What is the "\n"

[Anon]

Hello, I have a simple question today. I looked in the php manual for this answer, but could not find it. What does the "\n" do when using the echo or print command? It seems all scripts have this when using echo. Thanks for the help

\n is like if you wrote enter after a line...

Ex :
echo "one";
echo "two";

Will produce : "onetwo"

echo "one\n";
echo "two";

Will produce : "one
two"

Thanks. So it just like a <br> tag too. I just could not find that anywhere. Thanks for the help.

That's not realyythe way it works, I think.

It's not used to replace the <br /> (or <br>) tag. It does end a line, but not in your browserwindow, but in your view source window. So when you use a \n after each html-tag you use in your scripts, or after each line, you're html-output wil be displayed over more than just one line.

"\n" is the equivalent of pressing the enter key on your keyboard. So, if you are writing to a file with the code:

$line1 = "This is line 1";
$line2 = "This is line 2";
fwrite ($whatever, $line1 . "\n" . $line2);

the file would look like this:

This is line 1
This is line 2

it would not look like this:

This is line 1<br>This is line 2

or:

This is line 1\nThis is line 2
