如何获得系统环境变量到PHP中，同时运行CLI和放大器; Apache2Handler？ [英] How to get system environment variables into PHP while running CLI & Apache2Handler?

问题描述

我的系统是的的Ubuntu 。我将我的环境变量的/ etc /环境。

My system is Ubuntu and I have set my environment variables in /etc/environment.

如果我使用的 CLI 运行 PHP 脚本 - 从环境变量在/ etc /环境的认可。

If I'm running PHP script using CLI - environment variables from /etc/environment are recognized.

但是，如果我去执行 PHP 脚本直通 HTTP：//domain/test.php （即 apache2handler ）完全相同的脚本打印出空，从的/ etc /环境不加载。

But, if I go to execute PHP script thru http://domain/test.php (that is apache2handler) exactly the same script prints out NULL, meaning environment variables from /etc/environment are not loaded.

我做的/ etc / apache2的/ envvars中并解决了这个问题。

The fix I did was adding variables in /etc/apache2/envvars and that solved the problem.

但是，这是两个不同的文件，然后必须保持同步。

But that is two different files, which then have to be kept in sync.

我怎样才能让 PHP / 的Apache 从载荷和认识环境变量在/ etc /环境（系统） ？

How can I make PHP / Apache load and recognize environment variables from /etc/environment (system)?

编辑：为了澄清的事情，当我说'没有加载到PHP这意味着从变量的/ etc /环境未在 $设置_ SERVER ， $ _ ENV ，的getenv（）和做不存在 $ GLOBALS 。换句话说不会被加载到PHP。

To clarify things, when I say 'not loaded into PHP' it means variables from /etc/environment are not set in $_SERVER, $_ENV, getenv() and do not exists in $GLOBALS. In other words 'are not loaded into PHP'.

推荐答案

我有完全相同的问题。为了解决这个问题，我只是来源的的/ etc /环境中的的/ etc / apache2的/ envvars中的

I had exactly the same problem. To solve it, I just sourced /etc/environment inside /etc/apache2/envvars.

的的/ etc /环境中的含量的：

export MY_PROJECT_PATH=/var/www/my-project
export MY_PROJECT_ENV=production
export MY_PROJECT_MAIL=[e-mail]

的内容的的/ etc / apache2的/ envvars中的：

# Load all the system environment variables.
. /etc/environment

现在，我可以在Apache虚拟主机配置文件，并在PHP中使用这些变量。

Now, I'm able to use these variables in the Apache Virtual Host config files and in PHP.

下面是一个Apache虚拟主机的例子：

Here's an example of an Apache virtual host:

<VirtualHost *:80>
  ServerName my-project.com
  ServerAlias www.my-project.com
  ServerAdmin ${MY_PROJECT_MAIL}
  UseCanonicalName On

  DocumentRoot ${MY_PROJECT_PATH}/www

  # Error log.
  ErrorLog ${APACHE_LOG_DIR}/my-project.com_error.log
  LogLevel warn

  # Access log.
  <IfModule log_config_module>
    LogFormat "%h %l %u %t \"%m %>U%q\" %>s %b %D" clean_url_log_format
    CustomLog ${APACHE_LOG_DIR}/my-project.com_access.log clean_url_log_format
  </IfModule>

  # DocumentRoot directory
  <Directory ${MY_PROJECT_PATH}/www>
    # Disable .htaccess rules completely, for better performance.
    AllowOverride None
    Options FollowSymLinks Includes
    Order deny,allow
    Allow from All

    Include ${MY_PROJECT_PATH}/config/apache/inc.mime-types.conf
    Include ${MY_PROJECT_PATH}/config/apache/inc.cache-control.conf

    # Rewrite rules.
    <IfModule mod_rewrite.c>
      RewriteEngine on
      RewriteBase /

      # Include all the common rewrite rules (for http and https).
      Include ${MY_PROJECT_PATH}/config/apache/inc.rewriterules-shared.conf
    </IfModule>
  </Directory>
</VirtualHost>

这将是如何使用PHP访问它们的例子：

And this would be an example of how to access them with PHP:

<?php
header('Content-Type: text/plain; charset=utf-8');
print getenv('MY_PROJECT_PATH') . "\n" .
      getenv('MY_PROJECT_ENV') . "\n" .
      getenv('MY_PROJECT_MAIL') . "\n";
?>
