PHP array element need to output the same on my sample - php

Question

I have this code below that I want to make the output like this json:
[{avatarUrl: '',messages:
[{time: ,text: ''},
{time: ,text: ''},
{time: ,text: ''}]}
,{own: true,messages:
[{time: ,text: ''},
{time: ,text: ''},
{time: ,text: ''}]}
,{avatarUrl: '',messages:
[{time: ,text: ''},
{time: ,text: ''},
{time: ,text: ''},
{time: ,text: ''},
{time: ,text: ''}]}
,{own: true,messages:
[{time: ,text: ''},
{time: ,text: ''},
{time: ,text: ''}]}]
Because on my current codes the output is this, I also added the exact result of my mysql fetch array :
[{"avatarUrl":"assets\/img\/avatars\/avatar_02_tn.png","messages":[{"time":"2019-02-22 15:31:52","text":"hellooo"}]},
{"avatarUrl":"assets\/img\/avatars\/avatar_02_tn.png","messages":[{"time":"2019-02-22 15:31:54","text":"hi"}]},
{"avatarUrl":"assets\/img\/avatars\/avatar_02_tn.png","messages":[{"time":"2019-02-22 15:31:56","text":"yes"}]},
{"avatarUrl":"assets\/img\/avatars\/avatar_02_tn.png","messages":[{"time":"2019-02-22 15:31:58","text":"ano yun"}]},
{"avatarUrl":"assets\/img\/avatars\/avatar_02_tn.png","messages":[{"time":"2019-02-22 15:32:20","text":"jjj"}],"own":true},{"avatarUrl":"assets\/img\/avatars\/avatar_02_tn.png","messages":[{"time":"2019-02-22 15:32:22","text":"kasdkaskds"}],"own":true},{"avatarUrl":"assets\/img\/avatars\/avatar_02_tn.png","messages":[{"time":"2019-02-22 15:33:47","text":"yes"}],"own":true},{"avatarUrl":"assets\/img\/avatars\/avatar_02_tn.png","messages":[{"time":"2019-02-22 15:33:50","text":" WHatzz"}],"own":true},{"avatarUrl":"assets\/img\/avatars\/avatar_02_tn.png","messages":[{"time":"2019-02-22 15:33:51","text":"up"}],"own":true},{"avatarUrl":"assets\/img\/avatars\/avatar_02_tn.png","messages":[{"time":"2019-02-22 15:33:52","text":"jejes"}],"own":true},{"avatarUrl":"assets\/img\/avatars\/avatar_02_tn.png","messages":[{"time":"2019-02-22 15:33:53","text":"s"}],"own":true},{"avatarUrl":"assets\/img\/avatars\/avatar_02_tn.png","messages":[{"time":"2019-02-22 15:33:53","text":"ssSs"}],"own":true},{"avatarUrl":"assets\/img\/avatars\/avatar_02_tn.png","messages":[{"time":"2019-02-22 ...

And this is my code. I already add some trappings to copycat the exact format but I cant still replicate. Any idea or do I neeed to add some condition.
$json_response_list = array();
$json_response = array();
$json_msgx = array();
$own = 0;
$from = 0;
$mydata = "";
$ctr = 1;
$cx = 1;
$sql = "SELECT empfrom,empto,empmsg,xdatetime,xuser FROM chatbox WHERE xdelete = 0 AND (empto = '".$_POST['userto']."' OR empfrom = '".$_POST['userto']."') AND (empto = '".$_SESSION['crmuserid']."' OR empfrom = '".$_SESSION['crmuserid']."' ) ORDER BY xdatetime ASC";
$result = mysqli_query($conn1,$sql) or die(mysqli_error($sql));
while ($row = mysqli_fetch_array($result)) {
if($row['xuser']==$_SESSION['crmuserid']){
if($own==0){
$json_response['own'] = true;
$own = 1;
$from = 0;
$cx = 1;
}
}else{
if($from==0){
$json_response['avatarUrl'] = "assets/img/avatars/avatar_02_tn.png";
$from = 1;
$own = 0;
$cx = 1;
}
}
$json_response['messages'] = array();
$json_msgx['time'] = $row['xdatetime'];
$json_msgx['text'] = $row['empmsg'];
array_push($json_response['messages'],$json_msgx);
if($ctr!=1 && $cx==1){
array_push($json_response_list,$json_response);
}
$ctr++;
$cx++;
}
$jsonData = json_encode($json_response_list); //JSON_PRETTY_PRINT
echo $jsonData;

Answer 1

I found out that the json format that I want to achieve to be output is not possible, specially inside a loop because it will automatically replicate the non existing element of array. Below is the sample code I made to make it work.
$json_response_list = array();
$json_response = array();
$json_msgx = array();
$own = 0;
$from = 0;
$mydata = "";
$ctr = 1;
$cx = 1;
$sql = "SELECT empfrom,empto,empmsg,xdatetime,xuser FROM chatbox WHERE xdelete = 0 AND (empto = '".$_POST['userto']."' OR empfrom = '".$_POST['userto']."') AND (empto = '".$_SESSION['crmuserid']."' OR empfrom = '".$_SESSION['crmuserid']."' ) ORDER BY xdatetime ASC";
$result = mysqli_query($conn1,$sql) or die(mysqli_error($sql));
while ($row = mysqli_fetch_array($result)) {
if($row['xuser']==$_SESSION['crmuserid']){
if($own==0){
if($cx!=1 && $ctr!="1"){
array_push($json_response_list,$json_response);
}
$json_response['avatarUrl'] = "";
$json_response['own'] = "1";
$own = 1;
$from = 0;
$cx = 1;
$json_response['messages'] = array();
}
}else{
if($from==0){
if($cx!=1 && $ctr!="1"){
array_push($json_response_list,$json_response);
}
$json_response['avatarUrl'] = "assets/img/avatars/avatar_02_tn.png";
$json_response['own'] = "";
$from = 1;
$own = 0;
$cx = 1;
$json_response['messages'] = array();
}
}
$json_msgx['time'] = $row['xuser'];
$json_msgx['text'] = $row['xuser'];
array_push($json_response['messages'],$json_msgx);
$ctr++;
$cx++;
}
$jsonData = json_encode($json_response_list); //JSON_PRETTY_PRINT
echo $jsonData;
