Insert new array to php json -

i tried push new array value json

$var=array("code"=>"100"); $sql = select order orderid, pub ordercode cart while ($row = mysql_fetch_assoc ($sql) { $var[] = $row; } echo '{"status":'. json_encode($var).'}'; 

i want push string json array above

$string = array("total"=>"3000"); 

and script displays this:

{   "status":{      "code":"100",       "0":{               "total":"3000"           },       "1":{               "orderid":"16",             "ordercode":"14290290685322"           },       "2":{               "total":"3000"           }       }    } 

and want var total inside this:

**////////blablabla    "1":{        "orderid":"16",       "ordercode":"14290290685322",       "total":"3000"        } *///blablba 

add $var[] = array("total"=>"3000"); before encode json

$var=array("code"=>"100"); $sql = select order orderid, pub ordercode cart while ($row = mysql_fetch_assoc ($sql) {   $row['total'] = '3000' ;   $var[] = $row; } echo '{"status":'. json_encode($var).'}';
