PHP Globals?

[Newsgroup_User]

I'm looking at a script that has this line -

$GLOBALS[$key] = $val;

Am I remembering something bad about such usages? Or am I thinking of
register_globals?

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.

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

Something different.

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>";

?>
