How can the EVA principle in PHP development help prevent issues like session cookies not being created properly?

Session cookies not being created properly can be prevented by following the EVA principle in PHP development, which stands for Error handling, Validation, and Authentication. By properly handling errors, validating user input, and authenticating users, developers can ensure that session cookies are created and maintained correctly. 

<?php

// Start the session
session_start();

// Set session variables
$_SESSION['username'] = 'example_user';

// Check if session cookie is set
if(isset($_COOKIE[session_name()])) {
    echo "Session cookie is set!";
} else {
    echo "Session cookie is not set!";
}

?>
