How can the misuse of the header("Refresh:0") function lead to unexpected behavior in PHP applications?

Misusing the header("Refresh:0") function in PHP can lead to unexpected behavior by causing the page to continuously refresh, creating an infinite loop. To solve this issue, it is important to use the header("Location: <url>") function instead to redirect the user to a different page after a certain amount of time.

// Correct way to redirect to a different page after 5 seconds
header("Refresh:5; url=redirect_page.php");
exit();
