What are the different methods to retrieve the ID of the last entry in a MySQL table using PHP?

To retrieve the ID of the last entry in a MySQL table using PHP, you can use the `mysqli_insert_id()` function which returns the auto-generated ID used in the last query. This function can be called immediately after an INSERT query to get the ID of the last inserted row. 

// Connect to the database
$conn = mysqli_connect("localhost", "username", "password", "database");

// Insert new data into the table
mysqli_query($conn, "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')");

// Get the ID of the last inserted row
$last_id = mysqli_insert_id($conn);

// Output the last inserted ID
echo "The ID of the last entry is: " . $last_id;
