Hi,

I tried to use pty terminal type with PHP proc_open() function but could not 
success and got following message:

PHP Warning:  proc_open(): pty pseudo terminal not supported on this system in 
xxxx.php on line xx

I saw it was raised somewhere in 2006 with Bug #39224 but not sure why it was not 
fixed. 

If you can give any clue why it was not fixed? Any security or any other issue? I 
can see this code is still available in proc_open.c


Any help will be highly appreciated.

Kind regards
Mohtashim



Test script:
---------------
$descriptorspec = array(
  0 => array("pty"),
  1 => array("pty"),
  2 => array("pty")
);

$cwd = '/tmp'; 
$env = array('some_option' => 'aeiou');

Expected result:
----------------
No error.

Actual result:
--------------
PHP Warning:  proc_open(): pty pseudo terminal not supported on this system in 
xxxx.php on line xx
