\n?

ComputerNerd888

Hi,

I am learning PHP from a book called PHP/MySQL Programming for the absolute beginner and I am reading the for loop part right now. But what I don't and the book dose not say or I missed it is what the \n is for. like:

for ($i = 0; $i < 10; $i++) {

Print "$i <br>\n";

} // end for loop

Also I guess I missed it but I though the // was to comment something but that would not make sense because than // end if would be comment and the end if would not work.

Thanks,
Andrew

I sound like a moron I think...

//

is for comment right? The book has that on all of it to just tell me that is what it is doing.

right?

Yes, the // is a comment tag. What it's doing is simply just telling you that the } is the end of the for loop. It has absolutely nothing to do with the code.

\n is a line break.

so... "Hello You,\nThis is a test\n\nBest Wishes,\nMe"

would print out like:

Hello You,
This is a test

Best Wishes,
Me

so why would he put <br>\n? and he has that in the example he has that but only skips one line.

Thanks,

<br>\n would make a line break in the actual html code.

If your entire PHP sciript is devoid of \n, the entire HTML code will be on one line.

For an example, go to www.allmovie.com, do a search and click on one of the results. View the source of that result, and you will see all their HTML is on the first line.

Placing \n and \t in your code has no effect on what the user sees on the webpage, but makes your source code more readable.

echo "</td></tr></table>";
echo "</body></html>;

will look like
</td></tr></table></body></html> in your HTML source.

but

echo "</td></tr></table>\n";
echo "</body></html>;

will return

</td></tr></table>
</body></html>

in your source code.

OK so \n is not necessary

Not functionally necessary... :rolleyes:

However, if you leave it out, I'll puke if I have to read your HTML...
