How Can I Efficiently Retrieve the Last Inserted ID in MySQL for Data Association?

Enhancing Data Association Using MySQL's Last Insert ID

To establish a link between images and user information across multiple tables, it is crucial to retrieve the last inserted row's ID in one table and utilize it for inserting data into another table. This query, however, cannot be executed using $image = $mysqli->insert_id, prompting the need for an alternative solution.

One efficient method involves setting up an auto-increment field for the ID column. This ensures that each row added to the table receives a unique identifier. Once this setup is complete, you can employ the following code:

$last_id = mysqli_insert_id($conn);

This command will retrieve the last inserted ID, which can then be used to associate the image with the corresponding user information in the other table. By leveraging this technique, you can establish effective data connections between multiple tables in your MySQL database.
