check input char

[deep]

Hello!

What's the best way to check if an input variable $input contains a char between a-ö (thats a-z plus å ä ö)? (and only 1 char, no more 😃 )

Thanks!

in_array() might be a good place to start.

Or [man]strpos[/man] if you've got all the characters in a string instead of an array.
