What steps can be taken to troubleshoot and debug errors related to mysqli functions in PHP code?

To troubleshoot and debug errors related to mysqli functions in PHP code, you can start by checking for syntax errors, ensuring that the database connection is established correctly, and verifying that the SQL queries are valid. Additionally, you can use error handling techniques such as mysqli_error() or mysqli_stmt_error() to get more information about the error. 

// Example code snippet to troubleshoot mysqli errors
$conn = mysqli_connect("localhost", "username", "password", "database");

if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}

$sql = "SELECT * FROM table";
$result = mysqli_query($conn, $sql);

if (!$result) {
    die("Error in SQL query: " . mysqli_error($conn));
}

// Continue with processing the query results
