PHP Global Variables

by WarrenW Posted: 17 years ago 3 replies

I'm developing an e-commerce site involved with a lot of database access and naturally I want to keep the DB access to a minimum. Keeping some information in a server buffer definitely helps. I do have about 10 PHP script files for the entire site. Do you know if variables declared outside of functions in PHP modules are considered as global variables and accessible from any executing PHP scripts? Thanks,

Warren

If they are declared outside any functions or loops then yes, they'd be considered as global vars and could be used anywhere (as far as I know)
