There are 5 test cases that have different results between s390x and
x86=5F64:

All are related to the new function stream=5Fisatty().
Here is a short sample php:

   # more sample.php
   <?php

          $closeMe =3D fopen(=5F=5FFILE=5F=5F, 'rb');
          $tmp=3Dstream=5Fisatty($closeMe);
          echo "closeme=3D$closeMe, stream=5Fisatty=3D$tmp+\n";
          echo "closeMe:"; var=5Fdump(stream=5Fisatty($closeMe));

on s390x, it outputs:

   #php sample.php
   closeme=3DResource id #5, stream=5Fisatty=3D1+
   closeMe:bool(true)

and on x86=5F64 it gives:

    # php sample.php
   closeme=3DResource id #5, stream=5Fisatty=3D+
   closeMe:bool(false)

Note that both platforms output $closeMe =3D"Resource id #5", however
"stream=5Fisatty($closeMe)" gives different results.
On x86=5F64 it is empty or null.   I did not find document of this function
online.
Can you tell me  which result is correct?

Thanks,
