PHP templating using custom code replacing using regex

Question

How can I convert {$game.name.fullname} to $game[\'name\'][\'fullname\'] using regex.

thanks

Answer 1

preg_replace(
    '/{\$([^.{}]*)\.([^.{}]*)\.([^.{}]*)}/',
    '$$1[\'$2\'][\'$3\']',
    '{$game.name.fullname}');

Edit: Edited according to ridgerunner's comment. Now matches anything between dots and matches multiple strings.
