It should be noted that unset variables will still be returned by func_get_arg(), as shown below:
function allSet() {
for($i = 0, $j = func_num_args(); $i < $j; $i++) {
$thisArg = func_get_arg($i);
if(!isset($thisArg)) {
return FALSE;
}
}
return TRUE;
}
$x = 1;
$y = 0;
$z = "Four score and seven years ago...";
echo (allSet($x, $z) ? 'All' : 'Some') . " vars are set in the first
set.<br>\n";
echo (allSet($w, $x, $y, $z) ? 'All' : 'Some') . " vars are set second
set.<br>\n";
