How can one handle concurrent processes in MySQL when retrieving the last inserted ID for use in subsequent queries?

When dealing with concurrent processes in MySQL, it is important to ensure that the last inserted ID is retrieved correctly to avoid conflicts. One way to handle this is by using the LAST_INSERT_ID() function immediately after the INSERT query to get the ID and store it in a variable for later use in subsequent queries. 

// Insert query
mysqli_query($conn, "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')");

// Get the last inserted ID
$last_id = mysqli_insert_id($conn);

// Use the last inserted ID in subsequent queries
mysqli_query($conn, "SELECT * FROM table_name WHERE id = $last_id");
