What role does the character set and collation of a MySQL database table play in ensuring the proper storage and retrieval of special characters when using PHP?

The character set and collation of a MySQL database table play a crucial role in ensuring the proper storage and retrieval of special characters when using PHP. By setting the character set to UTF-8 and the collation to utf8_general_ci, you can handle a wide range of special characters without any issues. 

// Set the character set and collation for the database connection
$mysqli = new mysqli("localhost", "username", "password", "database");
$mysqli->set_charset("utf8");

// Set the character set and collation for the current session
$mysqli->query("SET NAMES 'utf8'");
$mysqli->query("SET CHARACTER SET 'utf8'");
$mysqli->query("SET character_set_connection = 'utf8'");
