Hello,

Pseudoterminals (aka PTY) are very useful in many cases (please, read [1] [2] [3]). PHP has a “disabled” implementation of PTY (please see discussion [4] and you will find relevant links inside).

I wonder if technical issues encountered in the past are always true nowadays. If it does not, it would be a very great enhancement!

Test script:
---------------
<?php

$p = proc_open(
    'php',
    [0 => ['pty', 'r'], 1 => ['pty', 'w']],
    $pipes
);

Actual result:
--------------
Warning: proc_open(): pty pseudo terminal not supported on this system in /tmp/foo.php on line 7
