How Can I Verify Successful Database Inserts Using PHP\'s PDO?

Using PDO to Verify Successful Database Inserts

To ensure the successful execution of a database insert query when using PHP's PDO extension, it is essential to understand if the operation was completed without any errors.

Using PDO's execute() method, you can insert records into a MySQL database. However, to determine the outcome of the operation, you can utilize two methods:

1. Checking the Return Value of execute():

The execute() method of the PDOStatement object returns a boolean value. A true value indicates successful execution, while a false value suggests an error occurred during the operation. To check for success, you can use the following code:

if ($stmt->execute()) {
  // Insert successful
} else {
  // Insert failed
}

2. Using errorCode() to Retrieve Error Codes:

The errorCode() method of the PDOStatement object returns an error code if an error occurred during the execution of the query. If the code is not equal to '00000', it indicates an error has occurred. You can check for errors using the following code:

if ($stmt->errorCode() !== '00000') {
  // Error occurred
} else {
  // Insert successful
}

By utilizing these methods, you can programmatically determine if a database insert operation has been executed successfully, allowing you to handle error conditions as needed.
