how to remove multiple line breaks?

[Jon LaRosa]

I'm am trying to remove multiple line breaks ("\n"). Here's my code:

$imageStr = trim($_POST['images']);
$imageStr = str_replace("\n\n", "\n", $imageStr);

----------

$_POST['images'] is a textarea field, and I am trying to remove extra
hard returns that a user types into the text area.

When I change the code to:
$imageStr = str_replace("\n", "%", $imageStr);
it works fine. So I know the function works and I have the right
character ("\n").

Anyone know what I'm doing wrong?
thanks much,

How do you know it's NOT working??

What happens if you do $imageStr = str_replace("\n\n", "%",
$imageStr);?

Do two "\n"s get replaced by one "%"?

$imageStr = trim($_POST['images']);
/* while there are double line breaks in $imageStr */
while (strpos($imageStr, "\n\n") !== false) {

/* replace one such double line break by a single one */ $imageStr = str_replace("\n\n", "\n", $imageStr);

}

$string=preg_replace('`[\r\n]+`',"\n",$string);

/* while there are double line breaks in $imageStr */
while (strpos($imageStr, "\n\n") !== false) {

IMHO it would be much easier to use a regular expression instead.

Oops: wrong comment. Should have been:

/* replace as many such double line breaks as possible
by a single one */

$imageStr = str_replace("\n\n", "\n", $imageStr);

}

Linefeeds coming from the browser are "\r\n", which is why your replacement
code doesn't work. Use the snippet from Justin.
