$x = isSet($x) ? "Set" : "Not Set";
$y["x"] = isSet($y["x"]) ? "Set" : "Not Set";
if (isSet($z["x"]))
  $z["x"] = "Set";
  $z["x"] = "Not Set";

print "x = " . $x . "<BR>\n";
print "y[\"x\"] = " . $y["x"] . "<BR>\n";
print "z[\"x\"] = " . $z["x"] . "<BR>\n";

$x gets set to "Not Set" - Correct
$y["x"] gets set to "Set" - Not Correct
$y["x"] gets set to "Not Set" - Correct

This problem does not happen in 4.0b2 only in 3.0.12 (and I suppose other versions of php3.0.x)

The variables is question have never been used before, as can be seen.

The problem may be in
$y["x"] = isSet($y["x"]) ? "Set" : "Not Set";

Maybe there is some kind of "look behind" being done?
This looks like a fun one! :)
