Description:
------------
This affects php 7.0.28 that is default packages with ubuntu, could not find it in the list

seems that it will not parse more options if you have parsed one.

it has similarity with:
https://bugs.php.net/bug.php?id=35594

Test script:
---------------
create file called test.php and add:

<?php
    $fromOpt = getopt("f:");
    $toOpt = getopt("t:");

    print_r($fromOpt);
    print_r($toOpt);

?>
https://bugs.php.net/bug.php?id=35594&edit=1

then run: 
php test.php -f -t





Expected result:
----------------
Array
(
    [f] =>
)
Array
(
    [t] =>
)

Actual result:
--------------
Array
(
    [f] =>
)
Array

Firstly, active suport support for PHP 7.0 ended five months
ago[1], so this branch will only receive security related fixes.

Secondly, the expected result is actually:

  Array
  (
      [f] => -t
  )
  Array
  (
  )

See <http://php.net/manual/en/function.getopt.php>.

If you really get the reported actual result with an actively
supported PHP version, this would be a bug.  Please check again.

Well then I know, as this worked before we upgraded to 7.0, strange that existing functionality was removed then

From what I can tell, no functionality has been removed. At least,
I get the same result with PHP 5.6.32, for instance.  And this
result is to be expected, since f: looks for an option with a
required argument (which is -t in this case), and t: looks for an
option with a required argument which is not there.  Compare that
to:

  php test.php -ffoo -tbar

  =>

  Array
  (
      [f] => foo
      [t] => bar
  )
  Array
  (
      [t] => bar
 )

Which is also expected behavior.


So again, do you get differing results?

Ah yes, now I see that I did wrong, it was that there should be no space between arguments -f and -t and their values for it work as you pointed out.

-ffoo -tbar
  Array
  (
      [f] => foo
  )
  Array
  (
      [t] => bar
 )

-ffoo -t bar (this works)
  Array
  (
      [f] => foo
  )
  Array
  (
      [t] => bar
 )

-f foo -tbar
Array
(
    [f] => foo
)

Array
(
)


-f foo -t bar
Array
(
    [f] => foo
)

Array

The last two examples also behave as expected, since -f is no
valid option for getopt('t:'), so “foo” is not regarded as
argument of the -f option, but rather as non-option, which
terminates further processing of options.
