How can error handling techniques, such as displaying error messages or terminating scripts, help in debugging PHP code that interacts with a MySQL database?

Error handling techniques, such as displaying error messages or terminating scripts, can help in debugging PHP code that interacts with a MySQL database by providing valuable information about what went wrong during the execution of the script. Displaying error messages can help identify the specific issue, such as a syntax error or a connection problem, while terminating scripts can prevent further execution when an error occurs, allowing for quicker identification and resolution of the problem. 

// Set up error handling for MySQL connection
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Check for connection errors
if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}
