virtPHP: One Box, Multiple Elephpants (Day Camp for Developers: Virtualizing Development 2014)

Get to the know the ins and outs of virtPHP. virtPHP is a shell tool that allows you to create multiple virtual environments for PHP applications on one system, each with unique PHP configurations, global Composer packages, PEAR packages, and PECL extensions, along with the ability to connect environments to other PHP builds located on your system. Think Python’s virtualenv for PHP.

In this talk, co-creator Ben Ramsey will introduce virtPHP and explain how it can benefit any PHP developer’s workflow. We’ll also dive into the internals of virtPHP to see how it creates self-contained virtual environments. Finally, we’ll discuss the project roadmap and how you can help.

29. How does virtPHP work?
30. First, we create the project folder ../{your env}/
31. ../{your env}/ .virtphp bin/ etc/ lib/ share/ Then, we create root folders
32. ../{your env}/ .virtphp bin/ activate composer composer.phar pear peardev pecl php php-config phpize etc/ pear.conf php.ini … Finally, we install a lot of files … lib/ php/ share/ pear/ cache/ cfg/ download/ temp/ tests/ www/ php/
33. ../{your env}/ .virtphp bin/ activate composer composer.phar pear peardev pecl php php-config phpize etc/ pear.conf php.ini … bin/ is your applications … lib/ php/ share/ pear/ cache/ cfg/ download/ temp/ tests/ www/ php/
34. ../{your env}/ .virtphp bin/ activate composer composer.phar pear peardev pecl php php-config phpize etc/ pear.conf php.ini … etc/ is your configurations … lib/ php/ share/ pear/ cache/ cfg/ download/ temp/ tests/ www/ php/
35. ../{your env}/ .virtphp bin/ activate composer composer.phar pear peardev pecl php php-config phpize etc/ pear.conf php.ini … lib/ is where pecl extensions go … lib/ php/ share/ pear/ cache/ cfg/ download/ temp/ tests/ www/ php/
36. ../{your env}/ .virtphp bin/ activate composer composer.phar pear peardev pecl php php-config phpize etc/ pear.conf php.ini … share/pear is for pear support … lib/ php/ share/ pear/ cache/ cfg/ download/ temp/ tests/ www/ php/
37. ../{your env}/ .virtphp bin/ activate composer composer.phar pear peardev pecl php php-config phpize etc/ pear.conf php.ini … share/php is for pear packages … lib/ php/ share/ pear/ cache/ cfg/ download/ temp/ tests/ www/ php/
38. ../{your env}/ .virtphp bin/ activate composer composer.phar pear peardev pecl php php-config phpize etc/ pear.conf php.ini … Enlightened Pair … lib/ php/ share/ pear/ cache/ cfg/ download/ temp/ tests/ www/ php/ virtphp.phar
39. The Keymaster
40. ../{your env}/ .virtphp bin/ activate composer composer.phar pear peardev pecl php php-config phpize etc/ pear.conf php.ini … The Keymaster … lib/ php/ share/ pear/ cache/ cfg/ download/ temp/ tests/ www/ php/ virtphp.phar
41. ../{your env}/ .virtphp bin/ activate composer composer.phar pear peardev pecl php php-config phpize etc/ pear.conf php.ini … The Gatekeeper … lib/ php/ share/ pear/ cache/ cfg/ download/ temp/ tests/ www/ php/
42. The Gatekeeper
43. activate script
44. activate script 1. Check if a virtualenv is running
45. activate script 2. Check if a virtPHP is running
46. activate script 3. Deactivate any virtPHP that might be running
47. activate script 4. Set shell session variables
48. activate script 4. Set shell session variables • PATH • PS1 (prompt) • PHP_INI_SCAN_DIR • VIRTPHP_ENV_PATH • VIRTPHP_COMPOSER_GLOBAL • VIRT_PHP_OLD_VIRTUAL_PATH
49. activate script 4. Set shell session variables Only for the duration of the current terminal session.
50. Let’s see it in action.
