jquery - PHP array string key add number at the end -

good day fellas!

i have block of code create json string , have dynamic number of data need dynamic name key..

if (mysql_num_rows($result) > 0) {     $response["members"] = array();     $x = 0;     $members = array();     while ($row = mysql_fetch_array($result)) {         $members = array();         $members["member" + (string)$x] = array();         $member["member_id"] = $row["member_id"];         $member["firstname"] = $row["firstname"];         $member["mi"] = $row["mi"];         $member["lastname"] = $row["lastname"];         $member["email"] = $row["email"];         $member["username"] = $row["username"];         $member["password"] = $row["password"];         $member["guild_id"] = $row["guild_id"];         $member["guild_name"] = $row["guild_name"];         $member["guild_code"] = $row["guild_code"];         array_push($members["member" + (string)$x], $member);         $x++;     }     array_push($response["members"], $members);      echo json_encode($response);; } 

in jquery type of method works.. question is, there way can achieve using php? if know happy know...

1.suggestion:-stop using deprecated+removed(php5 +php7) version of mysql_*.move towards mysqli_* or pdo along prepared statements(prevent sql injection)

2.why creating unnecessary array , multiple push.no need that.do below:-

$response["members"] = array();//put outside if (mysql_num_rows($result) > 0) {     $x = 0;     while ($row = mysql_fetch_array($result)) {         $response["members"][$x]["member_id"] = $row["member_id"]; //assign value directly resultant array         $response["members"][$x]["firstname"] = $row["firstname"];         $response["members"][$x]["mi"] = $row["mi"];         $response["members"][$x]["lastname"] = $row["lastname"];         $response["members"][$x]["email"] = $row["email"];         $response["members"][$x]["username"] = $row["username"];         $response["members"][$x]["password"] = $row["password"];         $response["members"][$x]["guild_id"] = $row["guild_id"];         $response["members"][$x]["guild_name"] = $row["guild_name"];         $response["members"][$x]["guild_code"] = $row["guild_code"];         $x++;     } }  if(count($response["members"])>0){ //check array not empty  echo json_encode($response); //echo json encoded array data }
