PHP redirect loop issue - php

Question

When I submit my category search form, I want it to run the php code in the DisplayMealsCont.php and then go back to the main.php with the updated session variables. But when I try to put in a Header("Location: ../View/Main.php"); in the DisplayMealsCont.php it gets stuck in a redirect loop.
main.php
<?php
require_once("../Controller/DisplayMealsCont.php");
session_start();
$category = "All";
if(isset($_SESSION['table'])){
$table = $_SESSION['table'];
}
if(isset($_SESSION['Category'])){
$category = $_SESSION['Category'];
if($category == "All"){
$category = " ";
}
}
?>
<?php
if (is_array($table)) {
foreach($table as $item) {
?>
<td align="centre"> <?= $item['Meal_Name'] ?> </td>
<td align="centre"> <?= $item['Description'] ?> </td>
<td align="centre"> <?= $item['Image'] ?> </td>
<td align="centre"> <?= $item['Category'] ?> </td>
<td align="centre"> <?= $item['Quantity'] ?> </td>
<td align="centre"> £ <?= $item['Price'] ?> </td>
<tr>
<?php
}
}
?>
</table>
<form method="post" action="../Controller/DisplayMealsCont.php">
Category: <br />
<select name="Category">
<option value="All">All</option>
<option value="Main">Main</option>
<option value="Drink">Drinks</option>
</select> <br />
<input type="submit" name="categorysubmit" value="Search" />
</form>
DisplayMealModel.php
<?php
require_once("../Model/config.php");
class DisplayMeals
{
public $dbConnection;
public function __construct(){
$db= new database();
$connect=$db->getdatabase();
$this->dbConnection = $connect;
}
public function MainMeals($category){
$_SESSION['test'] = $category;
$stmt = $this->dbConnection->prepare("SELECT * from meal WHERE Category LIKE '$category%'");
$stmt->execute();
return $stmt->fetchAll(PDO::FETCH_ASSOC);
}
?>
DisplayMealCont.php
<?php
require("../Model/DisplayMealModel.php");
$newMeal = new DisplayMeals();
if(!isset($category)){
$category = "main";
}
if(isset($_SESSION['Category'])){
$category = $_SESSION['Category'];
}
$table = $newMeal-> MainMeals($category);
$_SESSION['table'] = $table;
?>

I can't see why a header() in there causes a redirection loop, but have you tried adding a die(); after header()?
It's a good practice, and in case it works it may shed light into what is causing the issue. Other than that, it would help if you posted the code with the looping header in it so we can see.
