The following source returns "Parse error: parse error, unexpected '(', expecting ',' or ')' in [...]/bug.php on line 24".

<?php

   class MyClass
   {
      function myFunction($arg)
      {
         return $arg;
      }
   }

   $c = new MyClass;

   // works

   $v = $c->myFunction('foo');

   if( empty( $v ) )
      print "test-1: empty";
   else
      print "test-1: not empty";

   // don't work

   if( empty( $c->myFunction('foo') ) ) // this is the problem
      print "test-2: empty";
   else
      print "test-2: not empty";
?>

empty() can be replaced with same result with isset(). The

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Oops :) Wrong text :)

Please read http://www.php.net/manual/en/function.empty.php too, which says:

 Note that this is meaningless when used on anything which isn't a variable; i.e. empty (addslashes ($name)) has no meaning since it would be checking whether something which isn't a variable is a variable with a FALSE value.
