Useful script:

<?php

// GLOBALS

echo "<pre>";
print_r ($GLOBALS);
echo "</pre>";

# OTHER PREDEFINED VARIABLES

echo "<pre>";
print_r ($_SERVER);
echo "</pre>";

echo "<pre>";
print_r ($HTTP_SERVER_VARS);
echo "</pre>";

?>

Yes, using global variables is bad style. The better ways would be OOP
or to pass the required values to the function.

Something different.

It depends how the value is originally obtained, and if it has been
sanitized and validated. In general, though, I would steer away from its
use.
