For the initial comment and other: <?php echo PHP_EOL; error_reporting(E_ALL|E_NOTICE); $cmd = '"c:\\Program Files (x86)\\wcat\\wcutil.exe"'; $des = array ( 0 => array('pipe', 'r'), 1 => array('pipe', 'w'), 2 => array('pipe', 'w') ); $resource = proc_open($cmd, $des, $pipes, null, $_ENV); var_dump(stream_get_contents($pipes[0])); var_dump(stream_get_contents($pipes[1])); var_dump(stream_get_contents($pipes[2])); echo PHP_EOL; echo "exec: " . PHP_EOL; echo exec($cmd, $ret); echo PHP_EOL; print_r($ret); echo PHP_EOL; gives me: string(0) "" string(441) "Usage: wcutil [-s] [-d] [-x] [filename(*)] -s(imple) Do not display CSV headers or average. -x(ml) Xml output. -d(rophighlow) Drop highest and lowest path runs.

Using 5.3.5 and 5.3-svn or trunk, on Windows 7/2003/2008. Please try again and let me know if it still fails, using this exact sample (can be other command), or repost an example to reproduce it. I will also need to know which windows version you use.

We have issue in our project based on this bug. I assume second call in the example should work.. Related issue: https://issues.apache.org/jira/browse/ZETACOMP-48 Thanks. ------------------------------------------------------------------------ [2010-04-23 08:46:52] David dot Gausmann at measx dot com This is the same problem as mine: $Command = '""c:\program files\doxygen\bin\doxygen.exe" "C:\fred\doxyfile""'; $DescriptorSpecification = array ( 0 => array('pipe', 'r'), 1 => array('pipe', 'w'), 2 => array('pipe', 'w') ); $Resource = proc_open($Command, $DescriptorSpecification, $Pipes, null, $_ENV); Works fine (because it has the nasty double quotes around everything). ------------------------------------------------------------------------ [2010-04-23 02:22:47] xandrani at googlemail dot com The double backward slashes didn't show correctly... but they are in my code. ------------------------------------------------------------------------ [2010-04-23 02:20:33] xandrani at googlemail dot com Something similar fails for me... but even worse! $Command = '"c:\program files\doxygen\bin\doxygen.exe" "C:\fred\doxyfile"' $DescriptorSpecification = array ( 0 => array('pipe', 'r'), 1 => array('pipe', 'w'), 2 => array('pipe', 'w') ); $Resource = proc_open($Command, $DescriptorSpecification, $Pipes, null, $_ENV); I get the error: 'c:\program' is not recognized as an internal or external command, operable program or batch file. This works on exec() so not sure what's going on. ------------------------------------------------------------------------ [2009-08-03 13:09:56] david dot gausmann at measx dot com Description: ------------ The command, which shall be executed via proc_open, must be put in double quotes. This bug was on functions like system, exec, ... It seems not to be fixed on proc_open. Reproduce code: --------------- --- script1.php --- <?php //Works fine echo "1.\r\n"; system('"C:\php\php.exe" "C:\php\script2.php"'); //FAILS! echo "2.\r\n"; $arPipes = array(); $rProcess = proc_open('"C:\php\php.exe" "C:\php\script2.php"', array(array('pipe', 'r'), array('pipe', 'w'), array('pipe', 'w')), $arPipes); if($rProcess !== false) { $nExitCode = -1; do { while(!feof($arPipes[1])) { echo fread($arPipes[1], 1024); flush(); } $array = proc_get_status($rProcess); if(!$array) break; } while($array['running']); fclose($arPipes[0]); fclose($arPipes[1]); fclose($arPipes[2]); proc_close($rProcess); } //Works fine (double quotes added) echo "3.\r\n"; $arPipes = array(); $rProcess = proc_open('""C:\php\php.exe" "C:\php\script2.php""', array(array('pipe', 'r'), array('pipe', 'w'), array('pipe', 'w')), $arPipes); if($rProcess !== false) { $nExitCode = -1; do { while(!feof($arPipes[1])) { echo fread($arPipes[1], 1024); flush(); } $array = proc_get_status($rProcess); if(!$array) break; } while($array['running']); fclose($arPipes[0]); fclose($arPipes[1]); fclose($arPipes[2]); proc_close($rProcess); } ?> ---script2.php--- <?php echo "Lorem ipsum\r\n"; exit(0); ?> Expected result: ---------------- 1. Lorem ipsum 2. Lorem ipsum 3. The third call of proc_open should fail, the second one should work. Actual result: -------------- 1. Lorem ipsum 2. 3. Lorem ipsum The second call of proc_open should fails, but the third one works. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=49139&edit=1
