This repository contains the Docker image used to run PHP CLI containers.

We override the default vhost and map a volume to /var/www/html. In there we expect a directory called public.

The apache container is usually used within a docker-compose.yml file like this:

version: '3.0'

services:
  webserver:
    image: chesszebra/php:7.1-apache
    volumes:
      - ./:/var/www/html

Note that the id of user www-data has been changed to the owner of directory /var/www/html. The same applies to the group www-data. The reason we do this is because this way we can safely create files that are owned by the user that is starting the container. Since we map a volume to /var/www/html, it will always be the correct id.

If you want to change the root directory of your vhost, specify an environment variable VHOST_DIRECTORY. In this example the root of the project is also considered the root of the vhost:

version: '3.0'

services:
  webserver:
    image: chesszebra/php:7.1-apache
    environment:
      VHOST_DIRECTORY: /var/www/html
    volumes:
      - ./:/var/www/html

To use the Apache images without docker-compose, you could do this:

docker run --rm -it -v $(pwd):/var/www/html chesszebra/php:7.1-apache

The php command is already specified in the image. Therefor you can specify flags that php would expect directly after starting the container. Make sure you enable the interactive flags and map a volume to /data.

docker run --rm -it -v $(pwd):/data chesszebra/php:7.3-cli -f file.php

The images come fully equipped with extensions to make our development easier. In certain situations you want to disable extensions. This can be done via the php executable but it's not a fun ride. PHP defines the -n flag which can be used to ignore all extensions. The -d flag can be used to enable a specific extension so to disable a specific extension, you have to disable all extensions and than enable the others explicitly.

For example, the following command will not give any output:

docker run \
    --rm \
    -it \
    chesszebra/php:7.1-cli \
    -n \
    -r 'phpinfo();' \
    | grep swoole 

While the following will:

docker run \
    --rm \
    -it \
    chesszebra/php:7.1-cli \
    -n \
    -d extension=swoole.so \
    -r 'phpinfo();' \
    | grep swoole
