- find your
php.ini - make sure the directive
extension_dir=C:\path\to\server\php\extis set and adjust the path (set your PHP extension dir) - make sure the directive
extension=php_mbstring.dllis set (uncommented)
- 找你的
php.ini - 确保
extension_dir=C:\path\to\server\php\ext设置了指令并调整路径（设置您的 PHP 扩展目录） - 确保
extension=php_mbstring.dll设置了指令（未注释）
If this doesn't work and the php_mbstring.dll file is missing, then the PHP installation of this stack is simply broken.
如果这不起作用并且缺少 php_mbstring.dll 文件，那么这个堆栈的 PHP 安装就被破坏了。
