Hey guess what? Actually lots of webhosts are offering PHP 5.3.x as an option nowadays but most people do not realize it is there.
But yeah I wont blame the users for not knowing since the webhosts apparently aint heavily promoting PHP 5.3.x by using a gigantic banner to notice them. It seems that we may be able to use namespace and other amazing stuff from PHP 5.3 very soon, isnt this good news?
