This component includes class definitions for php basic data types like:

  • Boolean
  • Floating point
  • Integer
  • String
  • Numeric
  • DataArray

By using this component, you are able to use type hints also for basic data types.

The build status of the current master branch is tracked by Travis CI: Build Status


  • Enables type hints for basic php types
  • Types shipped with useful methods
  • Are comparable with native php types by using "=="
  • Provides generic type casting by implemented "toString()" methods (and so on)
  • Provides type migration by from and to methods



 * Class with type hint for string
 * @author stev leibelt <>
 * @since 2013-08-04
class MyClass
     * @var array
     * @author stev leibelt <>
     * @since 2013-08-04
    private $strings = array();

     * Super cool method with type hint for string
     * @author stev leibelt <>
     * @since 2013-08-04
    public function addString(\Net\Bazzline\Component\DataType\String $string)
        $this->strings[] = $string;

        return $this;

$myString = new \Net\Bazzline\Component\DataType\String('super cool test string');

$myClass = new MyClass();


  • Extend provided types with classes in own namespace.
  • If you add a super cool method to your type, push it and be a part of the development team

I started developing this component because of the many casts i have to do while dealing with php's basic data types. As general, i searched the web for existing and easy to use components but could not find them. If you find one, please tell me. Last but not least SplTypes are still experimental.

To Do

  • Cover existing unittest with validation of implemented interfaces
  • Can we use pack?
  • Add modulo to Numeric
  • Add locking (mark a value as read only)
  • Add Date type -> check Joda Time
  • Add Time type
  • Add DateTime type
  • Add arrayAccess to string
  • Add collection
  • Add examples
  • Add benchmarks
  • Option type?
  • Enum?
  • Add invoke to String?


Following are links i found and used for creating this component.

Other Implementations


  • next
    • Coverd existing classes with "ableInterface" where each defines a from$Type and to$Type method
    • Started class for array called DataArray
    • Implemented usage of LockInterface, now you can lock a datatype to prevent from value changes
  • 1.1.0
    • Updated readme
    • Implemented isEmpty method which leads to different behaviour while creating an object
  • 1.0.0
    • Finished data type Boolean
    • Finished data type FloatingPoint
    • Finished data type Numierc
    • Finished data type Integer
    • Finished data type String
