json_encode不想提供数据（或其他错误）

New here and new to coding (kinda). I'm learing by making practical db. Part of code are from tutorials but i understand why and how it works mostly and if not world is full with answers, and most of them here :)

With this particular problem, i believe i just miss something and need fresh look because i'm stuck for 3 days and don't see why it's not working by myself.

Problem: Fetch.php was fetching data from sql and give it to main.php by echo $output (html code). Then I decided I want to make my own paging system and need to get rowcount from fetch.php too. So and json_encode to fuction and dataType: json to caller. And it shoud work but not retrieve any data. It works just fine with other mine function.

So what do i don't see?

P.S. I put alerts before ajax and after and inside success function. First two are triggering. So I assume something wrong with fetch and it don't want to return data.

P.P.S. function fetch_pasutijumi doesn't get anything from echo json_encode($out); ... without dataType:'json', in ajax request and with echo ($outputs) (without using array) it works and html data is given back.

function fetch_pasutijumi(query, lim, from)
  {
    $.ajax({
    url:"fetch_pasutijumi.php",
    method:"POST",
    data:{query:query, lim:lim, from: from},
    dataType:'json',
    success:function(data)
    {
      result = data.outputs;
      $("#result").html(result);
    }
    });
  }


if(isset($_POST["query"]))
   {
      $lim = $_POST["lim"];
      $from = $_POST["from"];
      $search = $_POST["query"];
      $sql = "SELECT job.id AS id, job.red_nr as red_nr, job.name as name, date(job.date) as date, status.name as status_name FROM job LEFT JOIN status ON job.status_id = status.id WHERE job.red_nr LIKE '%".$search."%' OR job.name LIKE '%".$search."%' ORDER BY job.id DESC LIMIT ".$from.", ".$lim;
   }
   else
   {
     $sql = "SELECT job.id AS id, job.red_nr as red_nr, job.name as name, date(job.date) as date, status.name as status_name FROM job LEFT JOIN status ON job.status_id = status.id ORDER BY job.id DESC LIMIT ".$from.", ".$lim;
   } 
$outputs = '
  <table class="tbl_1">
        <tr class="tbl_head">
            <th>Red NR</th> 
            <th>Nosaukums</th>
            <th>Datums</th>
            <th>Status</th>
            <th><div name="" id=""></th>
            <th></th>
        </tr>
'; 
$query = $pdo->prepare($sql);
$query->execute();
$result = $query->fetchAll();
$total_row = $query->rowCount();


if($total_row > 0)
{
  $outputs .='

      </td>
    </tr>
  ';

  foreach($result as $row)
 {

  $date = date_create($row["date"]);

  $outputs .= '
    <tr class="tbl_row" id="'.$row["id"].'">
      <td class="td_red_nr"><div id="red'.$row["id"].'">'.$row["red_nr"].'</div></td>

      </td>
    </tr>
  ';
 }
 $outputs .='</table>';
 $out['outputs'] = $outputs;
 echo json_encode($out);
}
else
{
 $out['outputs'] = $outputs;
 echo json_encode($out);
}

What a ...

Problem was that json_encode somehow don't like <html> tag in php file!!! Who could imagine that?

I removed both html tags and it started to work as it should be 3 days ago. There is no such problem with echo $something to ajax.
