How can the use of consistent naming conventions for session variables improve code readability and prevent errors in PHP?

Using consistent naming conventions for session variables in PHP can improve code readability and prevent errors by ensuring that variables are named in a systematic and predictable way. This makes it easier for developers to understand the purpose of each variable and reduces the likelihood of naming conflicts or typos. By following a naming convention such as using all lowercase letters with underscores for spaces (e.g., $_SESSION['user_id']), developers can maintain a cleaner and more organized codebase. 

// Example of using consistent naming conventions for session variables
session_start();

// Set session variable for user ID
$_SESSION['user_id'] = 123;

// Retrieve and display user ID
echo $_SESSION['user_id'];
