PhP -> Line break

[Massacres]

\n in double qoutes [i]should [/i]work, but it doesn't seem to be working.

[code]<?php
$TF=array("False","True");
echo $TF[("hello"==="hello")];
?>

_blahblah_

<?php
echo "\n",$TF[0];
?>[/code]

Unless you are enclosing the line breaks within PRE tags, it will not be displayed as a line break on the page. It will be a line break in the HTML code. You need to echo < BR > tags to the page to make "displayed" line breaks.

It does work. But only in the source code. The reason for this becuase the browser ignores whitespace characters, such a \n \r \t etc. However if you go to View > Source in the browser you'll see that the whitespace characters have been parsed.

What you'll need to do is is convert the line breaks to HTML line breaks [nobbc]<br />[/nobbc]. You can easily do this using the nl2br function.:
[code=php:0]$someStr = 'this has \r\nnewlines \ncha\n\n\nrac\nters in \it!';

// display $someStr without nlsbr function:
echo $someStr . '<hr />';

// display $someStr with nl2br function:
echo nl2br($someStr);[/code]

EDIT2: I got the hunch that maybe I could use the HTML linebreak ( <br> ) and it worked, so I guess I misread your post. Thank you, this is very helpful.

It didn't work; or I'm missing something;

[color=red][b]Input:[/b][/color]
[code]<?php
$someStr = 'this has \r\nnewlines \ncha\n\n\nrac\nters in \it!';
echo nl2br($someStr);
?>[/code]

[color=red][b]Output[/b][/color]
this has \r\nnewlines \ncha\n\n\nrac\nters in \it!

EDIT: Didn't mean to send so soon >_<

It displays '\n', it just doesn't use it as a linebreak =/

That's because it's enclosed in single quotes.

The escape characters only work inside double quotes.

Oh crap!! Yeah whitespace characters only work in double quotes.This should work for you:

[code=php:0]<?php
$someStr = "this has \r\nnewlines \ncha\n\n\nrac\nters in \it!";
echo nl2br($someStr);
?>[/code]
