Question

I have a bunch of database addresses and other random long strings that I must input into functions again and again all over my site. Is there a way to make a ton of permanent, global variables in PHP that will be valid on any file on the current PHP installation?

Or should I just make a vars.php with all of the variables defined, and always include that file?

Answer 1

Create your file with the settings you need. Something like this:

<?php
    // My file name might be config.php
    $config = array(
        'db.connection' => 'localhost:3306'
        // etc...
    );
?>

Then include it into each page/file that needs it.

<?php
    require("path-to/config.php");

    // Other stuff this file does/needs
?>
