What steps can be taken to ensure that PHP files are saved in UTF-8 encoding to prevent character encoding issues?

To ensure that PHP files are saved in UTF-8 encoding and prevent character encoding issues, you can set the encoding in your text editor, configure your server to use UTF-8, and add a meta tag specifying UTF-8 in your HTML output. 

// Set UTF-8 encoding in PHP file
header('Content-Type: text/html; charset=utf-8');

// Set UTF-8 encoding in HTML output
echo '<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">';
