I'm in the middle of Chapter 14, Perl-compatible Regular Expressions.
On Page 444, the following pattern is offered to test for presence of non-whitespace characters in a string:
^\S$
If I'm interpreting the chapter correctly so far, in the form created for testing subjects against patterns, pcre.php, I should enter this code inside a pair of delimeters, like so:
/^\S$/
So, I've done that, and typed a string into the subject text area:
Testing for whitespace characters.
I received FALSE, so far so good.
Then I type simply:
testing
And I received FALSE again!
Suspecting that I may have messed up the code of pcre.php, I replaced my file with the one I downloaded from Larry's website. Ran the same two tests again, received same results.
Either I'm missing something, which I suspect is the case, or the pattern is incorrect.
Could someone please explain to me how to make it work or what I'm doing wrong?
