PHP abstract properties

Question

Is there any way to define abstract class properties in PHP?

abstract class Foo_Abstract {
    abstract public $tablename;
}

class Foo extends Foo_Abstract          


        

Answer 1

As you could have found out by just testing your code:

Fatal error: Properties cannot be declared abstract in ... on line 3

No, there is not. Properties cannot be declared abstract in PHP.

However you can implement a getter/setter function abstract, this might be what you're looking for.

Properties aren't implemented (especially public properties), they just exist (or not):

$foo = new Foo;
$foo->publicProperty = 'Bar';
