Hi,
I mentioned this a week or so ago, but had no response.
I have in mind a function that can work something like this:
$options = array(
0 => array("pipe", "r") // Stdin for new proc will be a pipe
1 => array("pipe", "w") // Stdout for new proc will be a pipe
2 => null, // Stderr will be /dev/null
3 => array("/path/to/other/file", "w") // fd 3 will be set to that of the
// file handle
);
The "w" or "r" are the modes with respect to the newly created process,
so stdin would be readable, stdout and fd #3 writeable by the new process.
$handles = proc_open($command_line, $options);
Where $handles is an array of file handles that can be used to talk
to the new process:
$handles = array(
0 => $fpstdin, // PHP can write to this to send to process
1 => $fpstdout, // PHP can read from this to get process output
);
This allows much greater control over the input/output of the process,
and allows more security/flexibility when using something like gpg and
passing passphrases to, or reading status messages from alternate
fd's.
I'm going to try and hack something together with this weekend; if
anyone has comments or suggestions, please drop me a line.
