how to set variables in a php include file?

I have a set of variables that are set outside the target php include file, how would i set them in the target php include file. Example:

<?php
  $fname = "david";
?>

Now how would I set $fname in another php file?

The PHP docs have an article about variable scopes.

The global variable scope is shared across all included and required files. In your example, once you've defined $fname globally, all other PHP lines executed afterwards can access $fname even if they're in different files.

Example: if a.php is:

<?php
  $fname = "david";
?>

and b.php is:

<?php
  $fname = "sarah";
  include 'a.php';
  // $fname is now "david"
?>

then executing b.php would define $fname as "sarah", then redefine it as "david" (through a.php).

Just use it directly.

$fname = "your value";

In your other PHP file you would do:

<?php
  $fname = "david";
?>

This answers your question directly, but I would hazard a guess that you actually want to have access to variables that are set in a file that is included into your current file or something along those lines.

So

File1.php:

<?php
  $fname = "david";
?>

File2.php

<?php
require_once 'File1.php';
echo $fname;

Would result in david being printed to screen.
