phpMyAdmin致命错误:调用未定义的函数__() [英] phpMyAdmin Fatal error: Call to undefined function __()
问题描述
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，出现错误消息:
Server running RHEL 7 and PHP 5.4.16. When I try to open /phpMyAdmin in my browser, I'm given the error:
Fatal error: Call to undefined function __() in /usr/share/phpMyAdmin/libraries/core.lib.php on line 242

我相信我已经安装了所有必需的库，并且该apache对session.save_path目录具有适当的权限，这是以前询问此问题时遇到的问题.请参阅:调用未定义函数__()的错误-phpMyAdmin
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
有人可以根据该调用堆栈给我一个提示吗? 以下是堆栈跟踪引用的行中的函数，相关行写在左边界:
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:

推荐答案
问题是对/etc/phpMyAdmin目录的权限错误. Web服务器用户apache对session.save_path目录具有适当的权限，但是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可解决此问题.
The problem was the wrong permissions for the /etc/phpMyAdmin directory. The web server user, apache, had proper permissions for the session.save_path directory, 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.
查看Config.class.php中的checkConfigSource()函数使我相信，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.'而不是Call to undefined function __()吗?有人知道为什么吗?这样吗?
Looking at the checkConfigSource() function in Config.class.php led 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?
这是一个非常基本的问题/解决方案，但是除非有人提出其他建议，否则我认为我会把它保留下来，因为在尝试在以后尝试启动phpMyAdmin时在Fatal error: Call to undefined function __() in /usr/share/phpMyAdmin/libraries/core.lib.php错误的其他讨论中都没有解决这个确切的问题/解决方案安装.
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.php error when trying to start phpMyAdmin after installation.
