I have a text box, and I would like to add in a carriage return in the box when inputting data through a php script, so that when the information is seen on the website, it would be formatted thus. Can anyone point me in the direction of a script that would help to make this possible?

$text = "line one\r\nline two\r\nline three\r\n";
<textarea><?php echo $text; ?></textarea>
carriage return is accomplished by using "\r" (must be inside double quotes)
new line is accomplished by using "\n" (must be inside double quotes)
macs use \r for a "new line", *nix use \n, win uses \r\n
you should use \r\n, that way you know its always gonna work

probably [php_man]nl2br[/php_man] is an interesting function

OK I think I sort of understand. Does this mean that on the webform that I type into, that if I were to type in: "This restaurant is great. \r We love to eat here."
That it would return this:
This restaurant is great.
We love to eat here.
Thanks again.

yes, but ONLY if you have have php echo it
when php encounters a \r inside of a double quotted string, it will change \r into a carriage return
try the little code bit i posted
again, id recomend using \r\n, because if the browser doesnt interpret a lone \r or \n correctly, visually to the user it will look like its all on 1 line.
if you use \r\n then all browsers will definately render it correct.
theres prob few browsers that wouldnt interpret a lone \r or \n correctly, but i dont see any real drabacks to being safe about it.

depending on the browser, and if the html has specified a certain wrap="virtual" attribute or whatever, yes. (default most browsers definately insert temporary, line breaks)
but when they submit the form, the virtual line breaks wont be sent. but depending on the wrap="" it could be. theres diff ways you can choose as the html designer.
i hope i have confused you
