Development Practices

@asgrim

Code Defensively

@asgrim

SOLID

@asgrim

Composition over Inheritance

@asgrim

Composition over Inheritance

final class Thing implements ThingInterface{ public function foo() { // (does something) }}final class CachingThing implements ThingInterface{ public function __construct(ThingInterface $real, CacheInterface $cache) { $this->real = $real; $this->cache = $cache; } public function foo() { if (!$this->cache->has('foo')) { $this->cache->put('foo', $this->real->foo()); } return $this->cache->get('foo'); }}

@asgrim

Testing

@asgrim

Naming things

@asgrim

Separation of concerns

@asgrim

Use PHP 7 (when it’s out)

@asgrim

Automate all the things!

Summary

● Set up a familiar working environment● Git + GitHub● Use Zend Server for PHP● Composer for dependencies● GitHub Flow + rebasing branching strategy● Use good development practices● Automate testing, coverage, coding standards, etc.● Set up Continuous Integration builds● Code Review every change (PR)● Local development makes things easier● Use a good DBAL● One-click-deployments are mandatory

Any questions?
