What can I add in constructors in PHP?

• Could anyone tell me what I can include in the constructor? I know that I can do the following. function __construct(){ parent::Controller(); session_start(); } But I am wondering if I can add any variables, if statement etc. Thanks in advance.

• Answer:

  You can include variables, function calls, method calls, object declarations, etc, etc, etc inside your default constructor. class Test { protected $protected; private static $static; function __construct() { parent::__construct(); $this->protected = 'test'; $variable_local = 'hey'; self::$static = 'im static'; $obj = new OtherClass(); $this->myMethod(); externalFunction(); } public function myMethod() { echo 'all mine'; } } function externalFunction() { 'hey, im external'; }
