 1 | # PHP 7 in Docker
 2 | 
 3 | ## Docker container with PHP 7 (nightly)
 4 | 
 5 | ## Features / Aims
 6 | 
 7 | * Allow people to run unit tests with PHP with a 1 line setup & without much to download
 8 | * Get people trying out PHP 7's new features
 9 | 
10 | ## Usage
11 | 
12 | Note: you don't need to do anything with this repo, docker will pull the image for you the 1st time you use it.
13 | 
14 | If you don't have docker, run `sudo apt-get install docker` or similar on your machine.
15 | 
16 | Run a PHP file
17 | 
18 |     docker run -it --rm --name my-php7 -v "$(pwd)":/tmp -w /tmp dave1010/php-nightly "php ./path/to/file.php"
19 | 
20 | You can run executable PHP files (chmod a+x) directly, eg running PHPUnit
21 | 
22 |     docker run -it --rm --name my-php7 -v "$(pwd)":/tmp -w /tmp dave1010/php-nightly ./vendor/bin/phpunit
23 | 
24 | This is quite a long command, so you can alias it:
25 | 
26 |     alias php7='docker run -it --rm --name my-php7 -v "$(pwd)":/tmp -w /tmp dave1010/php-nightly'
27 |     php7 ./vendor/bin/phpunit
28 |     
29 | Check out the examples in this repo for some more PHP 7 goodness.
30 | 
31 | ## Building
32 | 
33 | This is optional -- only needed if you want to change stuff -- as I've packaged it on [Docker hub](https://registry.hub.docker.com/u/dave1010/php-nightly/).
34 | 
35 | Something like this:
36 | 
37 |     docker build -t php-nightly .
38 |     docker ps -a
39 |     docker commit <hash> php:nightly
40 | 
41 | ## TODO
42 | 
43 | Pull requests welcome!
44 | 
45 | * Make so you don't need "php file.php --args" in quotes
46 | * Clean up images, so they're just a few MB, rather than 100s.
47 | * PHP extensions
48 | * Add details to the package on [Docker hub](https://registry.hub.docker.com/u/dave1010/php-nightly/)
49 | * Make it easy / automated to update to the latest nightly / check out different branches of php-src
50 | * More PHP 7 examples
