There are 5 test cases that have different results between s390x and
x86_64:

|-----------------------------------------------------------------------------|
|Test stream_isatty with redirected STDERR |
|tests/output/stream_isatty_err.phpt.] |
|-----------------------------------------------------------------------------|
|Test stream_isatty with redirected STDIN/STDERR |
|[tests/output/stream_isatty_in-err.phpt] |
|-----------------------------------------------------------------------------|
|Test stream_isatty with redirected STDIN/STDOUT |
|[tests/output/stream_isatty_in-out.phpt] |
|-----------------------------------------------------------------------------|
|Test stream_isatty with redirected STDOUT |
|[tests/output/stream_isatty_out.phpt] |
|-----------------------------------------------------------------------------|
|Test stream_isatty with redirected STDOUT/STDERR |
|[tests/output/stream_isatty_out-err.phpt] |
|-----------------------------------------------------------------------------|

All are related to the new function stream_isatty().
Here is a short sample php:

more sample.php

<?php

      $closeMe = fopen(__FILE__, 'rb');
      $tmp=stream_isatty($closeMe);
      echo "closeme=$closeMe, stream_isatty=$tmp+\n";
      echo "closeMe:"; var_dump(stream_isatty($closeMe));

on s390x, it outputs:

#php sample.php
closeme=Resource id #5, stream_isatty=1+
closeMe:bool(true)

and on x86_64 it gives:

# php sample.php

closeme=Resource id #5, stream_isatty=+
closeMe:bool(false)

Note that both platforms output $closeMe ="Resource id #5", however
"stream_isatty($closeMe)" gives different results.
On x86_64 it is empty or null. I did not find document of this function
online.
Can you tell me which result is correct?
