PHP exec - missing output

Answer 1

Are you passing the second output array parameter?

http://us2.php.net/manual/en/function.exec.php

string exec ( string $command [, array &$output [, int &$return_var ]] )

output

If the output argument is present, then the specified array will be filled with every line of output from the command. Trailing whitespace, such as \n, is not included in this array. Note that if the array already contains some elements, exec() will append to the end of the array. If you do not want the function to append elements, call unset() on the array before passing it to exec().

Answer 2

I suspect you might be right that windows isn't liking the 2>&1 statement. What do you see when you try:

$output = array()
echo "Executing: [$path2sox/sox $cmd]";
exec("$path2sox/sox $cmd", $output, $result);
echo "Result: ";
var_dump($result);
echo "\n<br>Output: ";
var_dump(output);
