[Using White Space]

Ohh!  Thanks for the clarification.  So it is used for ease of viewing the source code, rather than the public rendering.  Makes sense.

[Using White Space]

On page 23, there is a section in grey on using white space.  The example shown is this:

print "Line 1\nLine2"; 

I tested this and it returns simply

 

Line 1 Line 2

 

I looked in the PHP manual and found that I can use \n in the nl2br function. I tried it using this code:

print nl2br("Line 1\nLine 2"); 

And that worked, outputting this:

 

Line 1

Line 2

 

Is this an error in the book, or am I missing something.  I checked the errata and found nothing.  

 

Clearly I found one way (maybe the only way?), but I am wondering if I am missing something about how it is explained in chapter 1?
