How can PHP developers ensure that their code remains UTF-8 encoded and properly displayed in HTML?
To ensure that PHP code remains UTF-8 encoded and properly displayed in HTML, developers can set the default character encoding to UTF-8 using the header() function in PHP. This will ensure that any text output by PHP is encoded in UTF-8 and displayed correctly in HTML.
<?php
header('Content-Type: text/html; charset=utf-8');
?>
