zwei Tabellen kombinieren und 2 Tabellen in einem Array

Question

Ich habe ihre Daten anzeigen: Produkt und Wagen, ich mag diese zwei Tabellen kombinieren und zeigen die Daten in einem Array nach einem bestimmten Zustand, wie folgt:

alle Produkte, die unter einer bestimmten Kategorie erhalten sollen, angezeigt und wenn ein bestimmte Benutzer hat jedes Produkt unter den gegebenen Produkten gekauft dann seine Einzelheiten sollten auch vor diesem Produkt

der Code, den ich bis zur Ausschöpfung angezeigt zu erledigen jetzt ist

$catid = $_REQUEST['catid']; 
$userid  = $_REQUEST['userid']; 

$sql = "select * from productsize where catid = '".$catid."' GROUP BY productid"; 
$result = mysqli_query($con, $sql); 
if (mysqli_num_rows($result) > 0) 
    { 
     while($row = mysqli_fetch_assoc($result)) 
      { 
       $rows['catid'] = $row['catid']; 
       $rows['catname'] = $row['catname']; 
       $rows['productid'] = $row['productid']; 
       $rows['prodname'] = $row['prodname']; 
       $rows['prodimg'] = $row['prodimg']; 
       $row2[]=$rows; 
      } 
    } 

echo "<pre>"; 
print_r($row2); 
echo "</pre>"; 

Es gibt ein Array wie diese

Array 
(
    [0] => Array 
     (
      [catid] => 2 
      [catname] => C1 
      [productid] => 13 
      [prodname] => P1 
      [prodimg] => 
     ) 

    [1] => Array 
     (
      [catid] => 2 
      [catname] => C1 
      [productid] => 14 
      [prodname] => P1 
      [prodimg] => 
     ) 

    [2] => Array 
     (
      [catid] => 2 
      [catname] => C1 
      [productid] => 15 
      [prodname] => P3 
      [prodimg] => 
     ) 

) 

Aber die endgültige Anordnung, die ich anstelle der oben Array wollen, ist

Array 
(
    [0] => Array 
     (
      [catid] => 2 
      [catname] => C1 
      [productid] => 13 
      [prodname] => P1 
      [prodimg] => 
      [size] => Array 
       (
        [0] => small 
        [1] => medium 
        [2] => large 
        [3] => perpiece 
       ) 
      [cost] => Array 
       (
        [0] => 10 
        [1] => 20 
        [2] => 30 
        [3] => 12 
       ) 
      [purchasedsize] => Array

       ) 
      [userid] => 1 
     )

       ) 
      [purchasedquantity] => Array 
       (
        [0] => 0 
        [1] => 1 
        [2] => 0 
        [3] => 0 
       ) 
      [userid] => 1 
     ) 

    [2] => Array 
     (
      [catid] => 2 
      [catname] => C1 
      [productid] => 15

       (

        [3] => perpiece 
       ) 
      [cost] => Array 
       (
        [0] => 0 
        [1] => 20 
        [2] => 0

       ) 
      [purchasedsize] => Array 
       (
        [0] => 0 
        [1] => 0 
        [2] => 0 
        [3] => 0

Kann jemand bitte helfen Sie mir die gewünschte Array als Ergebnis zu bekommen?
