You can see the below code in action at:
http://www.ionzoft.com/code/testing/globals.php
<?
function CreateGlobals($td)
{
$td = "foo";
$td_error = $td . "_error";
$td_ok = $td . "_ok";
global $$td_error;
global $$td_ok;
$$td_error = 'Error Message';
$$td_ok = 'Ok Message';
}
////////////////////////////////////////////////////////////////////
//Just testing
echo 'Before Call to CreateGlobals()<br>';
echo '$foo_error = ', $foo_error, '<br>';
echo '$foo_ok = ', $foo_ok, '<br>';
echo '<br>';
CreateGlobals("foo");
echo '<br>';
echo 'After Call to CreateGlobals()<br>';
echo '$foo_error = ', $foo_error, '<br>';
echo '$foo_ok = ', $foo_ok, '<br>';
?>
There is probably a better way to do this.
Check the docs on Variable Variables and the {} syntax.
