Consider this environment:

$ cat .htaccess
AddType application/x-httpd-php .php .html
SetEnv Foo Bar

$ cat test.php
<?php
echo "Hello: ";
echo $_SERVER['Foo'];
echo $_ENV['Foo'];
echo getenv('Foo');
?>

$ cat test.html
<?php
echo "Hello: ";
echo $_SERVER['Foo'];
echo $_ENV['Foo'];
echo getenv('Foo');
?>

This is the output of test.php:

Hello BarBarBar

This is the output of test.html:

Hello 

Why might that be? How might I fix it?

If anyone knows where I can host a real webpage instead of just the HTML for one, please let me know and I'll move the content to there. Thanks.
