Description:
------------
proc_open.c checks if the mode parameter != "w" instead of checking the
first character of the mode parameter. This prevents the mode 'wb' from
working properly.
Reproduce code:
---------------
<?php
$pipes = array();
$descriptor_spec = array(
0 => array('pipe', 'rb'),
1 => array('pipe', 'wb'),
);
$proc = proc_open('cat', $descriptor_spec, $pipes);
fwrite($pipes[0], 'Hello', 5);
fflush($pipes[0]);
fclose($pipes[0]);
$result = fread($pipes[1], 5);
fclose($pipes[1]);
proc_close($proc);
echo "Result is: ", $result, "\n";
?>
Expected result:
----------------
Result is: Hello
Actual result:
--------------
on stderr:
cat: write error: Bad file descriptor
on stdout:
Result is:
------------------------------------------------------------------------
