best free web hosting with php 5.xxx,mysql and all php stuff enabled?

does anyone know a free web hosting service which has php v. 5.xxx and (almost) all php scripts work and mysql? i was using another host when i suddenly discovered that php barely works and mail() won't work at all...:(
so im looking for another host,it has to be free,ads-free and as many benefits as possible...
promise to give a best answer to the one that gives me the best hosting !!!

ps:if this question seems like a deja-vu (sorry if i misspelled it) you are right,i posted another question like this yesterday,but no one answered...here it is:
