  To obtain the last insert ID in PHP when working with cryptocurrency transactions, you can use the mysqli_insert_id() function. This function returns the ID generated by the previous INSERT query. Make sure to use the mysqli extension and establish a connection to your database before executing the query. Here's an example: ```php <?php $conn = mysqli_connect('localhost', 'username', 'password', 'database'); $query = "INSERT INTO transactions (amount, currency) VALUES (100, 'Bitcoin')"; mysqli_query($conn, $query); $lastInsertID = mysqli_insert_id($conn); echo $lastInsertID; ?> ``` This will output the last insert ID generated by the query.

  When working with cryptocurrency transactions in PHP, another approach to obtain the last insert ID is by using the PDO extension. PDO provides a method called lastInsertId() which returns the ID of the last inserted row. Here's an example: ```php <?php $dsn = 'mysql:host=localhost;dbname=database'; $user = 'username'; $password = 'password'; $pdo = new PDO($dsn, $user, $password); $query = "INSERT INTO transactions (amount, currency) VALUES (100, 'Bitcoin')"; $pdo->exec($query); $lastInsertID = $pdo->lastInsertId(); echo $lastInsertID; ?> ``` This will also output the last insert ID generated by the query.

  When it comes to obtaining the last insert ID in PHP for cryptocurrency transactions, it's important to ensure the security and integrity of your database. One best practice is to use prepared statements to prevent SQL injection attacks. Prepared statements can also help improve performance by reusing the prepared query. Additionally, consider implementing proper error handling to catch any database-related errors that may occur during the transaction process. By following these best practices, you can safely and efficiently obtain the last insert ID in PHP when working with cryptocurrency transactions.
