help finding php information and how to turn on error reporting?

Hi All,

i know there is a way to display all the information about my setup, think you have to create a text file with something in it like php info or something which when run it displays all the data???

also if needed how do i turn on global error reporting, think my host turned it off when upgrading the php version

many thanks
Luke
