I'll check this... BTW:
array explode ( string $delimiter, string $string [, int $limit] )
So, I was wrong...
The right way, probaly, is:
$str=explode(\n,$_POST[my_text]);
If it's coming from a textarea you'll want to use \r\n because a
textarea uses both a carriage return (\r) and newline (\n) to separate.
Otherwise each element of the array will have a \r on the end which
may end up causing you some issues later on.
I was wondering about this, I seem to recall that window/mac/*nix all do
it differently.
With a little Google'ing I came across this.
http://www.sitepoint.com/forums/printthread.php?t=54074
This was written in 2002, so I am not sure about the Mac = \r.
Since they are using *nix now, it could be \n not sure
But the article had this to say:
Line breaks
People want to know how they can retain textarea line breaks in HTML.
You should store text in the database in its original format (e.g. with
just newlines) and then use nl2br() to convert newlines to HTML br /
tags on display (thanks to the people here for teaching me that :)).
That's all good, except for one problem with nl2br(): it doesn't seem to
convert \r newlines (edit: this has now been fixed in PHP 4.2.0).
Windows uses \r\n newlines; *nix uses \n; Mac uses \r.
nl2br() works correctly on text from Windows/*nix because they contain
\n. However, if you get text from a Mac, nl2br() will not convert its
newlines (again, fixed in PHP 4.2.0). To remedy this, I use the
following bit of code to convert \r\n or \r to \n before inserting it
into the database. It won't hurt anything and ensures that nl2br() will
work on the \n only newlines on display. Also, it has the side effect of
saving 1 byte in the database per newline from Windows (by storing only
\n instead of \r\n). :)
PHP Code:
$txt = preg_replace('/\r\n|\r/', \n, $txt);
Fair enough :)
I guess my thinking was since a textarea is a html 'standard' it would
be consistent across all browsers/systems. I guess not :)

Another way to write that PCRE pattern is /\r\n?/ (one carriage
return followed by zero or one linefeed).
I recall also running into \n\r although I can't recall which system uses it.
As an alternative to PCRE, we can pass arrays to PHP's replace functions, e.g.:
$txt = str_replace(array(\r\n, \n\r, \r), \n, $txt);

Helped... =)
But... Why does it happen:
[code]
$object=mysql_fetch_object($result);
$texto = $object-texto;
$texto=preg_replace(/\r|\n/,,stripslashes($texto));
echo $texto;
[/code]
[output]
Teste
\r\nde formatação!
\r\nTudo funcionando...
\r\n
[/output]
I'm using stripslashse 'cause I'm getting the values from a DB.
Any kind of tip?
TIA
