What potential issues can arise when using header redirection in PHP, as seen in the provided code snippet?

Potential issues that can arise when using header redirection in PHP include "headers already sent" errors, where PHP outputs content before the header function is called. To solve this issue, it is important to ensure that no output is sent before using the header function. 

<?php
ob_start(); // Start output buffering

// Your PHP code here

ob_end_clean(); // Clean (erase) the output buffer
header("Location: new_page.php"); // Redirect to new page
exit; // Ensure no further code is executed after redirection
?>
