Does anybody know a FREE Webhost who supports PHP and MySQL and offers much MB?I don't remember exactly what's offered, nor the conditions, but I do remember that Lycos (there are several localised versions) provide free hosting with PHP and MySQL support.
Make sure you read the small print before committing (though that's true in any case). Many free hosts place minimum hit frequency constraints on free accounts. If you don't get X hits within a certain period, your account is removed.
