How can error reporting be used to identify and troubleshoot cookie-related problems in PHP?

Error reporting in PHP can be used to identify and troubleshoot cookie-related problems by enabling error reporting to display any errors or warnings related to cookie handling in the code. This can help pinpoint where the issue lies, such as incorrect cookie names or values being set, expired cookies, or improper cookie handling functions being used. By checking the error messages and debugging the code, developers can quickly identify and resolve cookie-related problems in PHP. 

<?php
// Enable error reporting to display any errors or warnings
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Set a cookie with a name and value
setcookie("example_cookie", "example_value", time() + 3600, '/');

// Check if the cookie is set and display its value
if(isset($_COOKIE['example_cookie'])) {
    echo "Cookie value: " . $_COOKIE['example_cookie'];
} else {
    echo "Cookie not set";
}
?>
