'"c:\program files\doxygen\bin\doxygen.exe" "C:\fred\doxyfile"'
works fine with proc_open.
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.
Column details:
file - output filename
tps - transactions per second
kcpt - kilocycles per transaction (aka 'path')
bpt - bytes per transaction
cpu - percent CPU utilization
err - count of any errors
"
string(0) ""
exec:
Array
(
[0] => Usage: wcutil [-s] [-d] [-x] [filename(*)]
[1] => -s(imple) Do not display CSV headers or average.
[2] => -x(ml) Xml output.
[3] => -d(rophighlow) Drop highest and lowest path runs.
[4] =>
[5] => Column details:
[6] => file - output filename
[7] => tps - transactions per second
[8] => kcpt - kilocycles per transaction (aka 'path')
[9] => bpt - bytes per transaction
[10] => cpu - percent CPU utilization
[11] => err - count of any errors
[12] =>
)
which is correct.
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.

Can someone speed up the fix? 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.

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).

The double backward slashes didn't show correctly... but they are in my
code.

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.

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.
