[CodeIgniter] changing config.php by code

[eluser]BrianDHall[/eluser]
Ah what the hell, one more regex for the day:

Code:

// $file should contain full text of config.php

$key = 'index_page';
$new_value = '';

$search = '(\$config\[' . "'" . $key . "'" . '\] =)([^;])';
$replace = '\1"' . $new_value . '"';

$file = preg_replace("/$search/", $replace, $file);

Untested, but I think it should just about do it.

So $key is whatever config item you want to change the value of, and $new_value is what you want to set it to. And then that's it.

It's a place for you to start at least
