Sorry, but the bug system is not the appropriate forum for asking
support questions. Your problem does not imply a bug in PHP itself.
For a list of more appropriate places to ask for help using PHP,
please visit http://www.php.net/support.php

Thank you for your interest in PHP.

the "variable variables" feature works on plain variable names only, there is no array resolving done

$$t is equal to $GLOBALS[$t] here
and    $GLOBALS["extractid[$i]"] 
is not $GLOBALS["extractid"][$i]
