For your filter to return only/no digits, I would recommend doing a bit of
reading on preg_replace ( http://us2.php.net/preg_replace ) while noting the
following flags:
\d
Matches any decimal digit; this is equivalent to the class [0-9].
\D
Matches any non-digit character; this is equivalent to the class [^0-9].
ex:
preg_replace('/\d/', '', $str);
preg_replace('/\D/', '', $str);

I would like to write a filter that takes the text "smith" or "SMith"
and returns "Smith"; same for "ralph smith". Is the a good source on
using filters this way?
It may not be the most efficient way of accomplishing this, but you
could do something like:
$string = 'SMith'
$fixedString = ucwords( strtolower( $string ));
thnx,
Chris
Thank you! I did not know about the ucwords() functions, and it does not
need the string set to lower case.
Now to create a filter that returns only numbers (e.g. "a1234z" -> "1234")
and the same for non-numbers.
Many thanks...
Todd
Thank you for the \d and \D suggestions! Another addition to my
tool chest.
