What is the purpose of setting the content-type to text/html; charset=utf-8 in PHP?

Setting the content-type to "text/html; charset=utf-8" in PHP is important because it specifies the character encoding of the HTML document being sent to the browser. This ensures that the browser interprets the text correctly, especially for special characters or non-ASCII characters. It helps prevent issues with character encoding mismatches and ensures that the HTML content is displayed correctly to the user.

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