Bug description:  cannot use isset or other on variables indexed by a numerical string

Description:
------------
When dealing with arrays indexed by a numerical string (i.e. $array['1'])
and then attempting to use isset or similar on the value, results are not
as expected.

As you can see from the example below, it would be impossible to use
something such as:

$opts = getopt("1:2:a:b:");
if (isset($opts['1'])) {
  do_something();
}
if (isset($opts['2'])) {
  do_something_else();
}
if (isset($opts['a'])) {
  echo "works\n";
}
...
...

Reproduce code:
---------------
<?

// test.php

$opts = getopt("1:2:3:4:a:");
if (isset($opts['1'])) {
        echo "it worked for 1!\n";
}
if (isset($opts['a'])) {
        echo "it worked for a!\n";
}
var_dump ($opts);
?>

(host)# php -q test.php -1 hi -a bye

Expected result:
----------------
EXPECTED:
-----------
it worked for 1!
it worked for a!
array(2) {
  ["1"]=>
  string(2) "hi"
  ["a"]=>
  string(3) "bye"
}


Actual result:
--------------
ACTUAL:
-----------
it worked for a!
array(2) {
  ["1"]=>
  string(2) "hi"
  ["a"]=>
  string(3) "bye"
}
