in reply to Quickie regular expression question.

the some reason is that you are not using code-tags.

As for your question, your code only checks for a single occurence of a digit/letter. Change it to 
if ($newpasswd !~ /^[A-Za-z0-9]+$/) 
{
#EXECUTE SOME THINGS;
}

or even 
if ($newpasswd !~ /^[\w\d]+$/) 
{
#EXECUTE SOME THINGS;
}

    [\w\d] is a much bigger set.
    It includes "_" and the chinese character for "one", for example.

    [:alnum:] would be better than \w\d as that's strictly alphanumerics and should respect locale as well.
