How to change data from php to config file

You could make a config template with replaceable parameters and then do a str_replace on them
when finished just move the template to the config folder.

You could also do that for the database config.

Thanks, i think i got the idea.
Like that ?

PHP Code:

$configText = file_get_contents("writable/template/Config.php");
$configText = str_replace("{someVar}", $userInput, $configText);

file_put_contents("Config/CustomConfig.php", $configText);
