Question

Hello there i’ve finally made a good perfect language system and now am trying to fix my templates system to work with this new language system =P
i want to replace to $tag[‘$thepreviousvalue’] so i made the following code

preg_replace("/<LANGUAGE value=\"^[a-zA-Z0-9_]{1,}$\">/si", ''. $langvals['$1'] .'', $data);

but it doesn’t work and i bet that my weak knowledge in regexp is the problem.

Answer 1

preg_replace('/your_regex/e', '$var[\'$1\']', $string);

In your case:

preg_replace('/<LANGUAGE value="([a-z0-9_]+?)">/ei', '$langvals[\'$1\']', $data);

You can read more about the “e” modifier at php.net.

Also, I fixed your regex.
