I had the same problem this past weekend when I upgraded Apache, PHP and
MySQL on another computer. I made the mistake of using the .msi package
(Windows Installer) for PHP 5.2.5. Several necessary items were missing.
After Googling for a solution, I went to php.net and downloaded the
latest package (5.2.6) but made sure I grabbed the zip file. Once
downloaded, I unzipped the package and moved php_mbstring.dll (and a
couple of others) to the ext folder. I had already added the missing
extension=php_mbstring.dll to php.ini. Once I did that, it worked fine.

If you prefer, just download the 5.2.6 zip file (make sure it's the zip
file) and do a full install that way.
