How can debugging tools like the MySQL console or phpMyAdmin be used to troubleshoot issues with retrieving values from a MySQL procedure in PHP?

When troubleshooting issues with retrieving values from a MySQL procedure in PHP, you can use debugging tools like the MySQL console or phpMyAdmin to check the output of the procedure and ensure it is returning the expected results. By inspecting the data returned by the procedure, you can identify any errors in the SQL query or the procedure itself that may be causing issues with retrieving values in your PHP code. 

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

// Call the MySQL procedure
$result = $mysqli->query("CALL your_procedure()");

// Check if the procedure call was successful
if($result){
    // Fetch the result set
    while($row = $result->fetch_assoc()){
        // Process the retrieved values
        echo $row['column_name'] . "<br>";
    }
} else {
    // Display an error message if the procedure call failed
    echo "Error: " . $mysqli->error;
}

// Close the database connection
$mysqli->close();
