A common pitfall of child classes is that, if your parent and child both contain a constructor(__construct()) method, only the child class constructor will run. There may be occasions where you need to run the parent __construct() method from it’s child. If you need to do that, then you will need to use the parent:: scope resolutor:
parent::__construct();Now harnessing that within a real-world situation would look something like:
class Foo {
function __construct($args) {
echo 'parent';
}
}
class Bar extends Foo {
function __construct($args) {
parent::__construct($args);
}
}The above will run the parent __construct() resulting in the echo being run.
