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

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;
}

?>

According to http://www.php.net/manual/en/sqlite3result.columntype.php, and also per my experience, columnType() doesn't return anything other than SQLITE3_NULL. Consequently, the test suggested in the comment that tries to identify whether a column is NULL is incorrect.

The right thing to do appears to be to test if ($result->fetchArray())[0] == null.

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