[RESOLVED] How? Read all variable names of a file into an array

[sherry]

Hello.

Is it possible to read in all of the variable names found in a single file e.g. from a config file and place them into an array?

Thanks.

[dagon]

yes, but why not do it in the config in the first place?

Thanks for your reply, dagon.

Please elaborate.

The values are there. It would be nice to read them into an array in order to easily put them into the namespace of functions since extract($GLOBALS) have been discouraged for usage for security reasons.

Thanks.

One way would be to not use variables in the config file in the first place (at least, not individual variables). Either use constants, or use a single variable, e.g. $CONFIG, as an array of 'config' values (which you could then use inside functions by bringing the $CONFIG variable into scope).

And of course, NogDog's suggestion in your other thread still applies - you could consider building an object instead that holds all of the config attributes.

Thanks for your reply, bradgrafelman.

Prior to your reply, I did create an array of each of the vars. I was going to add that to this thread, but you beat me to the punch!

I really like your suggestion regarding creating constants and NogDog's object suggestion. I will try those also.

Thanks again!
