What I mean is say I make a form to set a few variables that I need saved in config.php how would I do this? For instance. In config.php it would be: $dbname = "" and when they go through the install it would need to set that as $dbname = "Form data" How would I do this please? +REP to helpers.
read up on the fopen, fclose, fread, fwrite, fget and fput functions at php.net... They are used to read and write files. There is nothing to stop you directly writing php files such as the config.php you mention. http://www.php.net/fopen
