HTML form element class object in PHP

Form Elements as easy as

$elem = new FormElement("yourElement", "Hello World Element");
echo $elem->HTML();

This Will print
--------------------------
<div class=''>Hello World Element</div>
<input id="yourElement" name="yourElement" type="text" form="form" onblur="Validate('yourElement')"/>
<div name='err' class='error'></div>
--------------------------
The last div named 'err' can be used to display errors from the validation.
