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:
fatal error :调用/usr/share/phpMyAdmin/libraries/core.lib.php 中的未定义函数 __() 第 242 行

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，这是以前问过这个问题的问题。请参阅:Call to undefined function __() error - phpMyAdmin
有人可以根据那个调用堆栈给我提示吗？ 以下是堆栈跟踪引用的行中的函数，相关行写在左边距中:
core.lib.php 第 242 行:

最佳答案
问题是 /etc/phpMyAdmin 的权限错误目录。 Web 服务器用户 apache 对 session.save_path 具有适当的权限目录，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。
查看 checkConfigSource()在 Config.class.php 中发挥作用让我相信，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.'而不是 Call to undefined function __()有谁知道为什么不是这样？
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，因为在 Fatal error: Call to undefined function __() in /usr/share/phpMyAdmin/libraries/core.lib.php 的其他讨论中没有解决这个确切的问题/解决方案。安装后尝试启动 phpMyAdmin 时出错。
关于phpMyAdmin fatal error : Call to undefined function __()，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/27537617/
