Bug description: proc_open is using a wrong initial working dir
Description:
------------
Hello,
each program execution function:
- exec()
- passthru()
- shell_exec()
- system()
- backtick operator
or popen() is using the current script (working) directory as working
directory for the command which is executed.
Only proc_open() is using a different directory:
- for apache2handler it the Apache ServerRoot
- for CGI it's the php-cgi.exe directory
- for FastCGI (mod_fgcid) it's also the php-cgi.exe directory
On *nix (mod_fcgid) the proc_open() working directory is as expected also
the script (working) directory.
Regards,
Carsten
Reproduce code:
---------------
<?php
header('Content-Type: text/plain');
echo "------getcwd()---------\n";
echo getcwd()."\n\n";
echo "\n\n-------popen()---------\n";
if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
$cmd = 'dir';
} else {
$cmd = 'ls';
}
$process = popen($cmd, 'r');
while (!feof($process)) {
echo fread($process, 80);
}
pclose($process);
echo "\n\n-------passthru()------\n";
passthru($cmd);
echo "\n\n------proc_open()------\n";
$descriptorspec = array(
0 => array('pipe', 'r'),
1 => array('pipe', 'w'),
2 => array('pipe', 'w')
);
$process = proc_open($cmd, $descriptorspec, $pipes);
while (!feof($pipes[1])) {
echo fread($pipes[1], 80);
}
fclose($pipes[0]);
fclose($pipes[1]);
fclose($pipes[2]);
proc_close($process);
?>
Expected result:
----------------
getcwd:
C:\Apache2.2\htdocs
3 times a directory listing of:
C:\Apache2.2\htdocs
Actual result:
--------------
getcwd:
C:\Apache2.2\htdocs
2 times (popen, passthru) a directory listing of:
C:\Apache2.2\htdocs
1 time (proc_open) a directory listing of:
apache2handler: C:\Apache2.2
or CGI/FastCGI: C:\PHP
