\n does apparently not work

Hello,

When I write this (inside php tags off course)...

echo "Hello, World\n" ;
echo "Hello, Giannis\n" ;

I get this result...
Hello, WorldHello, Giannis

I would expect...
Hello, World
Hello, Giannis

It seems that my escape char for new line (\n) is not working properly? Something wrong with "rpidPHP" or my coding???

Hi,

I don't know much about PHP, but is it's the same as ASP that is what I'd kind of expect to see.

I would try:

echo "Hello, World " ;
echo "Hello, Giannis " ;

Browsers will treat new lines in HTML code as spaces rather than what you'd expect.

Thank you Mickey - it works!
But all the same it's strange that \n does not work - according to my books about PHP it aught to!

Hi

\n is a newline but just for the browser. Serves to format your generated code (ie. View source)

 is to really break line in the final display

I defined a NL= " \n" to have both at the same time

When you echo \n in PHP it does create a newline.

If the echo was going to a text file for example, you would see it no problem.

When the PHP is outputting to a browser the newline is still there, and can be seen if you view source, but it will show as a space on the page in your browser as newlines are not rendered in HTML, so you have to use the html code for a newline which is  

As a quick example create an HTML file with this code:

Code: Select all

<html>
<body>
1
2
3
</body>
</html>

Now even though you have a newline between the 1, 2 & 3 in the code, when viewed in your browser you will see 1 2 3 all on one line with spaces in between.

To get each number onto a new line you need to do:

Code: Select all

<html>
<body>
1<br>
2<br>
3<br>
</body>
</html>

or even

Code: Select all

<html>
<body>
1<br>2<br>3<br>
</body>
</html>

Thanks for good answers!
BTW - in which way can I see the PHP generated HTML source in rapid PHP?

Try using \r\n (carriage return plus newline). It works for me.

RapidPHP has it's own built in webserver, but you'll need to install PHP:

That will still show as a space in the rendered HTML rather than an actual line break.

The above sample code I posted I tested on our Windows server which uses \r\n for and will still show a space in the browser.
