$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)
{
}

Subject: [PHP] Confused About Classes
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.
?php
class standardquestion
{
var $private;
function standardquestion($xmlfilename)
{
$this-private=FALSE;
$parser=xml_parser_create();
xml_set_element_handler($parser,
array(standardquestion,startElementHandler),
array(standardquestion,endElementHandler));
while ($data = fread($fp, 4096))
{
if (!xml_parse($parser, $data, feof($fp)))
{
die(sprintf(XML error %d %d,
xml_get_currentnode_line_number($parser),
xml_get_currentnode_column_number($parser)));
}
}
}
function startElementHandler($parser, $name, $attribs)
{
if ($name==private)
$this-private = TRUE;
if ($this-private==FALSE) // Undefined variable this
return;
}
function endElementHandler($parser, $name)
{
}
}

Re: [PHP] Confused About Classes
No, the only thing I supplied is the class. The startElementHandler IS a
function in the class.

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.
