What resources or documentation should be referenced when dealing with auto_incremented IDs in PHP and MySQL?

When dealing with auto_incremented IDs in PHP and MySQL, it is important to ensure that the primary key column in your database table is set to auto_increment. This allows MySQL to automatically generate a unique ID for each new record. When inserting data into the table, you should exclude the auto_incremented ID column from your INSERT query to let MySQL handle its generation.

// Connect to MySQL database
$connection = new mysqli('localhost', 'username', 'password', 'database');

// Insert data into table, excluding the auto_incremented ID column
$query = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";
$connection->query($query);

// Get the auto-generated ID of the last inserted record
$new_id = $connection->insert_id;

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