phpMyAdmin Fatal error: Call to undefined function __()
提问by Jim
Server running RHEL 7 and PHP 5.4.16. When I try to open /phpMyAdmin in my browser, I'm given the error:
运行 RHEL 7 和 PHP 5.4.16 的服务器。当我尝试在浏览器中打开 /phpMyAdmin 时，出现错误：

I believe I've installed all required libraries and that apache has the proper permissions for the session.save_path directory, which were the issues previous times that this question had been asked. See: Call to undefined function __() error - phpMyAdmin
我相信我已经安装了所有必需的库，并且 apache 对 session.save_path 目录具有适当的权限，这是之前提出这个问题的问题。请参阅：调用未定义的函数 __() 错误 - phpMyAdmin
Can someone give me a hint based on that call stack? Here are the functions from the lines that the stack trace references, with the relevant line written in the left margin:

The problem was the wrong permissions for the /etc/phpMyAdmindirectory. The web server user, apache, had proper permissions for the session.save_pathdirectory, but apache couldn't read from my config.inc.php file. Changing the owner of /etc/phpMyAdmin to the apache user and changing the permissions to 755 solved the problem.
问题是/etc/phpMyAdmin目录的权限错误。Web 服务器用户 apache 对该session.save_path目录具有适当的权限，但 apache 无法从我的 config.inc.php 文件中读取。将 /etc/phpMyAdmin 的所有者更改为 apache 用户并将权限更改为 755 解决了问题。
Looking at the checkConfigSource()function in Config.class.phpled me to believe that if the problem was with accessing the configuration file then I would have received the error 'Existing configuration file (%s) is not readable.'instead of Call to undefined function __()Does anyone know why that wasn't the case?
查看中的checkConfigSource()函数Config.class.php让我相信，如果问题出在访问配置文件上，那么我会收到错误'Existing configuration file (%s) is not readable.'而Call to undefined function __()不是有谁知道为什么不是这样？
This was a pretty basic problem/solution, but unless someone suggests otherwise I think I'll leave it up since this exact problem/solution isn't addressed in other discussions of the Fatal error: Call to undefined function __() in /usr/share/phpMyAdmin/libraries/core.lib.phperror when trying to start phpMyAdmin after installation.
这是一个非常基本的问题/解决方案，但除非有人另有建议，否则我认为我会保留它，因为Fatal error: Call to undefined function __() in /usr/share/phpMyAdmin/libraries/core.lib.php在安装后尝试启动 phpMyAdmin 时，在其他关于错误的讨论中没有解决这个确切的问题/解决方案。

Had the same Error message from phpMyAdmin :: FastCGI sent in stderr: "PHP message: PHP Fatal error: Call to undefined function __() in /usr/share/phpMyAdmin/libraries/core.lib.php on line 245" while reading response header from upstream, client:

Solution that worked on my Fedora 22 server x86_64 using nginx :
changing the owner and the group identifier from root:apache on the file /var/lib/php/session
to root:nginx
using the command sudo chown -Rfv root:nginx /var/lib/php/session.
使用 nginx 在我的 Fedora 22 服务器 x86_64 上运行的解决方案

使用命令 将文件 /var/lib/php/session 上的所有者和组标识符从 root:apache 更改为 root:nginx sudo chown -Rfv root:nginx /var/lib/php/session。

If phpmyadmin was working fine and then suddenly stops working for no reason with a bizarre and useless error message, you might try deleting your php sessions.
如果 phpmyadmin 工作正常，然后突然无故停止工作并出现奇怪且无用的错误消息，您可以尝试删除您的 php 会话。
rm -rf /var/lib/php/sessions/*
The exact location may very depending on OS and version, and this will delete all active sessions, not just yours, but it can fix some "suddenly stopped working" issues when you haven't changed anything and it was working fine before.
确切位置可能非常取决于操作系统和版本，这将删除所有活动会话，而不仅仅是您的，但它可以解决一些“突然停止工作”的问题，当您没有更改任何内容并且之前工作正常时。

For me it was different issue. I had given 777 permissions to phpMyAdmin forlder. When I changed it to 755, it worked fine.
对我来说，这是不同的问题。我已向 phpMyAdmin 文件夹授予 777 权限。当我将其更改为 755 时，它运行良好。
Hope this will help someone.
