[Resolved] How come \n does not work in my scripts?

stenk

Hi all,

Not sure why I can not get \n to create a new line

For example:

array.php

<?php
$colors = array('red', 'blue', 'green', 'yellow');

foreach ($colors as $color) {
   echo "Do you like $color?\n";
}

?>

Outputs this:

Do you like red? Do you like blue? Do you like green? Do you like yellow?

This is what it is supposed to output:

Do you like red?
Do you like blue?
Do you like green?
Do you like yellow?

But if I use the HTML tag it works fine.

Webserver is Apache
PHP5.0

Kind regards,

Just wondering, but why not just use the tag if it works? =)

Thats not at issue here. I need to know why the "\n" tag does not. I am sure there are instances where I will need to use "\n" other then the tag.

When the text is output it is interpereted by the browser which reads html. is an html tag, not /n. So it's not really a php thing, it's a browser/html thing.

Thanks gufmn,

Still does not explain it for me. I dont have an issue with HTML tags, just do not understand why \n does not create a new line.

you could try /r/n, which is what i need to do on my windows system. but like gufmn said, /n won't ever work in a browser...as a browser doesn't understand what /n or /r/n means.

Maybe this will help. Create a new file and call it something like newline.htm. In it have something like:

Do not use any php tags.
See what it looks like in your browser.

This doesn't mean you won't ever have to use \n. For instance, when sending mail through the mail() function, you might want to alter the header to send a CC to someone, in which case you'd use \r\n. But that is because it needs to be that way for the mail server to read it correctly. In the same manner, you need to use a in order for the browser to read it correcty.

Hope this helps.

Thanks Gufmn and whoisKeel,

I think I understand now.

Thanks for your time.

Regards to you both.
