Hello,
with the code below, $rv is 0 :-)

--- begin code --- $pdesc=[0=>['pipe','r'],1=>['file','stdout.log','w'],2=>['file','stderr.log','w']];
$proc=proc_open('sleep 3',$pdesc,$pipes);
fclose($pipes[0]);
$rv=proc_close($proc);
echo('rv: '.$rv.PHP_EOL);
exit(0);
--- end code ---

With the code below, $rv is -1 :-(

--- begin code --- $pdesc=[0=>['pipe','r'],1=>['file','stdout.log','w'],2=>['file',stderr.log','w']];
$proc=proc_open('sleep 3',$pdesc,$pipes);
$done=false;
while ($done===false) {
$pstat=proc_get_status($proc);
if (!$pstat['running']) $done=true;
usleep(500000);
}
fclose($pipes[0]);
$rv=proc_close($proc);
echo('rv: '.$rv.PHP_EOL);
exit(0);
--- end code ---

Why oh why?

When I read:

last comment in https://www.php.net/manual/en/function.proc-close.php

second comment in https://www.php.net/manual/en/function.proc-get-status.php

then one could get the idea that proc_get_status take the status
code for $pstat['exitcode'] and proc_close after that return -1.

I guess it's as Arne already pointed out the second comment on proc_get_status() that has deciphered the "The exit code returned by the process (which is only meaningful if running is false). Only first call
of this function return real value, next calls return -1."
So as long as you don't try to get the status you will get it when you
run proc_close, if you use proc_get_status you will need to keep track
of the status code yourself by storing in a variable that you can access
when you execute proc_close, here is a simple fix where we have the
latest $pstat with the correct exit code:

--- start of file --- $pdesc=[0=>['pipe','r'],1=>['file','stdout.log','w'],2=>['file','stderr.log','w']];
$proc=proc_open('sleep 3',$pdesc,$pipes);

do {
$pstat=proc_get_status($proc);
usleep(500000);
} while($pstat['running']);

fclose($pipes[0]);
$rv=proc_close($proc);
echo('rv: '.$rv.', exit code: '.$pstat['exitcode'].PHP_EOL);
--- eof ---

Keep in mind that if you have another "$pstat=proc_get_status($proc);"
any where between the end of the do-while loop and proc_close, then the $pstat['exitcode'] would be -1 too.

--- begin code --- $pdesc=[0=>['pipe','r'],1=>['file','stdout.log','w'],2=>['file','stderr.log','w']];
$proc=proc_open('sleep 3',$pdesc,$pipes);

[...]

Do not trust the proc-Functions in PHP to get any process results. The
did not work reliable for this in PHP 7.4 and in 8.0/8.1 I never got any
useful result from proc_close().

If you really need to be sure to get the return code of the command you
called, wrap the call in a shell command and use the result from the
wrapper, like this:

<?php
$command = 'some-command-to-execute';

$descriptors = [
0 => ['pipe', 'r'], // stdin
1 => ['pipe', 'w'], // stdout
2 => ['pipe', 'w'], // stderr
3 => ['pipe', 'w'], // file descriptor for exit code
];
$process = proc_open($command.'; echo $? >&3', $descriptors, $pipes);
if (is_resource($process)) {
while ($output = fgets($pipes[1])) {
$shellOutput .= $output;
}
}
if (!feof($pipes[3])) {
$shellResult = (int) rtrim(fgets($pipes[3], 5), "\n");
}
fclose($pipes[3]);
proc_close($process);

// $shellOutput will contain the output of stdout
// $shellResult will not contain the return code
