Can't find the code on a "view source" on the index.php

[flashawd]

Hello - I am new to the forum and also PHP - I was on www.w3schools.com - learning the basics. My issue is when I do a "view source" of an index.php page in a browser I am able to see all the coding on that page (html and css), and also see where I need to modify some text. When I download this page "index.php" from the server - it is not what I am seeing in the "view source" - it is strictly a "<?php...?> with only PHP code on the page. I searched the forum to try to find the answer, but kind of hard to work the problem, so nothing really came up. Thanks for any help for this PHP newbie. Thank you for any help.

Thanks - Eric

Yep, that's normal behaviour.
PHP code is pre-processed on the server, and the results are sent to the client. The client then interprets it. Typically, this is used in a web environment, so PHP generates the dynamic content and sends the results in HTML:

PHP Code:

<?php

if (date("a") == "pm")
{
    $sPartOfDay = "evening";
}
else
{
    $sPartOfDay = "morning";
}

printf('<p>good %s</p>', $sPartOfDay);
?>

Would be the PHP code, and what the browser sees is:

<p>good afternoon</p>

or good morning if its 'am'. So what you see in the browser is only what is printed or echo'd to the browser, or anything outside of <?php and ?> tags.

Thank you very much for your quick reply. Great explanation, that was kind of my understanding when I was on w3schools.com. In this case is it calling on another file - that I need to look at? (see below) I basically just need to change the copyright date and phone numbers on the front of the site. ;-) This is what is on the index.php that I am working with. Thanks again, pretty interesting stuff - will be fun to really get into it.

<?php
// SESSION START/CONTINUE
@ session_start();

// SECURITY/CONFIG
define('IN_MAIN',true);
$path_site = './';
$page = 'index';

// INCLUDES
require_once($path_site.'inc/database.php');
require_once($path_site.'inc/constants.php');
require_once($path_site.'inc/common.php');

// LOGIC \\
if(isset($_SESSION['user']['id'])) { redirect($path_site.'networks.php'); exit(); }

$CONTENT = replace_output( file_get_contents(PATH_CB.'home'.EXT_CB), array(
'path_site'=>$path_site
));

// OUTPUT \\
$OUTPUT = replace_output( file_get_contents(PATH_TPL.'main'.EXT_TPL), array(
'path_site'=>$path_site,
'sbu'=>SITE_BASEURL,
'meta_kw'=>SITE_KEYWORDS,
'meta_desc'=>SITE_DESC,
'meta_title'=>SITE_TITLE,
'nav_list'=>get_nav_list(),
'content'=>$CONTENT
));
print($OUTPUT);

?>

Yep, this is using a framework of some type.
Check in the constants.php and common.php files for settings. There may be a config file elsewhere for it as well.
