So this is my code, fetching the result of the query i need

$json_array = array();
$sql = "call rep_info();";
$result = $connect->query($sql);
while ($row = $result->fetch_assoc()) {
  $json_array[] = $row;
}

mysqli_free_result($result);  
mysqli_next_result($connect); 

// Buat info user
$json_array2 = array();
$sql = "call rep_user();";

$result = $connect->query($sql);
while ($row = $result->fetch_assoc()) {
  $json_array2[]["user"] = $row;
}

Then i merged the two arrays into one like this

$timeline = array_merge($json_array[0],$json_array2[0]);
$timeline2 = array_merge($json_array[1],$json_array2[1]);

$timeline = array_merge($timeline,$timeline2);

Encoded the merged array as well as echoing the variable

$encoded = json_encode($timeline);

echo $encoded;

So basically what i want is displaying 2 rows of the query result which is from json_array[0] and json_array[1]. But i only get 1 row in the echo result which the json_array[1] and json_array2[1].

What is the problem in this code? Thanks!

EDIT:

print_r($json_array[0]);
print_r($json_array2[0]);
