I have tried:

<?
class start_vars_list {
    var $first_name;
    var $last_name;
    var $company;
}

$vars = get_class_vars(start_vars_list);
echo $vars[1];

?>

$vars is an array, but contains no data. I was thinking that echo $vars[1];
should give me "last_name" but it does not return anything.

well, if you don?t initialize your variable with some value, get_class_vars() won?t return anything

var $f='set';

will work,
anyway in the case of CLASSES it could make sense that variables that aren?t initialized and listed instead with

var $f;

are returned too, *but* that would require significant changes, or another function like get_unitialized_class_vars() or sth. else, because var_dump() cannot display something that is between NULL and sth.

I think this only can be turned into a feature request (if possible at all, not sure) using another function, or a parameter for the current function

comments anyone?

Hmmm... Perhaps I am just missing something here, but the following does not return anything either:

<?
class start_vars_list { 

    var $first_name='1'; 
    var $last_name='2'; 
    var $company='3';
} 

$vars = get_class_vars(start_vars_list);
echo $vars[1];

?>

Run var_dump($vars). See the result.

Please do var_dump to the result of get_class_vars and see how it is organized.

did closing without comment imply variables without initialized value cannot be retrieved with another function OR it that it does not make sense?
