This is it:

$array1 = array("2"=> array("1"=>"2", "2"=>"4", "3"=>"9"),
                "3"=> array("1"=>"4", "2"=>"6", "3"=>""),
                "4"=> array("1"=>"4", "2"=>"6", "3"=>"7"),
                "5"=> array("1"=>"2", "2"=>"4", "3"=>"")
                );

$array2 = array("3"=> array("1"=>"2", "2"=>"4", "3"=>"9"),
                "5"=> array("1"=>"4", "2"=>"6", "3"=>"7")
                );

foreach ($array1 as $key => $value) {
    foreach ($value as $key2 => $value2) {
        if($value2 == ""){
            $array1[$key][$key2] = $array2[$key][$key2];
        }
    }
}
echo '<pre>';
print_r($array1);
echo '</pre>';

Output:

Array
(
    [2] => Array
        (
            [1] => 2
            [2] => 4
            [3] => 9
        )

    [3] => Array
        (
            [1] => 4
            [2] => 6
            [3] => 9
        )

    [4] => Array
        (
            [1] => 4
            [2] => 6
            [3] => 7
        )

    [5] => Array
        (
            [1] => 2
            [2] => 4
            [3] => 7
        )

)
