How can the order of Charset and Encoding affect the output of text in PHP, and what steps should be taken to ensure correct display?

The order of Charset and Encoding can affect the output of text in PHP by causing characters to display incorrectly or not at all. To ensure correct display, it is important to set the Charset and Encoding before outputting any text. This can be done by using the header() function to specify the Charset and Encoding. 

<?php
header('Content-Type: text/html; charset=utf-8');
echo "Hello, world!";
?>
