http://localhost/test.php?var=5
results in (global scope)
$var = 5; // Register globals on
$HTTP_GET_VARS['var'] = 5; // Always (?)
$_GET['var'] = 5; // With newer versions of PHP
To access this from a function:
function x() {
global $var;
globsl $HTTP_GET_VARS;
echo $var.'<BR>';
echo $HTTP_GET_VARS['var'].'<BR>';
echo $_GET['var'].'<BR>';
}
Note, that there is no "global $_GET;" - $_GET is a superglobal. That means,
you can always access it.
