How to Check PHP Version in Docker Container?

To check the PHP version in a Docker container, you can follow these steps:

  1. Make sure that you have the Docker command-line interface (CLI) installed on your host machine. You can check if Docker is installed by running the following command:Copy codedocker --version
  2. If you do not have Docker installed, you can install it by following the instructions at the following link:
  3. To check the PHP version in a Docker container, you will need to run a command inside the container. You can use the exec command to run a command in a running container.

4.  First, list the running containers using the following command:Copy codedocker ps

This will list the running containers and their names or IDs.

5. Run the following command to execute the php -v command inside the container:

docker exec <container-name-or-id> php -v

Replace <container-name-or-id> with the name or ID of the container you want to check the PHP version in.

This will execute the php -v command inside the container, which will display the PHP version.

For example, if the container name is my-php-app, you can run the following command to check the PHP version:Copy codedocker exec my-php-app php -v

By following these steps, you should be able to check the PHP version in a Docker container.

Is php works on docker container?

Yes, PHP can be run inside a Docker container. Docker is a platform that allows you to package applications and their dependencies in containers, which are lightweight, standalone, and portable environments that can be easily run on any host with Docker installed.

To run PHP inside a Docker container, you will need to create a Docker image that contains a PHP installation. You can do this by creating a Dockerfile, which is a text file that contains instructions for building a Docker image.

Here is an example Dockerfile that installs PHP in an Ubuntu-based container:

FROM ubuntu:latest RUN apt-get update && apt-get install -y \ php \ php-fpm \ php-mysql \ php-curl \ php-gd \ php-mbstring \ php-xml \ php-zip CMD ["php", "-a"]

To build a Docker image from this Dockerfile, you can run the following command in the same directory as the Dockerfile:Copy codedocker build -t my-php-app .

This will build a Docker image called my-php-app that contains PHP and some common PHP extensions.

To run the image as a container, you can use the docker run command:Copy codedocker run -it my-php-app

This will start a PHP interactive shell inside the container, where you can run PHP commands.

You can also run a PHP script inside the container by mounting a volume and specifying the script file as an argument to the php command:Copy codedocker run -v /path/to/my/script:/app/script.php my-php-app php /app/script.php

This will run the script.php file inside the container, using the PHP installation in the container.

By using Docker, you can easily run PHP in a containerized environment and deploy it to any host with Docker installed.
