I'm working on a php script that has to load some data from a file before it can run. problem is, it's loading the data every time the script runs. is there a way to load it once and somehow keep the data in memory? basically the user is giving the script multiple commands, but each time the script processes the command it has to reload the data file. I want to load once, then give a console-like command prompt. can this be done with PHP, or am I going to be rewriting this in perl?
