Hi,
Hope you can help me out with this one..
nl2br($string) converts all the \n to <br \>
... but ..
Suppose I have a table or other HTML elements in $string..
All the TD> and TR> and FORM> are trailed by <br />
How can I adjust the function:
preg_replace("/\r\n|\r|\n/", "<br>\n", $r[body])
to ignore lines ending with >
(or: > n spaces )
Thanx in advance,
Marco Snoek

I think you're heading into trouble with this approach; what about the
following perfectly valid HTML:
<form method="get"
action="somethi ng.php"
name="whatever" >
You've now got a whole load of other exceptions to deal with.
The idea of nl2br is to convert _non-HTML_ text data containing newlines to an
HTML equivalent that has <br> elements so that it has newlines in the same
place when inserted into an HTML document.
In general, you can't parse HTML with a single regular expression, as regular
expressions aren't capable of maintaining states as necessary to implement a
HTML parser.

You're absolutely right..

I'm quite sure the trick should work.. I enter the input myself :-)
Can you think of a reg_exp ???

You need the "lookbehind " stuff.
Open this URLi: http://www.php.net/manual/en/pcre.pattern.syntax.php
and search "lookbehind " in that page

Hey all,
So I started using nl2br and love it. But when I convert back from
<br> to \n, it produces double spaces instead of single space.
Converting \n to <br>:
$emailBody=nl2br($_POST);
$emailBody=str_replace("<br />", "<br>", "$emailBody");

Hi all,
I'm looking for a way to scan a block of text and replace all the

I'm using PHP to pull text out of a mySQL table and then feed the text
into a javascript function called by onClick. The problem is that the
text may contain single or double quotes, which screws up the
javascript. I eliminated the single quote problem by running the text
through addslashes, but the double quotes are a...

$a = $_POST; # txt_content = This is a<CR><LF>Test
$p = str_replace ("%0D%0A", "<br>", $a);
That is the above code that I am using, however, it is not picking up
the CR/LF from the textarea. I have also attempted singular variations
of the CR/LF combination and even reversed the sequence without success.
Is it possible that it may be encoded differently and if so what is it?
Thanks

Ok, I want to disable any html tags, but the problem is when I do add in the nl2br function with a htmlentities it displays the tags for the <br>! I even keep seeing rn every time I enter a return in that area from the textarea html command. So how do I have nl2br going and htmlentities going at the same time, but not having to disabling each other?

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
