1.2.579. Instantiating Abstract Class¶
PHP cannot instantiate an abstract class.
The classes are actually abstract classes, and should be derived into a concrete class to be instantiated.
<?php
abstract class Foo {
protected $a;
}
class Bar extends Foo {
protected $b;
}
// instantiating a concrete class.
new Bar();
// instantiating an abstract class.
// In real life, this is not possible also because the definition and the instantiation are in the same file
new Foo();
?>
See also Class Abstraction.
1.2.579.1. Suggestions¶
Make the class non abstract
Extends that class with a new class that is not abstract. Instantiate that second class.
Find an existing concrete class
