How do I containerize PHP applications with Docker?

Containerizing PHP applications with Docker involves creating a Dockerfile to define the environment needed for your application, including specifying PHP, web servers, and other dependencies. This approach helps in ensuring consistent application deployment across different systems.

Example Dockerfile for PHP Application


        FROM php:7.4-apache

        # Install necessary PHP extensions
        RUN docker-php-ext-install mysqli && \
            docker-php-ext-enable mysqli

        # Copy application source code
        COPY src/ /var/www/html/

        # Expose the port the app runs on
        EXPOSE 80

        # Set the working directory
        WORKDIR /var/www/html
