You can do anything you want... :)

<?php

class StrictProps
{
    private $___init = true;

    function StrictProps( $props )
    {
        $propsList = func_get_args();

        foreach( $propsList as $props )
        {
            if( is_array( $props ) )
            {
                foreach( $props as $prop => $init )
                {
                    $this->{$prop} = $init;
                }
            }
            else
            {
                $this->{$props} = null;
            }
        }

        $this->___init = false;
    }

    function __set( $name, $value )
    {
        if( !$this->___init )
        {
            die( 'Attempt to set non-existent property: '
                .get_class( $this ).'->'.$name."\n" );
        }

        $this->{$name} = $value;
    }

    function __get( $name )
    {
        die( 'Attempt to get non-existent property: '
            .get_class( $this ).'->'.$name."\n" );
    }
}

//
// Declare strict properties...
//
$my = new StrictProps( 'foo', 'fee', 'fii' );
print_r( $my );

//
// Declare and intialize strict properties...
//
$my = new StrictProps( array( 'foo' => 'Foo1', 'fee' => 'Fee1' ) );
print_r( $my );

echo $my->foo."\n";
echo $my->fee."\n";
echo $my->blah."\n";

?>
