Question

I am trying to store objects in session

However, when I do the following, I don’t get output as expected

Code:

In the session am storing objects like this –

    $oEmployee = new Employee();
    $_SESSION['Employee'] = $oEmployee;

And am trying to print like this –

    print_r($_SESSION['Employee']);
    echo "<br>";
    $oEmployee = new $_SESSION['Employee'];
    print_r($oEmployee);

This is the output I am getting:

    Employee Object
    (
       [m_sFirstName:private] => Sac
       [m_sLastName:private] => Kos
       [m_sPhone:private] => 9876543210
       [m_sEmail:private] => [e-mail]
       [m_sPassword:private] => password
       [m_iEmployeeId:private] => 1 
    )

    Employee Object
    (
       [m_sFirstName:private] => 
       [m_sLastName:private] => 
       [m_sPhone:private] => 
       [m_sEmail:private] => 
       [m_sPassword:private] => 
    )

Any idea what’s going wrong ?

Answer 1

The problem lies with your line

$oEmployee = new $_SESSION['Employee'];

PHP casts the value in $_SESSION['Employee'] to string, and then tries to instantiate a class with that name (new). Since you aren’t passing anything to the constructor, an empty object is instantiated.

What are you trying to do in that line?
