Another proposed version was in ​https://sourceforge.net/tracker/index.php?func=detail&aid=1109049&group_id=75348&atid=543655

Introduced visibility specifiers (private, public) for member variables and methods.
Fixed XHTML validity (slash at the end of input tag).
Code style (indenting, one-true brackets etc.) adjusted to PEAR coding standards, as well as naming of variables and methods (first char in lowercase).
