What is the significance of using LAST_INSERT_ID() function in PHP with MySQL?

When inserting a new row into a MySQL database table using PHP, it is important to retrieve the auto-generated ID of the last inserted row. This can be done using the LAST_INSERT_ID() function in MySQL. This ID can then be used for further operations or stored in a variable for future reference. 

// Insert a new row into a table
$query = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";
$result = mysqli_query($connection, $query);

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

// Use the last ID for further operations
echo "Last inserted ID: " . $last_id;
