Parsing JSON Array PHP

Question

I have this output after json decode.

Array
 (
 [CJ] => stdClass Object
 (
 [CID] => 1234 
 [TYPE] => type2222
 [CURRENCY] => GBP
 [OID] => 100000037
 [DISCOUNT] => 0.00
 [PRODUCTLIST] => Array
 (
 [0] => stdClass Object
 (
 [ITEM] => TEST_PRO_02-White-M
 [QTY] => 2
 [AMT] => 80.00
 [DCNT] => 0.00
 )
 [1] => stdClass Object
 (
 [ITEM] => TEST_PRO_02-White-M
 [QTY] => 2
 [AMT] => 0.00
 [DCNT] => 0.00
 )
 [2] => stdClass Object
 (
 [ITEM] => TEST_PRO_01-Pink
 [QTY] => 1
 [AMT] => 135.00
 [DCNT] => 0.00
 )
 [3] => stdClass Object
 (
 [ITEM] => TEST_PRO_01-Pink
 [QTY] => 1
 [AMT] => 0.00
 [DCNT] => 0.00
 )
 )
 )
 )

I need to make a string to put values in iframe. it gives me no result but if i put quotes on json string it gives me required result.

$x=0;
foreach ($obj->CJ->PRODUCTLIST as $productlist){
 $item=$productlist->ITEM;
 $amount=$productlist->AMT;
 $qty=$productlist->QTY;
 $cj_string.="ITEM".$x."=$item&AMT".$x."=$amount&QTY".$x."=$qty&";
$x++;}

it gives me php nonobject parsing error. How do I get values from PRODUCTLIST in the form of

item1=value&QTY1=value&AMT1=value&item2=value&QTY2=value&AMT2=value

Solution for your question would be this,

$cjhelper = '{"CJ":{"CID":"1234","TYPE":"type2222","CURRENCY":"GBP","OID":"100000045","DISCOUNT":"0.00","PRODUCTLIST":[{"ITEM":"TEST_PRO_01-Pink","QTY":"1","AMT":"135.00","DCNT":"0.00"},{"ITEM":"TEST_PRO_01-Pink","QTY":"1","AMT":"0.00","DCNT":"0.00"}]}}';
$obj = json_decode($cjhelper);
$x=1;
$cj_string = "";
 foreach ($obj->CJ->PRODUCTLIST as $productlist){
 $item=$productlist->ITEM;
 $amount=$productlist->AMT;
 $qty=$productlist->QTY;
 if($x!=1) $cj_string.= "&";
 $cj_string.="ITEM".$x."=$item&AMT".$x."=$amount&QTY".$x."=$qty";
 $x++;
 }
echo $cj_string;

Your expected output will be

ITEM1=TEST_PRO_01-Pink&AMT1=135.00&QTY1=1&ITEM2=TEST_PRO_01-Pink&AMT2=0.00&QTY2=1

• Sasikumar: can you post the json string here
• Meshan Raza: cj-helper{"CJ":{"CID":"1234","TYPE":"type2222","CURRENCY":"GBP","OID":"100000045","DISCOUNT":"0.00","PRODUCTLIST":[{"ITEM":"TEST_PRO_01-Pink","QTY":"1","AMT":"135.00","DCNT":"0.00"},{"ITEM":"TEST_PRO_01-Pink","QTY":"1","AMT":"0.00","DCNT":"0.00"}]}}
• Meshan Raza: When I write your code as it is, it gives me required result. so basically my json string is missing single quotes. problem in json encoding?
• Meshan Raza: Where did i went wrong JSON string was made by JSON encoding with dynamic populated values. how i put these singlw quotes
