How to LEFT JOIN more than 61 tables pup MySQL

I generated a large data query (one query ) more than 61 of type LEFT JOIN and now I can't continue how to solve this problem I need to add more tables.

My query is as follows:

<?php
require_once 'connt.php';

$id=$_GET['id'];


$sql="SELECT  * FROM topics
LEFT JOIN #########
LEFT JOIN #########
LEFT JOIN #########
LEFT JOIN #########
LEFT JOIN #########
LEFT JOIN #########
LEFT JOIN #########
LEFT JOIN ######### 
..ect


where topics.id = ? " ;

$stmt = $con->prepare($sql); 

$stmt->bind_param("s",$id);

$stmt->execute();

$result = $stmt->get_result();


$array = array();

while ($row  = mysqli_fetch_assoc($result))
{
    $array[] = $row;
}


echo ($result) ?
json_encode(array("code" => 1, "result"=>$array)) :
json_encode(array("code" => 0, "message"=>"Data not found !"));


?>

Also, is my way of working wrong? Is there a better way? Does this mean that the query will be slow?
