Test PHP codes using Docker container

PHP installed in your local machine is PHP 7. You want to test if your codes work in PHP 8.3. You can use Docker container to do the testing.

#Dockerfile
FROM php:8.3.11RC2-zts-alpine3.20

RUN apk update
RUN apk add php83-dom php83-tokenizer php83-fileinfo php83-simplexml \
        apache2 php83  php83-apache2 php83-ctype php83-openssl \
        php83-curl php83-pecl-apcu php83-opcache php83-bcmath php83-xml \
        php83-intl php83-iconv php83-mbstring php83-session php83-common \
        bash util-linux-misc
RUN apk upgrade

COPY ./ /var/src

<?
//test.php
echo "Hello world", "\n";

Step one: put Dockerfile into the same directory where test.php (your php codes) is in.

Step two: Build image, run container and do testing.

#build docker image
docker build --no-cache -t my-test .

#run docker image and go inside container
docker run -it my-test bash

# go to working directory and run the script
cd /var/src
php test.php
