RE: [PHP] Confused About Classes
However, startElementHandler() is not be called in a class context.
According to the manual for xml_set_element_handler():
"There is currently no support for object/method handlers."

No, the only thing I supplied is the class. The startElementHandler IS a
function in the class.

$this is relevant ONLY within the scope of the class definition.
The above snippet is located OUTSIDE of the class definition.
You must use an object pointer. That is:
$newobj = new standardquestion($filename);
if( $newobj->private==FALSE)
{
}

I am getting the error "Undefined variable this" in my class. I am new to
PHP and presume I am just doing something wrong. But, I don't understand
what it could be as the code looks straightforward to me. Note that I
trimmed out some code to keep this listing from being huge, but the relevant
pieces are included.

$parser=xml_parser_create();
xml_set_element_handler($parser,
