PHP language detection

Question

I\'m trying to build multilangual site.

I use this piece of code to detect users language. If you havent chosen a language, it will include your language file based

Answer 1

I know there already many good solutions, but have found my own way to solve this problem.

 float 1
      'en' => float 0.8
      'uk' => float 0.6
      'ru' => float 0.4
    */

Code will convert HTTP_ACCEPT_LANGUAGE string to array with locales as keys and weight as values, sorted from high value to low. So you can just get one by one with array_shift to get the best match with your site locales.
