When using this package I have:

PHP Warning:  Invalid argument supplied for foreach() in vendor/dbdiff/dbdiff/src/DB/Data/ArrayDiff.php on line 47
PHP Warning:  Invalid argument supplied for foreach() in vendor/dbdiff/dbdiff/src/DB/Data/ArrayDiff.php on line 79
PHP Warning:  Invalid argument supplied for foreach() in vendor/dbdiff/dbdiff/src/DB/Data/ArrayDiff.php on line 88

PHP 7.4.25
10.6.5-MariaDB-1:10.6.5+maria~focal
WSL2 Debian

$data1 = $this->dbiterator1->next(ArrayDiff::$size); return a Collection and array_merge require an array.

Unless using $data1->toArray() others errors occurs.

First patch attempt:

ArrayDiff.php line 40

    public function isKeyEqual( $entry1, $entry2 ) {
        // patch -->
        if ( null === $entry1 || null === $entry2 ) {
            return false;
        }
        // <- patch
        foreach ( $this->key as $key ) {
            if ( $entry1[ $key ] !== $entry2[ $key ] ) {
                return false;
            }
        }

        return true;
    }

It returns a larger file with more data.
