Description:
------------
The current phpdoc of simplexml_load_file() on 
  http://de3.php.net/manual/en/function.simplexml-load-file.php 
says:
  object simplexml_load_file  (  string $filename  [,  string $class_name = "SimpleXMLElement"  [,  int $options = 0  [,  string $ns  [,  bool $is_prefix = false  ]]]] )

To aide auto-completion in IDEs it would be helpful if the documentation would
be changed to
  SimpleXMLElement simplexml_load_file(...)

At least NetBeans seems to auto generate stub .php files from the online documentation.
