$a = $_POST['txt_content']; # 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

Carved in mystic runes upon the very living rock, the last words of
Wayne of comp.lang.php make plain: $a = $_POST['txt_content']; # 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.
Try $p = str_replace ("\r\n", "<br>", $a);
However, depending on what OS and/or browser your visitors use, a new
line character might be passed as CR, LF or CRLF. I usually do something
like:
$p = ereg_replace("\ r\n?" "\n", $a);
$p = str_replace("\n ", '<BR>', $p);
The first line makes sure they're all LFs before converting them to BRs.

Why you don't use nl2br function? It will returns string with '<br />'
inserted before all newlines.

Using the above, I transposed it to:
$p = ereg_replace ("/\r\n|\n\r|\r|\n/", "<br>", $p);
Thanks for your feedback and response.

- From what language did you come from? "%0D%0A" is not a valid syntax to
specify ascii characters in a string. Please have a read: http://es.php.net/manual/en/language....syntax.double
And, if you want to check for CR-LF, plus CR alone, plus LF alone, you may
want to pass an array to str_replace:
str_replace( array("\r\n","\ r","\n") , '<br>' , $subject);
Alternatively:
str_replace( array("\0x0d\0x 0a","\0x0d","\0 x0a") , '<br>' , $subject);
Alternatively:
str_replace( array(chr(13).c hr(10) , chr(13) , chr(10)) , '<br>' ,
$subject);
And, most important:
nl2br($subject) ;

Perhaps because it is incorrect syntax for other than XHTML. Apart from the fact that IE doesn't support it, other reasons not to use XHTML except for XML documents
I never heard about a case where <br /> did cause any problem... Anyway
this is still easier than regexps:
str_replace('<b r />', '<br>', nl2br($text));

I can think of a couple. For example, validation. <br /> means
something different in HTML than it does in XHTML. In HTML, '/' closes
the tag and '>' is treated literally. Not a big problem, maybe, but
probably not what you meant.
The point, I think, isn't that you are or aren't likely to run into
any problems, but rather that for interoperabilit y's sake you should
follow what the specs say - if not by the letter then at least in
spirit.

It is annoying though that nl2br() only returns <br /> Would it be so

I agree with both your points - in some cases I just prefer to go the
easy way as long as it can be expected to be supported by browsers for
the next few decades...
Actually it might be a good idea to introduce an ini setting or a
constant with the HTML version to generate for all kinds of HTML
generating functions.
Of course this will generate problems where text is post-processed, for
example double line breaks are changed to new paragraphs:
$text = nl2br($text);
$text = '<p>'.str_repla ce('<br /><br />', '</p><p>', $text).'</p>';
The str_replace needle will have be changed to nl2br("\n\n").
