Example of a php abstract class to learn how to implement a php abstract class
// Define an abstract class - Abstract class Staff
- {
- Abstract function hire ();
- Abstract function fire ();
- Abstract function promote ();
- Abstract function demote ();
- }
?> Example 2: php abstract class
Class Employee { - Private $ title;
