Repeat elements in preg_replace()

I have string:{$value.level-1.level-2.level-3 ... level-n} and i need to change it to {$value['level-1']['level-2']['level-3'] ... ['level-n']}.

I now how to make only for one:

preg_replace('(\{\$(.*?)\.(.*?)\})', '{$$1[\'$2\']}', $string); But how can i repeat it for all levels?

You don't need regex for this. For what you're trying to do, it's unnecessarily complicated, hard to read, and hard to maintain. Just use str_replace instead:

$leadinString = '$value'; // or '$test' or 'foobar' or whatever
$str = '{$value.level-1.level-2.level-3 ... level-n}';
echo str_replace(array("$leadinString.", '}', '.'), array($leadinString . "['", "']", "']['"), $str);

Try this:

preg_replace('#\.([a-zA-Z0-9_-]+)#', '[\'$1\']', $string)
