New Comment:
This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.
Thank you for the report, and for helping us make our documentation
better.
Only first call of this function return real value, next calls return
-1.

This is a not a bug, but an undocumented behaviour.

Description:
------------
After a process (via proc_open()) has exited, proc_get_status() returns
the actual exit code (within array['exitcode']) of that process.
If proc_get_status() gets called a second time, the previous exit code
will be lost (-1), because the internal waitpid() function won't return
the pid a second time.
So, either this is a bug and proc_get_status() has to keep track of the
exitcode value (as it does for 'command', 'pid' and 'running') or this
behaviour should be mentioned in the documentation.
Reproduce code:
---------------
#!/usr/bin/env php
<?php
$descriptors = array(
0 => array('pipe', 'r'),
1 => array('pipe', 'w'),
2 => array('pipe', 'w'));
$pipes = array();
$ressource = proc_open('/bin/true', $descriptors, $pipes);
echo stream_get_contents($pipes[1]);
// first call exitcode == 0
var_dump(proc_get_status($ressource));
// second call exitcode == -1
var_dump(proc_get_status($ressource));
fclose($pipes[1]);
proc_close($ressource);
?>
Expected result:
----------------
array(8) {
["command"]=>
string(9) "/bin/true"
["pid"]=>
int(31590)
["running"]=>
bool(false)
["signaled"]=>
bool(false)
["stopped"]=>
bool(false)
["exitcode"]=>
int(0)
["termsig"]=>
int(0)
["stopsig"]=>
int(0)
}
array(8) {
["command"]=>
string(9) "/bin/true"
["pid"]=>
int(31590)
["running"]=>
bool(false)
["signaled"]=>
bool(false)
["stopped"]=>
bool(false)
["exitcode"]=>
int(0)
["termsig"]=>
int(0)
["stopsig"]=>
int(0)
}
Actual result:
--------------
array(8) {
["command"]=>
string(9) "/bin/true"
["pid"]=>
int(31590)
["running"]=>
bool(false)
["signaled"]=>
bool(false)
["stopped"]=>
bool(false)
["exitcode"]=>
int(0)
["termsig"]=>
int(0)
["stopsig"]=>
int(0)
}
array(8) {
["command"]=>
string(9) "/bin/true"
["pid"]=>
int(31590)
["running"]=>
bool(false)
["signaled"]=>
bool(false)
["stopped"]=>
bool(false)
["exitcode"]=>
int(-1)
["termsig"]=>
int(0)
["stopsig"]=>
int(0)
}
