Write Data To File

[The_PHP_Newb]

Is it possible to write data from a form to a .php file vs. a .txt (like using fopen/fwrite/fclose).

I'm writing an installation program for a software piece and I'd like my customers to be able to enter thier /path/ data (into the config.php file) using a form vs. manually editing the .php file.

If so, could someone please provide a sample snippet?

Thanks.

A .php file is a textfile.
With a little tweaking, you could get .txt files to be interpreted as php as well.

It depends on your implementation.
How is config.php structured?
