The documentation for Unset() states:
Description
int unset (mixed var [, mixed var [, ...]])
unset() destroys the specified variables and returns true. 

I have changed the type of this bug report to "Documentation Problem", since I have been informed that Unset is not a function. 

<?
$avariable = "test";
$avariable=="test" ? $avariable .=" No problem with is_bool" :
is_bool($avariable);
$avariable=="test" ? $avariable .=" No problem with isset" :
isset($avariable);
$avariable=="test" ? $avariable .=" No problem with empty" :
empty($avariable);
$avariable=="test" ? $avariable .=" Problem with unset" :
unset($avariable);
echo $avariable;
?>

Output is
Parse error: parse error in /home/httpd/html/mlr/unsetProblem.php on line 6
