Reading and Writing Configuration Files

Okay, I have a config file, which contains some information that I would like the user to be able to change. I've already thought about holding the information in a MySQL table but this isn't a good idea as I've got my Database class included AFTER my configuration variables and this would mess up my code structure.

Any idea how to read/write variables/specific lines of a file? Here's my global config file.>

error_reporting(E_ALL);

/*
    The parameters used site-wide
    First set are Datbase parameters
    And second set are the salts used to generate strings
*/
$params['db']['host'] = 'localhost';
$params['db']['username'] = 'root';
$params['db']['password'] = 'waffliner';
$params['db']['db_name'] = 'habcms';

$params ['core']['salt1'] = "184962574320355793361124913390";
$params['core']['salt2'] = "13952134426315134482857516025";

$params['core']['timeout'] = "60 minutes";


try {
    include_once("core.inc.php");
    include_once("db.inc.php");
    include_once("user.inc.php");       
} catch(exception $e) {
    echo $e->getMessag开发者_StackOverflow中文版e();
}

?>

JSON♥ is your friend.

{
    "db": {
        "host" : "localhost",
        "username" : "root"
        ...
    },
    ...
}

If you want to do so, you need to store you configuration in a non-PHP file.

You can, for example, store your config in an .ini file and read it with parse_ini_file().
