PHP Regex replace an entire string that differs a little

Question

I am trying to replace an entire string in a file.

$db['default']['hostname'] = 'localhost';

I want to do a preg_replace the entire string, even the variable. Im having trouble matching it with the RegEx. I have this so far:

preg_match("/\$db\['default'\]\['hostname'\]^;");

But what Im trying to do is find the entire line and completely replace it with something else. So the Regex would be like:

"^$db['default']['hostname'](AnythingHere);$"

Does anyone know the character group I accomplish that?

This one worked on RegexPal:

(\$db\[\'default']\['hostname'])( = 'localhost')(;)

And the replace string should be:

\1(AnythingHere)\2

+1 for a working solution. You could also use non-matching look-ahead patterns for the bits that aren't going to be replaced.
