What are the common pitfalls when using last insert ID in PHP for database operations?

Common pitfalls when using last insert ID in PHP for database operations include not checking if the query was successful before retrieving the last insert ID, using the wrong connection object to retrieve the ID, and not handling concurrent database operations that might affect the last insert ID value. To solve these issues, always check if the query was successful before retrieving the last insert ID, ensure you are using the correct connection object to retrieve the ID, and consider using transactions to handle concurrent database operations. 

// Perform the database operation
$query = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";
$result = mysqli_query($connection, $query);

// Check if the query was successful
if ($result) {
    // Retrieve the last insert ID
    $last_id = mysqli_insert_id($connection);
    echo "Last Insert ID: " . $last_id;
} else {
    echo "Error: " . mysqli_error($connection);
}
