How i can install snmp-module in php on Dokerfile

My problem: When i run command

docker build –no-cache -t php –progress=plain .

My container is building, but I get Error in my PHP-project:

Error Call to undefined function snmp2_real_walk()

Command install in Dockerfile is’t work… I need help!!

My Dockerfile:

FROM php:7.4-apache

# Use the default production configuration
RUN mv "$PHP_INI_DIR/php.ini-production" "$PHP_INI_DIR/php.ini"

RUN if command -v a2enmod >/dev/null 2>&1; then 
a2enmod rewrite headers 
;fi

RUN apt-get update

WORKDIR /app

I’ve tried a lot of options. Editing the

php.ini-production

file did not lead to the expected result. At the same time, the php.ini file also does not exist, but the command is present…
