Question

I have a PHP MySQL fetch while loop as shown below in my script:

$result2211 = mysql_query("select * from products where is_config = 'yes' ");
while($row2211 = mysql_fetch_assoc($result2211))
{
   $sn = $row2211['sn'];
   $allparrentselectq = mysql_query("SELECT * FROM parrentpro where parrentsn = $sn");
   while($allparrentselect = mysql_fetch_assoc($allparrentselectq))
   {
       $childarr = unserialize($allparrentselect['childsn']);
       $subpro  = '{"catname":"'.$allparrentselect['childname'].'",';
       $i = 0;
       foreach($childarr as $childarr):
           $subpro .= '"Pro'.$i++.'":"'.$childarr.'",';
       endforeach;
       $subpro1[] = substr($subpro, 0, -1)."}";
       $subproa = "[".implode(",",$subpro1)."]";
   }
   $prodObj2 = new ProductDetails();
   $prodObj2->productname = $row2211['productname'];
   $prodObj2->price = $row2211['productprice'];
   $prodObj2->discount = $row2211['discount'];
   $prodObj2->discountprice = $row2211['discountprice'];
   $prodObj2->imageURL = $row2211['productimageurl'];
   $prodObj2->category = $row2211['productcat'];
   $prodObj2->configurablepone = $subproa;
   $prodObj2->configurable = 'yes';
   array_push($totArr, $prodObj2);
}

In that I have a problem. I get the result as like below (JSON):

[
    {
        "productname":"Veg.Pizaa",
        "price":"350",
        "discount":"",
        "discountprice":"350",
        "imageURL":"http:\/\/farm8.staticflickr.com\/7154\/6694188161_9ee692d854_s.jpg",
        "category":"Pizaa",
        "configurablepone":[{"catname":"Extra","Pro0":"Extra 25g Cheese","Pro1":"Extra 75g Cheese"},"catname":"Nuts","Pro0":"Almonds","Pro1":"Peanuts","Pro2":"Pistachios"}],
        "configurable":"yes"
    },
    {
        "productname":"Core i7 Pc",
        "price":"48000",
        "discount":"2",
        "discountprice":"47040",
        "imageURL":"http:\/\/www.4to40.com\/images\/science\/Basic_Computer_Parts\/Computer.jpg",
        "category":"Pc",
        "configurablepone":[{"catname":"Extra","Pro0":"Extra 25g Cheese","Pro1":"Extra 75g Cheese"},{"catname":"Nuts","Pro0":"Almonds","Pro1":"Peanuts","Pro2":"Pistachios"},{"catname":"Harddisk","Pro0":"Segate 500Gb","Pro1":"Samsung 250Gb"},{"catname":"Ram","Pro0":"8Gb Ram","Pro1":"4Gb Ram","Pro2":"2Gb Ram"}],
        "configurable":"yes"
    }
]

But I need the result as like below:

[
    {
        "productname":"Veg.Pizaa",
        "price":"350",
        "discount":"",
        "discountprice":"350",
        "imageURL":"http:\/\/farm8.staticflickr.com\/7154\/6694188161_9ee692d854_s.jpg",
        "category":"Pizaa",
        "configurablepone":[{"catname":"Extra","Pro0":"Extra 25g Cheese","Pro1":"Extra 75g Cheese"},"catname":"Nuts","Pro0":"Almonds","Pro1":"Peanuts","Pro2":"Pistachios"}],
        "configurable":"yes"
    },
    {
        "productname":"Core i7 Pc",
        "price":"48000",
        "discount":"2",
        "discountprice":"47040",
        "imageURL":"http:\/\/www.4to40.com\/images\/science\/Basic_Computer_Parts\/Computer.jpg",
        "category":"Pc",
        "configurablepone":[{"catname":"Harddisk","Pro0":"Segate 500Gb","Pro1":"Samsung 250Gb"},{"catname":"Ram","Pro0":"8Gb Ram","Pro1":"4Gb Ram","Pro2":"2Gb Ram"}],
        "configurable":"yes"
    }
]

As you can see configurablepone JSON is getting repeated for every loop so I am getting the value of the first product in second product also but I need to seperate like below:

First Product As Like Below

"configurablepone":[{"catname":"Extra","Pro0":"Extra 25g Cheese","Pro1":"Extra 75g Cheese"},{"catname":"Nuts","Pro0":"Almonds","Pro1":"Peanuts","Pro2":"Pistachios"}]

Second Product As Like Below

"configurablepone":[{"catname":"Harddisk","Pro0":"Segate 500Gb","Pro1":"Samsung 250Gb"},{"catname":"Ram","Pro0":"8Gb Ram","Pro1":"4Gb Ram","Pro2":"2Gb Ram"}]

I have tried changing the loop but I haven’t found any solutions. Kindly help me to solve this.

Just Use unset($subpro1); after the array_push($totArr, $prodObj2);.
Below Is An example Source
Try This One This May Work

$result2211 = mysql_query("select * from products where is_config = 'yes' ");
while($row2211 = mysql_fetch_assoc($result2211))
{
   $sn = $row2211['sn'];
   $allparrentselectq = mysql_query("SELECT * FROM parrentpro where parrentsn = $sn");
   while($allparrentselect = mysql_fetch_assoc($allparrentselectq))
   {
       $childarr = unserialize($allparrentselect['childsn']);
       $subpro  = '{"catname":"'.$allparrentselect['childname'].'",';
       $i = 0;
       foreach($childarr as $childarr):
           $subpro .= '"Pro'.$i++.'":"'.$childarr.'",';
       endforeach;
       $subpro1[] = substr($subpro, 0, -1)."}";
       $subproa = "[".implode(",",$subpro1)."]";
   }
   $prodObj2 = new ProductDetails();
   $prodObj2->productname = $row2211['productname'];
   $prodObj2->price = $row2211['productprice'];
   $prodObj2->discount = $row2211['discount'];
   $prodObj2->discountprice = $row2211['discountprice'];
   $prodObj2->imageURL = $row2211['productimageurl'];
   $prodObj2->category = $row2211['productcat'];
   $prodObj2->configurablepone = $subproa;
   $prodObj2->configurable = 'yes';
   array_push($totArr, $prodObj2);
   unset($subpro1);
}
