Docker PHP images
---
Docker images built on top of the [official PHP images](https://hub.docker.com/r/_/php/) with the addition of some common and useful extensions, installed with [mlocati/docker-php-extension-installer](https://github.com/mlocati/docker-php-extension-installer), and are meant for *debugging purposes*. You can find these images on the [Docker Hub](https://hub.docker.com/r/chialab/php-dev/) (and if you're reading this file, you're probably already there).
An automated build is set up, so they should be always up-to-date with the Dockerfiles in the [GitHub repository](https://github.com/chialab/docker-php). Also, every time an official PHP image is updated, a rebuild is triggered, so that you will always find the latest security patches installed in these images.
For more production-like environments, you might want to choose an [image *without* XDebug installed](https://hub.docker.com/r/chialab/php/), instead.

As you might have guessed, all tags are built on top of the corresponding tag of the official image. Not all tags are supported in order to easen maintenance.
## Installed extensions
The following modules and extensions have been enabled,
in addition to those you can already find in the [official PHP image](https://hub.docker.com/r/_/php/):
- `amqp`
- `bcmath`
- `bz2`
- `calendar`
- `event`
- `exif`
- `gd`
- `gettext`
- `iconv`
- `imagick`
- `intl`
- `ldap`
- `mbstring`
- `mcrypt` (_only PHP ≤ 7.1_)
- `memcached`
- `mysql` (_only PHP 5.x_)
- `mysqli`
- `pdo_mysql`
- `pdo_pgsql`
- `pgsql`
- `redis`
- `soap`
- `sockets`
- `xdebug`
- `xsl`
- `Zend OPcache`
- `zip`
You will probably not need all this stuff. Even if having some extra extensions loaded ain't a big issue in most cases (especially in a development environment), you will very likely want to checkout this repository, remove unwanted extensions from the `Dockerfile`, and build your own image — for sometimes removing is easier than adding. 😉
## Composer
[Composer](https://getcomposer.org) is installed globally in all images. Please, refer to their documentation for usage hints.
Since 2020/11/01 both version 1 and 2 are installed, available through `composer1` and `composer2` commands respectively (`composer` in now a symlink to `composer2`).
[Prestissimo (composer plugin)](https://github.com/hirak/prestissimo) is installed globally in all images, for use with Composer version 1. It's a plugin that downloads packages in parallel to speed up the installation process of Composer packages.
## Configuring XDebug
XDebug is installed, but not yet configured.
For features like remote debugging, you will need to pass additional configurations via Apache or Nginx configuration files.
### Using Apache
In the directories you want to enable debug in, you will want to specify additional options via `php_value`, e.g.:
```
php_value xdebug.remote_enable 1
php_value xdebug.remote_host 192.168.99.1
```
### Using Nginx
To enable debugging, additional parameters must be passed to the FastCGI PHP interpreter via `fastcgi_param`, e.g.:
```
fastcgi_param PHP_VALUE "xdebug.remote_enable=1\nxdebug.remote_host=192.168.99.1";
```
## Contributing
If you find an issue, or have a special wish not yet fulfilled, please [open an issue on GitHub](https://github.com/chialab/docker-php/issues) providing as many details as you can (the more you are specific about your problem, the easier it is for us to fix it).
Pull requests are welcome, too! 😁 Please, run `make build` and `make test` before attempting a pull request. Also, it would be nice if you could stick to the [best practices for writing Dockerfiles](https://docs.docker.com/articles/dockerfile_best-practices/).
