PHP somo la 67: Project ya CUDE operaton wa utuma OOP na PDO
Katika somo hii utakwenda kujifunza jinsi ya kufanya CRUDE operation kwa kutumia PDO. crude operation inahusu create, read, update. Delete.
Database ambayo tunakwend akuitumia ni ileile ya wanafunzi. Ila ongeza table nyingine iite majibu. Table hiyo iwe na column 3 ambazo ni id, jina, alama. Hakikisha column id ni autoincrement..
Project yetu tauwa na mfali 6 ambayo ni
- Add.php
- Delete.php
- Edit.php
- index.php
- Style.css
- Wanafnzi_class.php.
Kama nilivyo eleza kwene somo lilotanguliwa kuwa tutatumia mfumo wa OOP yaani object oriented programming. Hivyo kama utarejea project yetu ya CRUDE operation kwa kutumia OOP unaweza kuelewa zaidi.
