What are common reasons for receiving a 403 Forbidden error when trying to access JSON output from a PHP script using a C# HTTP GET request?

The most common reasons for receiving a 403 Forbidden error when trying to access JSON output from a PHP script using a C# HTTP GET request are incorrect file permissions on the server, misconfigured server settings, or missing authentication credentials. To solve this issue, ensure that the PHP script has the appropriate permissions to be accessed, check the server configuration for any restrictions on accessing JSON files, and provide any necessary authentication credentials in the C# HTTP GET request. 

<?php
header('Access-Control-Allow-Origin: *');
header('Content-Type: application/json');

// Your JSON data here
$data = array(
    'key1' => 'value1',
    'key2' => 'value2'
);

echo json_encode($data);
?>
