Here's my test:

class foo extends GtkWindow {
    function foo() {
        $this->hash['foo'] = array();

        var_dump( $this->hash[ 'foo']); // NULL
        $test = $this->hash;
        var_dump( $test[ 'foo']);       // NULL, too, its ok

        if( isset( $test[ 'foo'])) {    // works, doesn't enter the if
            print 'isset( $test[ \'foo\']) worked'."\n";
        }

        // but

        if( isset( $this->hash[ 'foo'])) { // enters the if here
            print 'isset( $this->hash[ \'foo\']) worked'."\n";
        }

    }
}

$obj = new foo;

The result:

array(0) {
}
array(0) {
}
isset( $test[ 'foo']) worked
isset( $this->hash[ 'foo']) worked

So it works.
