Well, chop() is an alias of rtrim(), so it won't work here for, say,
trimming control characters at the end of the string like line feeds.
trim() is actually the best bit here.

There is always using substr to mimic the Perl chomp() function. Look thru

of doing it.
Or just use trim() :-)

From usability point of view such check will, in many cases, generate annoyance, and bring nothing. If I do not want to enter anything, and you "error me" to enter "something", I'll do like this - asdlöfjasdpoöfja spdfj as fsdaölkjf And your check is dead. If you want "something", you will get "something". It is hard (from usability point of view) to "validate" textarea to that extent, and especially - to get reasonable answers... I work for a scientific database, where all content providers are very intelligent, well educated and very disciplined, and the content editors still have hard time thinking how to guide the content provider so that they provide reasonable input.

Actually trim() is probably less efficient since both ends of the string
will be examined whereas a string containing entirely whitespace
characters will rtrim() (chop() if you will) to an empty string also but
the second side won't need to be examined (even if only to check for 0
length).
But maybe you didn't realize this because your assertion was wrong in
the first place:
> so it won't work here for, say, trimming control characters at the
> end of the string like line feeds.
When clearly looking at the online documentation for rtrim() we see:
This function returns a string with whitespace stripped from
the end of str .
Without the second parameter, rtrim() will strip these characters:
" "(ASCII 32 (0x20)), an ordinary space.
"\t" (ASCII 9 (0x09)), a tab.
"\n" (ASCII 10 (0x0A)), a new line (line feed).
"\r" (ASCII 13 (0x0D)), a carriage return.
"\0" (ASCII 0 (0x00)), the NUL-byte.
"\x0B" (ASCII 11 (0x0B)), a vertical tab.
Cheers,
Rob.

You really should use htmlspecialchars before showing any user
stipulated HTML to help prevent security holes. Also you can use short
tags (popular...) to make the HTML more readable. Eg:

You should not rely on register_globals, and use either $_GET or $_POST
instead depending on which methoed to send your form details back to the
server. Eg:
if($_POST['comments'] == '' ) {
...
}

You can use the trim() function to determine whether a variable is just
whitespace.
$comments = trim($_POST['comments']);
if ($comments == '') {
// Show error message
}

One thing you might consider is, first of all, there are many characters which do not print and spaces are one of them, but from a computer standpoint they are characters, tabs and new lines are some others, the list goes on. For this specific case you can trim the results and that often will eliminate most of these if they appear at either end of what was typed, in this case the entire thing.

PHP is sevrer sided. So if you want to check if a user provided the
textarea with input. You have to submit the page. and let PHP do the magic.
If the textarea is not filled. You could send the user back to the form.
With an apropriat warning message.
It's probably easier to do it with client side javascript.
Check the contents of the textarea on submit and preform some actions
from there.
