How to background a process via proc_open and have access to STDIN?

Question

I\'m happily using proc_open to pipe data into another PHP process. something like this

$spec = array (
    0 => array(\'pipe\', \'r\'),
    // I         


        

Answer 1

You can't write to STDIN of a background process (at least, not in the normal way).

This question on Server Fault may give you some idea of how to work around this problem.

Unrelated: you say do don't need outputs in the spec, yet you specify them im your $cmd; you can write $spec like this:

$spec = array (
    0 => array('pipe', 'r'),
    1 => array('file', 'out.log', 'w'), // or 'a' to append
    2 => array('file', 'err.log', 'w'),
);
