Returning a value in constructor function of a class

Question

So far I have a PHP class with the constructor

public function __construct ($identifier = NULL)
{
 // Return me.
if ( $identifier != NULL )
{
           


        

Answer 1

The constructor is suppose to create an object. Since in php booleans are not considered to be objects the only option is null. Otherwise use a workaround i.e. write a static method which creates the actual object.

public static function CheckAndCreate($identifier){
  $result = self::loadUser();
  if($result === true){
    return new EmailClassNameHere();
  }else{
    return false;
  }
}
