Just to spice things up a bit. Now check this url - http://mwebng.net/bad.php
View the source code in the browser (it should validate as incomplete html), and click on the validation.
This shows that w3c validation can be beaten, but how did i do it? or what
are the possible ways?

dual core oya come and answer this quiz jor!

Ok o my oga!

This is just what I think.
You used the $_SERVER['HTTP_USER_AGENT'] variable to specify the right DOCTYPE that you want the validator to see.
You put this right at the top of the page. The validator will use the first user agent that was already checked.

can u give us a full example code? i think you have missed out something.

hmmm, after my garri and epa.
