Convention

QuidPHP/Orm is built on the following conventions:

  • Coding: No curly braces are used in a IF statement if the condition can be resolved in only one statement.
  • Config: A special $config static property exists in all classes. This property gets recursively merged with the parents' property on initialization.
  • Dynamic singleton: Table, Col, Row and Cell objects can only exist once for a same source.
  • Traits: Traits filenames start with an underscore (_).
  • Type: Files, function arguments and return types are strict typed.
