How can PHP and MySQL knowledge be improved to troubleshoot and resolve character encoding problems effectively?

Character encoding problems in PHP and MySQL can be resolved effectively by ensuring that both systems are using the same character encoding, such as UTF-8. This can be achieved by setting the character set in MySQL connection and using appropriate encoding functions in PHP to handle input and output data. 

// Set character encoding in MySQL connection
$mysqli = new mysqli("localhost", "username", "password", "database");
$mysqli->set_charset("utf8");

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