PHP code best practices

Being new to PHP I would like how to organize my code better. I usually organize it the exact same page on every page. This are the parts I have recognized so far:

1) PHP code (example below)

<?php require_once( "../../webassist/security_assist/helper_php.php" ); ?>
<?php
if (!WA_Auth_RulePasses("Logged in to pcms2_users")){
      WA_Auth_RestrictAccess("../../logout.php");
}
?>

2) <html>  tag

3) <meta content>

4) <head>

5) <link .. to stylesheets>
6) <scrpt type ... >

7) </head>

8) <body>

9) All the 'body' code

10) </body>

11) </html>

Would that be accurate ?  or can I have the PHP code elsewhere as best practice, just looks weird to me that it is at the very top before my meta tags, etc.  I would usually have it between my meta tags and before the <head> content.

Any pointers for best practices are welcome.

You should spread it out if needed through the body, this is how you generate dynamic pages.  In the head if you need it to populate any of your in page JavaScript.  Remember if you name you called .js and .css files using a .php extension you can also dynamically alter those as well.

There is a lot more to "best practices" than just the flow of linked PHP scripts, but some of the concepts are available in this article and the linked resources.

As a general rule, I would suggest a common.php script that handles all of the standard startup stuff -- starting the session, acquiring the cookies, if any, connecting to the database and acquiring the active records indicated by the cookies.  The fewer "echo" statements you have, the more likely you will write debuggable and maintainable code.  Be sure to use the W3 validator frequently as you build out your HTML, CSS and JavaScript!
