There's a table I download from the MySql database very frequently.
Rather than download it every single time, I was hoping I could some how declare a paricular object as "global" and "persistant". So it downloads it from MySql the first time, keeps it in memory, and subsequent calls to the page just use the local memory copy rather than make another database call.
Refreshing the memory resident copy could be manually forced from a sysadmin page as required.
Is this possible in PHP? (I don't really want to hard code the table into an include file, since this table is used on other SQL queries)
