Zend Framework 2 : Dependency Injection
This document discusses dependency injection in Zend Framework 2. It defines dependency injection as components being given their dependencies through constructors, methods, or directly into fields. It provides examples of constructor injection, setter injection, and interface injection in PHP code. It also shows how Zend Framework's dependency injection component can be used to configure dependency injection and resolve dependencies and examples of using the setter method for dependency injection.

- 5. -‐ DEPENDENCY INJECTION TERJADI KETIKA KOMPONEN SOFTWARE ( DALAM HAL INI, KELAS ) DEPENDENSINYA DIBERIKAN MELALUI KONSTRUKTOR MEREKA, METHOD, ATAU LANGSUNG KE FIELDS
- 6. => PASSING ATAU SETTING DEPENDENCY KE DALAM KOMPONEN SOFTWARE => JIKA SEBUAH KELAS TIDAK DAPAT MELAKUKAN PEKERJAANNYA TANPA DEPENDENCY, MAKA TERJADILAH DEPENDENCY INJECTION
- 7. -‐ CONSTRUCTOR INJECTION -‐ SETTER INJECTION -‐ INTERFACE INJECTION
- 8. CONSTRUCTOR INJECTION class Kalimat { protected $filterstring; public funcGon __construct(FilterString $filterstring ) { $this-‐>filterstring = $filterstring ; } }
- 9. SETTER INJECTION class Kalimat { protected $filterstring; public funcGon setFilterString(FilterString $filterstring ) { $this-‐>filterstring = $filterstring ; } }
- 10. INTERFACE INJECTION interface Kalimat { public funcGon setFilter(FilterString $filterstring); }
- 11. 2 KELAS ( SAMPLE )….
- 12. <?php class FilterString { protected $str; public funcGon __construct($str) { $this-‐>str = ucfirst( str_replace(" ","_", $str) ); } public funcGon get() { return $this-‐>str; } }
- 13. <?php class Kalimat { protected $filterstring; public funcGon __construct(FilterString $filterstring) { $this-‐>filterstring = $filterstring; } public funcGon out() { echo 'ouGng .... -‐> '; echo $this-‐>filterstring-‐>get(); } }
- 14. TANPA ZENDDI <?php $filter = new FilterString('saya sedang membaca'); $kalimat = new Kalimat($filter); $kalimat-‐>out();

- 17. <?php $di = new ZendDiDi; $di-‐>instanceManager() -‐>setParameters('FilterString', array( 'str' => 'saya sedang membaca’ )); $kalimat = $di-‐>get('Kalimat'); //contains FilterString ! $kalimat-‐>out();

- 19. …………… public funcGon setFilterString(FilterString $filterstring) { $this-‐>filterstring = $filterstring; }
- 20. $di = new ZendDiDi(); $di-‐>configure(new ZendDiConfiguraGon(array( 'definiGon' => array( 'class' => array( 'Kalimat' => array( 'setFilterString' => array('required' => true) ) ) ) ))); $kalimat = $di-‐>get('Kalimat', array( 'str'=>'saya sedang membaca' ) ); $kalimat-‐>out();
