what the "\n" means?

[co.ador]

It means a new line, that means that after the  "\n" a new line is going to start the parser will go down? it's like a <br/> tag kind right?

[Irap]

<br /> is a HTML, which will make things you can see in the page start a new line.

 

 

However if the text isn't formatted (and is a plain text file or the source of the HTML file) \n will start a new line with no characters visible.

 

so:

 

echo "<b>Test</b>\n<i>Hello!</i>"

 

Would print out:

 

Testhello

 

But the source of the file, would print:

 

<b>Test</b>
<i>Hello!</i>

 

Wheras:

 

echo "<b>Test</b><br /><i>Hello!</i>"

 

Would print:

 

Test

Hello!

 

But the source code would be:

 

<b>Test</b><br /><i>Hello!</i>

[co.ador]

So it means a new line in source but no in the browser display.

 

I see a lots of codes using this "\n" but really still battling for the real usage and meaning I understood some of what you said but can't related to a real live usage.

If you want an actual carriage return in the output, you use a "\n".

 

Try writing a PHP console program that has to fit its output in a display 80 characters wide.
