i had problem that if i declare private variable getting session value by $this->session->userdata(). if just a nomol string it ok

private $table = 'contact'; // Work

private $my_prefix = $this->session->userdata('my_prefix');

Expressions are not allowed as default values, which is also why you cannot set a property to a default value of 1+1 either, you would have to set it to 2. However you should be able to set the value in a constructor though. Try this

Class Foo {
    private $my_prefix = '';
    function __construct() {
        $this->my_prefix = $this->session->userdata('my_prefix'); 
    }
}

In the above code I am assuming the Foo object has access to codeigniters global $this object

For more information this stackoverflow page does a good job of explaining it Class - variable declaration
