im trying to use preg_replace to output the following situations.
only letters
only numbers
only letters and numbers
only letters numbers periods and commas

im trying also trim all white spaces, i guess i can use trim() unless there is a way i can use regex to trim all down in one function.

so far i got only numbers down
preg_replace("#[^0-9]#i",' ',$var)
