Easier:

 $tempanswer = preg_replace('/\s/', '', $answer);

The \s includes all white space, including line breaks.  You don't need
the *'s in there because all of them get replaced anyway.

[PHP] vertical word match

[Joe Rice]

hello,
any regex gurus?
i'm trying to match words put into a textarea
that are in the form of a\np\np\l\e
or any combination of new lines in between, before
or after.  

$answer = hello\na\np\np\nl\ne\n; /*from textarea in form*/
$word = apple;
$word = preg_replace(/(.)/,(.?|\s+|\n+|)$1(.?|\s+|\n+|),$word);
preg_match(/.$word./im,$answer,$match)

works.
but if

$word = red apple;
$answer = r\ne\nd\n\na\np\np\nl\e;

it doesn't match.


thanks in advance,
joe

try changing the +'s with *'s
+ = 1 or more
* = 0 or more
