http://php.net/include/

Quote: "When a file is included, the code it contains inherits the variable scope of the line on which the include occurs. Any variables available at that line in the calling file will be available within the called file, from that point forward. However, all functions and classes defined in the included file have the global scope."


Should tell you what you need to know.

When you include a PHP file, it literally inserts the PHP code (in the included file) at that point in your script.

For example:



If you ran that, you would see 'orange' printed out, because there is a variable called $a declared in the included PHP file, that has over-written the variable set before it.

Following this logic rather than doing:

<?php include "score.php?game=1"; ?>

You can set the 'game' variable before the included script:

$game = 1;
include 'score.php';

Then make 'score.php' check for the existence of $game.

Cheers,

Rich

You can just use <?php require_once('filename'); ?>.

Useful if you want to include files that may contain global functions, or to set configuration values.

thats a different command...

include is more of a "trier". It will try to include but wont fully die if it cant. It'll just produce an error saying it cant. Require, however, is a "do-or-die" type command. If it cant get that file then it will kill the process and the page wont load. That file is REQUIRED.

You've also tagged on the _once suffix. This does an extra check to see if you've already included the file (to avoid duplicate function names, etc). Usefull if you dont know if you've done it before or not, but shouldn't just be used all the time. It has overhead that might not always be necessary.

.. which won't work in this instance as the super globals will have never been populated via an include.
