Question

I’ve got the following problem.

When a form is submitted using ajax I need to check a few of the POST-variables if they contain the special characters æ, ø and å (as well as uppercase Æ Ø Å). Say I have 100 POST-variables, I really only care about a few of them (say firstname, lastname and adress). If it contains these letters the content of the variable should be utf8_encoded.

How can this be done in a nice dynamic way? I need to be able to change what variables I am checking easily (I guess the best way is to store this in an array).

Are there any neat ways to do this, or do I have to have a mess of loops in order to accomplish this?

This might help:

$str = 'áéóú';
mb_detect_encoding($str, 'UTF-8', true); // false
