What are best practices for ensuring the correct retrieval of auto-incremented IDs in PHP MySQL queries?
When inserting a new record into a MySQL table with an auto-incremented ID column, it's important to retrieve the correct ID value generated by the database. One common way to do this in PHP is to use the `mysqli_insert_id()` function immediately after executing the INSERT query. This function returns the last auto-generated ID used in the most recent query, allowing you to store or use it as needed.
// Connect to the database
$connection = mysqli_connect("localhost", "username", "password", "database");
// Insert a new record into the table
mysqli_query($connection, "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')");
// Get the auto-incremented ID of the inserted record
$new_id = mysqli_insert_id($connection);
// Use the $new_id as needed
echo "The new record has ID: " . $new_id;
// Close the database connection
mysqli_close($connection);
