New Comment:
No change...still runs like mad and crashes IIS. I can't even do a
"net stop". I'm running the CGI version if that makes any difference.
Also I have to refer to php as c:/php/php otherwise error-output.txt
has the message "he name specified is not recognized as an internal or
external command, operable program or batch file."

proc_open hangs on the example that is in the manual. Here is the
code.
$descriptorspec = array(
0 => array("pipe", "r"), // stdin is a pipe that the child will
read from
1 => array("pipe", "w"), // stdout is a pipe that the child will
write to
2 => array("file", "c:/temp/error-output.txt", "a"), // stderr
is a
file to write to
);
$process = proc_open("c:\php\php.exe", $descriptorspec, $pipes);
if (is_resource($process)) {
// $pipes now looks like this:
// 0 => writeable handle connected to child stdin
// 1 => readable handle connected to child stdout
// Any error output will be appended to /tmp/error-output.txt
fwrite($pipes[0], "<?php echo \"Hello World!\"; ?>" . chr(3));
fclose($pipes[0]);
while(!feof($pipes[1])) {
echo fgets($pipes[1], 1024);
}
fclose($pipes[1]);
// It is important that you close any pipes before calling
// proc_close in order to avoid a deadlock
$return_value = proc_close($process);
echo "command returned $return_value\n";
}
I'm running NT4 Server/PHP4.3.2.2/IIS4. This bit of code opened up 54
php.exe/cmd.exe (that's 54 of each or 108 total) processes on my
machine.
