print_r($val->getName() . "<P>");

}
?>

The first print_r works, it produces an array of methods including
"getName".

The second print_r works, it produces the value of $val->name being
"Whatever" or something.

The third print_r fails, and here is the error:

Fatal error: Call to a member function on a non-object in
/var/www/html/development/phillip/libdev/formvalidation. inc on line
150

I am totally baffled as to this behavior because it makes absolutely
no sense to me, no matter what I have read about classes, this makes
no sense at all. How can a class object suddenly NOT become an object
by the next line?

Hi Phil!

(...)

function isValid() {
foreach ($this->errorMsgObjArr ay as $key => $val) {
print_r(get_cla ss_methods($val )); print_r("<P>");
print_r($val->name . "<P>");
print_r($val->getName() . "<P>");
}
return $this->isValid;
}

}
?>

The first print_r works, it produces an array of methods including
"getName".

The second print_r works, it produces the value of $val->name being
"Whatever" or something.

The third print_r fails, and here is the error:

Fatal error: Call to a member function on a non-object in

by the next line?

It doesn't have to be an object in the second line. If it is not
defined at this point, PHP will create one with name as a property.

Try

error-reporting(E_ALL );, this may give you an undefined property on
the second one.

And print_r ($val);
