What are the potential risks of using the exit function in PHP scripts and how can they be avoided?

The potential risk of using the exit function in PHP scripts is that it can abruptly terminate the script, potentially causing unexpected behavior or leaving tasks unfinished. To avoid this risk, it is recommended to refactor the code to handle any necessary cleanup or redirection before exiting the script.

// Avoid using exit function and refactor the code to handle cleanup or redirection before exiting

// Example of refactored code:
if ($condition) {
    // Perform necessary tasks
    // Redirect to a different page
    header("Location: new_page.php");
    exit; // This line is safe to use after handling necessary tasks
}
