How can PHP developers troubleshoot and resolve encoding issues when working with UTF-8 data in PHP and MySQL?

When working with UTF-8 data in PHP and MySQL, developers can troubleshoot and resolve encoding issues by ensuring that the connection between PHP and MySQL is set to UTF-8, specifying the character set in MySQL queries, and using functions like utf8_encode() and utf8_decode() to handle encoding and decoding of strings. 

// Set the connection character set to UTF-8
mysqli_set_charset($connection, "utf8");

// Specify the character set in MySQL queries
$query = "SELECT * FROM table_name WHERE column_name = 'value' COLLATE utf8_general_ci";

// Use utf8_encode() and utf8_decode() to handle encoding and decoding
$encoded_string = utf8_encode($string);
$decoded_string = utf8_decode($encoded_string);
