Coding Guidelines

PHP

• PSR-1
• PSR-2
• Entities must implement the Fluent Interface
• Use Yoda conditions
• Do not use is_null($vars) but test the actual value null === $vars
• Do not use ! for the NOT expression in conditional expressions but use false instead:

// Wrong
if (!$expr) {
    ...
}

// Good
if (false === $expr) {
    ...
}
