Yes when we do a pcntl_fork or a fork in C the FD must stay open but
here it's a complety new program that is started.
Proc_open use fork for starting the new process but don't cleanup open
descriptor after the fork.

IMHO, I think this is expected. When you fork under unix the open file
descriptors will be copied to the child process. proc_open just
enforces what the specified fd should look like.

Description:
------------
When executing a program with proc_open the child process that is
started by proc_open have all fd's that was opened in the master script
ex: file, database connection ....
The child process must don't have any fd open expect the fd specified
by $descriptorspec.
Reproduce code:
---------------
<?
$fd = fopen("/tmp/test.log", "w");
$descriptorspec = array(
0 => array("pipe", "r"),
1 => array("pipe", "w"),
2 => array("pipe", "w")
);
$pipes = null;
$process = proc_open("ls /proc/self/fd -l", $descriptorspec, $pipes);
while ( ( $line = fgets($pipes[1]) ) ) {
echo $line;
}
proc_close( $process );
fclose($fd );
?>
Expected result:
----------------
total 5
lr-x------ 1 root root 64 2006-06-07 12:44 0 -> pipe:[22573]
l-wx------ 1 root root 64 2006-06-07 12:44 1 -> pipe:[22574]
l-wx------ 1 root root 64 2006-06-07 12:44 2 -> pipe:[22575]
lr-x------ 1 root root 64 2006-06-07 12:44 3 -> /proc/19964/fd
Actual result:
--------------
total 5
lr-x------ 1 root root 64 2006-06-07 12:44 0 -> pipe:[22573]
l-wx------ 1 root root 64 2006-06-07 12:44 1 -> pipe:[22574]
l-wx------ 1 root root 64 2006-06-07 12:44 2 -> pipe:[22575]
l-wx------ 1 root root 64 2006-06-07 12:44 3 -> /tmp/test.log
lr-x------ 1 root root 64 2006-06-07 12:44 4 -> /proc/19964/fd
