[PHP] Simple RegExp Problem...
Hello, Ok, I know this is easy for most of you, and believe me I've been searching and trying to learn all about regular expressions, but I can't seem figure out how to allow addition of spaces between characters. $text = Here is some text; Here, I want to be able to match the alpha characters as well as the spaces in between each word. So far I have: preg_match(/^[a-zA-Z]+$/, $text); But that only matches a single word without spaces. I would like to try to stay away from ereg and use preg_match instead because I heard preg_match is faster. ereg() has a way to match spaces by specifying [[:space:]], but I didn't get that solution to work either. How do I match $text to return true? - Nilaab -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

use

\s - any [:space:]
\S - anything not [:space:]

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

[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 :)
