highcharts tables

Sorry I wanted to know how to spend a sum of hours thrown at me this query

SELECT form_matto.id_tecnico, SEC_TO_TIME(SUM(TIME_TO_SEC(tiempom))) as cuantas, 
tecnico.nombre FROM form_matto, tecnico where form_matto.id_tecnico in ('1','2','3','4') 
AND form_matto.id_tecnico = tecnico.id_tecnico 
AND (fecha >= '2018-01-01' AND fecha <= '2018-01-02' ) 
GROUP BY id_tecnico

This gives me the total hours of the field ' tiempom ' of the table 'form_matto'.

What I want is to pass the result to a graph of highcharts , but the code that I have of the graph does not give me the result of the query.

This is my code of the highcharts

<?php 
include("funciones.php");
include("console.php");
include("dbconnect.php");
session_start();
//----------RECUPERACION DE DATOS ENVIANDOS DESDE EL FORMULARIO------------

 $fechaIni= htmlspecialchars($_POST['fecha1'], ENT_QUOTES);
 $fechaFin= htmlspecialchars($_POST['fecha2'], ENT_QUOTES);
 //echo Console::log('Departamento', $Departamento);
 $dataArray;
 $i=0;
 $sql = $conn->prepare("SELECT form_matto.id_tecnico,  
 SEC_TO_TIME(SUM(TIME_TO_SEC(tiempom))) as cuantas, tecnico.nombre FROM  
 form_matto, tecnico where form_matto.id_tecnico in ('1','2','3','4') 
 AND form_matto.id_tecnico = tecnico.id_tecnico 
 AND (fecha >= ? AND fecha <= ? ) 
 GROUP BY id_tecnico");'

 $sql->bindParam(1,$fechaIni, PDO::PARAM_INT);
 $sql->bindParam(2,$fechaFin, PDO::PARAM_INT);
 $sql->execute();

 if ($sql->rowCount () > 0){
 while($rows=$sql->fetch(PDO::FETCH_ASSOC)){
 $no_registrosArray[$i]=$rows['cuantas'];
 $dataArray[$i] = "{ name:'".$rows['nombre']."',   
 y:".$rows['cuantas']."}";
  echo Console::log('ArrayNoRegistros', $dataArray[$i]);
  $i++;
}
