[PHP-DEV] function stream_isatty

[Sam Ding]

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

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?
