[snip]
The square brackets simply form a group of characters that are either
allowed ('[abc]') or not allowed ('[^abc]').
Instead of specifying '/[a-zA-Z]/' you have also the option of saying
'/[a-z]/i', the i modifier making the whole regex case independent.
For deeper regex insights (esp. for the preg_xxx functions which I
personally prefer) I suggest visiting the Perl docs at
Doc:http://www.perldoc.com/perl5.8.0/pod/perlre.html
QuickIntro: http://www.perldoc.com/perl5.8.0/pod/perlrequick.html
Tutorial: http://www.perldoc.com/perl5.8.0/pod/perlretut.html
For the PHP guyz'n gals listening - I suggest these links making it into
the PHP docs :)

Thanks so much!!! It works. I didn't know I could also place extra
characters inside the brackets to specify what I want. :)

use
preg_match('/^[a-zA-Z\s]+$/', $text);
\s - any [:space:]
\S - anything not [:space:]
