I use the repository's Dockerfile to build the image, but I can't build it successfully：

I temporarily commented out iconv and compiled it. It depends on what is the best way for you

[xdendev]

cant, becouse i use some functions from this lib

[duiniwukenaihe]

I took a closer look:

https://github.com/docker-library/php/blob/master/7.4/alpine3.15/fpm/Dockerfile 

already Use gnu-libiconv for php iconv extension on alpine In fact, iconv can be commented out here. After playing a mirror, I also found that there is iconv。

[duiniwukenaihe]

and 8.0 is also. so you can commented out here

[xdendev]

if i comment iconv i still can use functions iconv() in php ? php 8.1

[duiniwukenaihe]

I took the image of php 7.48-fpm and commented out the iconv image and started it. Entering the container to execute php-m is dependent on iconv. you may try it 。richarvey/nginx-php-fpm image three is based on the official base image:

https://github.com/docker-library/php/blob/master/8.1/alpine3.15/fpm/Dockerfile. 
```I took a look and there is gun-libiconv

[richarvey]

I can confirm that this can be removed and still you can use the lib inconv commands. It's now fixed in the 2.0.5 release
