Further discussion on "<br/>" and "\ r \ n" What is the difference between the two? _php Tips

\ r \ n is the output of the HTML code wrapping, the customer see the effect does not wrap.
<br/> is the opposite
Effect:
I am content \ r \ n I am content
I was content <br/> I was content
==================================================
\ r means: A carriage return (acsii:13 or 0x0d), which is what we often call a hard return.
\ n says: line break (Acsii:10 or 0x0a), is what we often say soft return.

These two are not visible on the page. Right-click to view source file you can see code wrapping
==================================================
If it is output to the browser, use <br/>
If it is output to its own file, use "\ n", Windows is "\ r \ n"
==================================================
\ n, like you do a Web page in the Dreamweaver, click Enter in the source code, is to the source code line.
is the output of one (HTML markup Language), interpreted as a word-wrapping in HTML. \ n's role is to line up the source code, input, look at the HTML source code, see there will be a newline, and the HTML interpreter (browser) think it is useless things, with not all the same display.
==================================================
\ n is source code wrapping!
<br/> is the Web page performance line!!
