What are common issues with character encoding in PHP when working with HTML and MySQL?

Common issues with character encoding in PHP when working with HTML and MySQL include displaying special characters incorrectly, such as accented letters or symbols, due to mismatched character sets between the database, PHP, and HTML. To solve this, ensure that all components are using the same character encoding, typically UTF-8, and set the appropriate charset in the HTML header. 

// Set the character encoding for PHP
header('Content-Type: text/html; charset=utf-8');

// Set the character encoding for MySQL connection
$mysqli->set_charset("utf8");

// Set the character encoding for HTML
<meta charset="utf-8">
