im going to upload my application to some free server you guys will see it and then give me your suggestions.
Erm, not sure that works by itself. Code is what most of us need to see.
If you are running this on localhost and don't need it on remote, why don't you run the script as PHP CLI? No need for cronjob or daemon.
is anybody familiar with any best and quick hosting providers??
There are hundreds of threads on DW about this.
