PHP: Appending an array to an array

Question

First of all, sorry if this sounds like a rather commonly asked question, but I've looked all over without finding something satisfactory.

This is my code:

$query = mysql_query("SELECT * FROM Rezept");
            $allRecipes = array();
            for($i = 0; $i < mysql_num_rows($query); $i++){
                $average = 0;
                $row = mysql_fetch_row($query);
                $review = mysql_query("Select Stern FROM Bewertung WHERE Rezept_NR LIKE ". $row[0]);
                for($n = 0; $n < mysql_num_rows($review); $n++){
                    $stern = mysql_fetch_row($review);
                    $average += $stern[3];
                }
                $average /= mysql_num_rows($review);
                $recipe = array(
                    "Name" => $row[2],
                    "Kurzb" => $row[3],
                    "Bild" => $row[4],
                    "Bewertung" => $average
                );
                $allRecipes = array_merge_recursive($allRecipes, $recipe);
            }
            print_r($allRecipes);
}

Anyway. What I get:

Array ( [Name] => Array ( [0] => Test [1] => Teeeest [2] => Test [3] => Test [4] => Test [5] => Test [6] => Test [7] => Test [8] => Test [9] => Test [10] => Test [11] => Test [12] => Test [13] => Test [14] => Tests [15] => Tests [16] => Tests ) [Kurzb] => Array ( [0] => Tes [1] => Testtest [2] => Test [3] => Test [4] => Test [5] => Test [6] => Test [7] => Test [8] => Test [9] => Test [10] => Test [11] => Test [12] => LOLTest [13] => Test [14] => Testersersts [15] => Testersersts [16] => Testersersts ) [Bild] => Array ( [0] => [1] => [2] => [3] => [4] => [5] => [6] => [7] => [8] => [9] => [10] => [11] => [12] => [13] => [14] => [15] => [16] => ) [Bewertung] => Array ( [0] => [1] => [2] => 0 [3] => [4] => [5] => [6] => [7] => [8] => [9] => [10] => [11] => [12] => [13] => [14] => [15] => [16] => ) )

It's pretty close, but not what I'm looking for.

What I want:

Array([0] => array([Name] => Test [Kurzb] => Test [Bild] => something) [1] => array([Name] => Test [Kurzb] => Test [Bild] => something))

Is it a problem that I'm trying to use multiple arrays with the same keys? Am I aproaching this with the wrong idea? I'm a complete newbie when it comes to programming...

Use array_combine for this...

$a = array('green', 'red', 'yellow');
$b = array('avocado', 'apple', 'banana');
$c = array_combine($a, $b);

This would return:

Array
(
    [green]  => avocado
    [red]    => apple
    [yellow] => banana
)

So in your code, change this:

$allRecipes = array_combine($allRecipes, $recipe);

Nevermind that, I found that "$allRecipes[$i] = $recipe;" works just as I needed it right after submitting. Thanks though.

    $query = mysql_query("SELECT * FROM Rezept");
    $i =0;
    while(($result = mysql_fetch_row($query)) !== FALSE) 
    {
        $newArray[$i][] = $result; 
        $i++;
    }
    return $newArray;

1 simply just query db 2 fetch it with while.
