[SOLVED] What does \r mean and what does \n mean?

[Sam Granger]

I have a question. At the moment, with my code I can post text into mysql. in my textarea however, if I type the following:

 

Hello.

 

Text goes here.

 

And a seperate paragraph here also!

 

I get the following when I view the text in my php page (simple query):

 

Hello. Text goes here. And a seperate paragraph here also!

 

As you can see, <enter> is changed into a space. However I want each <enter> equal a space. The MySQL looks like this:

Hello.\r\n\r\nText goes here.\r\n\r\nAnd a seperate paragraph here also!

 

Now, I assume I need to do something with str_replace. But what does \r mean and what does \n mean?

Use the function nl2br() on your output. The characters "\r\n" represent the newline character. "\r" is a carriage return and "\n" is a line-feed. On UNIX systems "\n" is the newline character. On Macs it is "\r".

 

The nl2br() function will put a "<br>" tag in front of each newline character.

\r = CR (carriage return)

\n = LF (line feed)

they are used for splitting into lines..

but to start a new line depends on the system..

Windows = \r\n

unix = \n

Mac = \r

 

Now. if you view source your see the line are broken up.. but you need to convert this to html.. so to do this

use nl2br()

ie

<?php
$str ="Hello.\r\n\r\nText goes here.\r\n\r\nAnd a seperate paragraph here also!";
echo nl2br($str);
?>

 

 

EDIT:

Ahh .. too slow

Cool guys, thanks both of you!

[Zane]

\r is a carriage return and \n is newline character

 

you really only need one or the other, but most people use both of them together as one

\r\n

to make their scripts work with as many browsers/applications as they can

 

 

 

EDIT

damn...everyone beat me
