here is a "server-php >> html >> browser" process illustration:

it shows the basic steps; first php code is parsed at server into html; then sent to browser, that understands html tags and renders them to the display the webpage, there's also some quick overview about the process.. worths taking a look at

before html runs to show a webpage, php code runs first on web server.



so, when there lines as follow:



<table>

<tr>

<td>

  <?php

    echo "php runs first!";

  ?>

</td>

</tr>

</table>



the first step is to run php code, we get:



<table>

<tr>

<td>

php runs first

</td>

</tr>

</table>



then, code is sent to browser, and we see somthing~

"the code is executed on the server"





This is an important concept for the first-time PHP programmer to understand, so that when you get into string formatting later on, you understand the difference between formatting the on-screen content (as parsed by your browser) and formatting the HTML code (as returned by the server).


For example "\n" starts a new line in the HTML code, and its results are only seen if you look at the "source HTML". It is NOT the same as <br>!
