For some strange reason, inserting `echo "\n";` and other scape sequence characters are not working for me, that's why I am just using `<br />` instead. 

The images of the results of examples in books and other documentations seems just alright. I'm currently using XAMPP and already used WAMPP with the same actual result. Why is that? 

**Edit:**

It seems that I cannot understand the concept after comparing your answers with this:
[PHP Linefeeds (\n) Not Working](https://stackoverflow.com/questions/3016034/php-linefeeds-n-not-working)

Edit:

Sorry I didn't realized that the link above is referring to a php code writing to a file. I just wonder why I have these few php sample programs that uses \n even though it outputs in a webpage. Thanks everyone.
