php string questions

[jimdy]

Here is a simple code
<?php

echo "hello \n world";
?>

when I load the page(apache 1.3.27) on the internet explorer it shows:

hello world

but when I check the source it shows the correct output which is:

hello
world

anyone know why?

thank you

to make it look like this:

hello
world

then you must do like this:

<?php

echo "Hello<br>\nWorld";

?>

thank you it works I forgot to use html tags
but why does \n has no effect?

because the following code also works the same:

<?php
echo "hello <br> world"
?>

because the following code also works the same:

That's not true. \n is a new line, equivalent to pushing enter in your browser. Look at the following code

this 
        is 


html                             


                      code

You know what HTML processes that as in your browser?

this is html code

Why? There are no <br> tags. I can hit enter and space as many times as I want; spaces mean nothing in HTML. It helps you organize your code. Essentially, what \n does is the same as pushing enter.

echo "<tr>\n<td width=200>\ncode\n</td>\n</tr>\n";

will print in html as

<tr>
<td width=200>
code
</td>
</tr>

If you want a line break, which is completely different, in html you wouldn't write

hello
world

to have it print that way. You would write

hello<br>world

Hope this clears up any confusion.

Thank you for your reply but I am not sure if you answered my originial question.

Here is some php code I tried :
<?php
echo "hello \n world";

echo "hello
world";
?>

The outout I got on internet explorer is: hello world
Aren't they suppose to output

hello
world

???

I figured it out now, but whats the function of \n in php anyways? Is it only used to organize the code?

When you write to files, it's very useful. In HTML, you'll write "<BR />", but in file, HTML code is normally unuseful. So you put a "enter" by writing "\n".

\n is also helpful when setting up a message for your email. In that case youw ouldn't use <br>, you'd use \n

$msg = "Dear Bob,\n\n";
$msg .= "I'm going to start a new line now.\n";
$msg .= "Thanks for reading my email.\n\n";
$msg .= "Cgraz";

If mailed would output

Dear Bob,

I'm going to start a new line now.
Thanks for reading my email.
