如何在运行CLI& Apache2Handler？ [英] How to get system environment variables into PHP while running CLI & Apache2Handler?

问题描述

我的系统是 Ubuntu ，我已将环境变量设置为 / etc / environment 。

如果我使用 CLI 运行 PHP 脚本 - / etc / environment 中的环境变量是

但是，如果我执行 PHP 脚本通过 http：//domain/test.php （即 apache2handler ）完全相同的脚本打印出NULL，意味着 / etc / environment 中的环境变量未加载

我所做的修复是在 / etc / apache2 / envvars 中添加变量，解决了这个问题。 / p>

但这是两个不同的文件，然后必须保持同步。

我如何使 PHP / Apache 加载并识别来自 / etc / environment （系统）的环境变量？

编辑：澄清事情，当我说'没有加载到P HP'表示 / etc / environment 中的变量未在 $ _ SERVER ， $中设置_ code>， getenv（），并且不存在于 $ GLOBALS 中。换句话说没有加载到PHP。

解决方案

我有完全相同的问题。为了解决这个问题，我刚刚在 / etc / apache2 / envvars 中采购了 / etc / environment 。 b
$ b

/ etc / environment 的内容：

 code> export MY_PROJECT_PATH = / var / www / my-project 
 export MY_PROJECT_ENV = production 
 export MY_PROJECT_MAIL=[e-mail] 
  / pre> 
 
 
  / etc / apache2 / envvars 的内容：
 ＃加载所有系统环境变量。 
。 / etc / environment 
  
现在，我可以在Apache Virtual Host配置文件中使用这些变量在PHP中。
 
 
 
以下是Apache虚拟主机的示例：
 < VirtualHost *：80> 
 ServerName my-project.com 
 ServerAlias www.my-project.com 
 ServerAdmin $ {MY_PROJECT_MAIL} 
 UseCanonicalName 
 
 DocumentRoot $ {MY_PROJECT_PATH} / www 
 
＃错误日志。 
 ErrorLog $ {APACHE_LOG_DIR} /my-project.com_error.log 
 LogLevel warn 
 
＃访问日志。 
< IfModule log_config_module> 
 LogFormat％h％l％u％t \％m％> U％q\％> s％b％Dclean_url_log_format 
 CustomLog $ {APACHE_LOG_DIR} / my- project.com_access.log clean_url_log_format 
< / IfModule> 
 
＃DocumentRoot目录
<目录$ {MY_PROJECT_PATH} / www> 
＃完全禁用.htaccess规则，以获得更好的性能。 
 AllowOverride无
选项FollowSymLinks包含
订单拒绝，允许
从全部
 
中包含$ {MY_PROJECT_PATH} /config/apache/inc.mime- types.conf 
包含$ {MY_PROJECT_PATH} /config/apache/inc.cache-control.conf 
 
＃重写规则。 
< IfModule mod_rewrite.c> 
 RewriteEngine on 
 RewriteBase / 
 
＃包含所有常见的重写规则（用于http和https）。 
包含$ {MY_PROJECT_PATH} /config/apache/inc.rewriterules-shared.conf 
< / IfModule> 
< / Directory> 
< / VirtualHost> 
  
这是一个如何使用PHP访问它们的示例：
 <？php 
 header（'Content-Type：text / plain; charset = utf-8'）; 
 print getenv（'MY_PROJECT_PATH'）。 \\\
。 
 getenv（'MY_PROJECT_ENV'）。 \\\
。 
 getenv（'MY_PROJECT_MAIL'）。 \\\
;

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

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

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.

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

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

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

EDIT: 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'.
解决方案
I had exactly the same problem. To solve it, I just sourced /etc/environment inside /etc/apache2/envvars.

The content of /etc/environment:
export MY_PROJECT_PATH=/var/www/my-project
export MY_PROJECT_ENV=production
export MY_PROJECT_MAIL=[e-mail]
The content of /etc/apache2/envvars:
# Load all the system environment variables.
. /etc/environment
Now, I'm able to use these variables in the Apache Virtual Host config files and in PHP.

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>
And this is 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";
?>
