How can PHP developers ensure that their output pages are correctly encoded with utf-8 for proper display?

To ensure that PHP output pages are correctly encoded with utf-8 for proper display, developers can set the content type header to specify utf-8 encoding. This can be done using the header() function in PHP before any output is sent to the browser. Additionally, developers should make sure that their PHP files are saved with utf-8 encoding to avoid any issues with character encoding. 

<?php
header('Content-Type: text/html; charset=utf-8');
?>
