php Newlines vs html break

This code:

<?php
  echo "This is the first line. \n";
  echo "This is the second line.";
?>

Echoes out all on the same line: ("This is the first line. This is the second line.")

Shouldn't \n have basically the same function as <br> ? What am I missing here?

HTML doesn't render \n, a \n will put a break in your HTML source code

PHP

<?php
echo "<p>This is the first line. \n";
echo "This is the second line.</p>";
?>

HTML Source

<p> This is the first line.
This is the second line.</p>

HTML 

This is the first line. This is the second line.

PHP

<?php
echo "<p>This is the first line.";
echo "This is the second line.</p>";
?>

HTML Source

<p> This is the first line.This is the second line.</p>

HTML 

This is the first line.This is the second line.

PHP

<?php
echo "<p>This is the first line. <br/>";
echo "This is the second line.</p>";
?>

HTML Source

<p> This is the first line.<br/>This is the second line.</p>

HTML 

This is the first line. 
This is the second line.

You mix up the output of php and the result in your browser. \n is newline. You may see it, when you read the source code in your browser(Ctrl + U in Chrome) .

But browser only render <br> as newline on webpage

echo "This is the first line. \n";

Will produce a linebreak in your source, meaning the cursor is currently on the next line (the line belove the text).

echo "This is the second line.";

Will produce a single line and leave the cursor right after the text (on the same line).

echo "This is the second line.<br />";

Will produce a single line but in rendered html containing a visible linebreak. However, in the sourcecode there will be no linebreaks, so:

echo "Line one<br />Line two";

Will render two lines in html but one line in the source.

echo "This is the first line.", '<br />', PHP_EOL;

^ HTML code for BR and ENTER.
ENTER is visible in the source or PRE tags, or TEXTAREAs, or when enabled by CSS white-space (etc.) while BR is the line break in HTML.
