Question

I implemented a class like this:

class ClassRoom
{
  public $desired_connection;  // variable of type DesiredConnection

  //Constructor
  public function __contruct()
  {
    $this->desired_connection = new DesiredConnection(); //Initialize
  }

  public function save(){   
    //Save Desired Connection
    $this->desired_connection->saveDesiredConnection();  
  }
}

Upon calling $classroom->save(), runtime does not recognize $this->desired_connection as DesiredConnection object and throws this error:

“Call to a member function save() on a non-object.”

When I output, gettype($classroom->desired_connection), it outputs NULL.

Any suggestions on what I may be doing wrong here ?

Answer 1

Make sure your __construct function is named appropriately:

public function __construct() {
  // ...
}

PHP will only recognize magic functions that match the names it’s looking for!
