SYMFONY__DATABASE__USER__CLIENTE cliente
SetEnv SYMFONY__DATABASE__PASSWORD__CLIENTE cliente

DocumentRoot   "/var/www/xpad-single/web"
    DirectoryIndex app.php

<Directory "/var/www/xpad-single/web">

    Allow from All              
</Directory>

Alias /editions_files /publicationProcess3/INPUT_FILES/
<Directory "/publicationProcess3/INPUT_FILES/">
    AllowOverride All
    Require all granted
    Allow from All
</Directory>
