[RESOLVED] Let user change a constant variable

Copy linkTweet thisAlerts:

I have a constant variable in a php page. Its a threshold variable. I have manually set it to an initial amount. However, the customer request a way to change the threshold when they see fit.

I know of one way to get this done: Store the values in a database and read it every time the script runs. I would rather not do this.

Is it a good idea to write the value to a config file and read that. Is it a bad idea to write directly to the php file?

Either a file or data base would work just fine for what you need to do. Files solutions could be a simple txt file or an ini, this is handy for that kind of thing. http://us2.php.net/manual/en/function.parse-ini-file.php but file() would be just as easy.

Thanks.

Success!
