Here's a snippet that might help you to write a fetchObject function that is also missing:

<?php

function fetchObject($sqlite3result, $objectType = NULL) {
    $array = $sqlite3result->fetchArray();

    if(is_null($objectType)) {
        $object = new stdClass();
    } else {
        // does not call this class' constructor
        $object = unserialize(sprintf('O:%d:"%s":0:{}', strlen($objectType), $objectType));
    }
   
    $reflector = new ReflectionObject($object);
    for($i = 0; $i < $sqlite3result->numColumns(); $i++) {
        $name = $sqlite3result->columnName($i);
        $value = $array[$name];
       
        try {
            $attribute = $reflector->getProperty($name);
           
            $attribute->setAccessible(TRUE);
            $attribute->setValue($object, $value);
        } catch (ReflectionException $e) {
            $object->$name = $value;
        }
    }
   
    return $object;
}

?>

Heavily inspired of Bergmann's Object Freezer :

fetchArray() will return bool(false) in case of 0 rows.

Since SQLite3Result::numRows is unavailable, use:

<?php
if ($res->numColumns() && $res->columnType(0) != SQLITE3_NULL) {
    // have rows
} else {
    // zero rows
}
?>

Because when there are zero rows:
* SQLite3Result::fetchArray will return '1'
* SQLite3Result::numColumns will return '1'
* Column type for column '0' will be SQLITE3_NULL
