我在php.ini里面看了确实没有iconv这个扩展插件
没有办法，只好进行apt安装
安装的时候却提示
moodle@moodle:/$ sudo apt-get install php7.2-iconv
Reading package lists... Done

Note, selecting 'php7.2-common' instead of 'php7.2-iconv'
php7.2-common is already the newest version (7.2.15-0ubuntu0.18.10.1).

请问我该如何安装iconv这个扩展插件并启用他

感谢各位大神：）

不懂php，但iconv已经包含在php7.2-common里了。
插件文件在/usr/lib/php/20170718/iconv.so
配置在/usr/share/php7.2-common/common/iconv.ini

恩谢谢楼主的回答，但我不知道为嘛还老提示我要启动这个控件。。。
我即使在php.ini中加了
extension=iconv
或者
extension=php_iconv
这个重新启动apache2服务后还是如此
