PHPmyadmin问题 - 致命错误：未捕获错误：调用未定义函数mb_detect_encoding（）

Posted 2021-05-03

当我尝试从我的localhost运行phpmyadmin时，我一直遇到这个问题。

Fatal error: Uncaught Error: Call to undefined function mb_detect_encoding() 
in C:Apache24htdocsphpmyadminlibrariesphp-gettextgettext.inc:177 Stack

我已经多次通过并尝试了所有关于这个问题我能找到的建议并且尚未弄明白。我没有运气，尝试了各种“/”“”建议。

这是我的httpd.conf设置：

ServerRoot "c:/Apache24"


 </IfModule>
 LoadModule php7_module "c:/php/php7apache2_4.dll"
 AddHandler application/x-httpd-php .php
 PHPIniDir "c:PHP"

这是我的php.ini设置：

 ; Directory in which the loadable extensions (modules) reside.
 ; http://php.net/extension-dir
   extension_dir = "C:/PHP/ext"
 ; On windows:
   extension_dir = "C:/PHP/ext"

软件/硬件

 - Windows Server 2016R2
 - PHP 7.0.13
 - Phpmyadmin (C:Apache24htdocsphpmyadmin)
 - Apache 2.4
 - MySQL 5.7.1

我感谢你能给我的任何帮助。不知道采取什么措施。

答案

我在使用Bitnami WAMP Stack版本7.0.12-0的Windows 10上遇到了同样的问题（不确定你是使用Bitnami还是其他一些WAMP堆栈，或者没有）。我放弃了故障排除（你试过运行命令：

cd php
deplister extphp_mbstring.dll

在命令提示符中，检查PHP_MBSTRING.DLL的依赖关系，看看是否有任何“NOTFOUND”错误？），并且刚刚安装了最新版本的Bitnami，7.0.13-1，然后phpMyAdmin立即工作。 （我在之前版本的Bitnami中稍微更改了我的httpd.conf和php.ini，所以我可能已经破坏了phpMyAdmin这些更改）。

另一答案

我有同样的问题，我只是在php.ini文件中更新完整的扩展文件夹路径

extension_dir = "C:/wamp/bin/php/php7.1.13/ext/"

并更新了最新的phpmyadmin版本，因为phpmyadmin4.1.14与php7不兼容。我希望它能解决你的问题
