The other answers did not work well with associative arrays. This recursive functions will trim all values inside a $_POST array all levels down.

// Trim all values of associative array
function trim_associative_array(&$input_array) {
    if (is_array($input_array)) {
        foreach ($input_array as $key => &$val) {
            if (is_array($val)) {
                trim_associative_array($val);
            } else {
                $input_array[$key] = trim($val);
            }
        }
    }
}
