#50503 [Com]: proc_open loses constants with $env

ID: 50503 Comment by: carsten_sttgt at gmx dot de Reported By: tidustracker at freenet dot de Status: Feedback Bug Type: Program Execution Operating System: Windows Vista PHP Version: 5.3.1 New Comment: > but that's not a proc_open bug then. Correct, but I think it there a basic problem with proc_open on Windows. In this case with the environment. Just see this example: http://de.php.net/manual/en/function.proc-open.php#function.proc-open.examples It's not working on Windows (returning 1 and no output). If you change: - $process = proc_open('php', $descriptorspec, $pipes, $cwd, $env); + $process = proc_open('php', $descriptorspec, $pipes); it's "working". But also no output, because the environment $_ENV is empty (even the new process should inherit the current ENV). if you now change: - write($pipes[0], '<?php print_r($_ENV); ?>'); + write($pipes[0], '<?php print_r($_SERVER); ?>'); you can see there is an output. But as long $env is an array (and not null) the script is not working). And so it's also not possible to define new env variables for the new process. Regards, Carsten Previous Comments: ------------------------------------------------------------------------ [2009-12-17 01:31:51] pajoye@php.net but that's not a proc_open bug then. PHP has no idea about what has called it. I'm not sure either why they are not defined in this case. ------------------------------------------------------------------------ [2009-12-17 01:22:23] tidustracker at freenet dot de The script is working very well? Adjust the two paths and run it in CLI. The ENVs are not the problem, the ENVs cause the problem. The php example code starts via proc_open a new php process. With an passed $env array to proc_open, the two constants SOL_TCP and SOL_UDP described at http://php.net/manual/en/sockets.constants.php are missing in the new php process. ------------------------------------------------------------------------ [2009-12-17 01:01:51] pajoye@php.net Please provide a valid/working script. The easiest way to verify that all ENVs are correctly defined is to simply echo them out (echo %ENVNAME%). ------------------------------------------------------------------------ [2009-12-17 00:40:37] tidustracker at freenet dot de Description: ------------ It seems that passing an array(filled or empty) to proc_open drops the two constants SOL_TCP and SOL_UDP in created process Reproduce code: --------------- $arrConstants = get_defined_constants(true); print('Constants: '. count($arrConstants['sockets']) . PHP_EOL); print_r($arrConstants['sockets']); ob_start(); ?> $arrConstants = get_defined_constants(true); file_put_contents('D:/proc_open_bug.txt', 'Constants: '. count($arrConstants['sockets']) . PHP_EOL . print_r($arrConstants['sockets'], true)); <?php $strCode = ob_get_contents(); ob_end_clean(); $arrDescriptor = array(0 => array('pipe', 'r'), 1 => array('pipe', 'w'), 2 => array('pipe', 'w')); $arrOptions = array('suppress_errors' => false, 'bypass_shell' => true); $arrPipes = array(); $strCWD = null; $arrEnv = array('process' => true); // Constants SOL_TCP and SOL_UDP are NOT available in opened process #$arrEnv = null; // All fine with constants SOL_TCP and SOL_UDP proc_open('php_53 -r "'. $strCode. '"', $arrDescriptor, $arrPipes, $strCWD, $arrEnv, $arrOptions); Expected result: ---------------- passing an array to proc_open expects 86 constants including SOL_TCP and SOL_UDP in the new process Actual result: -------------- only 84 constants ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50503&edit=1
