Php echo html. Use newline, \n, or not?

Is there any difference on this:

echo "</body>\n</html>";

and 

echo "</body></html>";

I wonder if the 'newline' has any affect on browser.

There is no difference in your case. However, newline leads to anonymous text block insertion in case it is between two inline (or inline-block) elements:

<h2>Newline</h2>
<p>
<span>first</span>
<span>second</span>
</p>
<h2>No newline</h2>
<p>
  <span>first</span><span>second</span>
</p>
<h2>newline in comment</h2>
<p>
  <span>first</span><!--
  --><span>second</span>
</p>

There're some techniques to avoid these blocks, like inserting comments or setting font-size: 0 for container element.

Lotta details might be found in the article.

Yes, \n does have effect on the output of your HTML. As you can see Here.

echo "</body>\n</html>";

outputs your HTML as:

</body>
</html>

while

echo "</body></html>";

outputs your HTML as 

</body></html>

The 

 echo "</body>\n</html>";

have no echo in browser but you can see th effect in source code (the \n is not an html element and is not processed by browser 

so you can see an effect in the code generated  page (crtl+U)  as  

 </body>
 </html>

if you need an effect in browser you should use a proper tag as <br /> 

  echo "</body><br /></html>";  // in this case poorly useful do the fact add a new line between a not (normally useful part

The "\n" doesn't have any effect on the displayed html on the browser. If you want to go to the next line, echo a <br>
