PHP

Write a  PHP function that adds a transaction.  

```php function addTransaction($form){ // INSERT INTO, using bindParam to add items from $form array // $form['amount'], $form['message'], $form['subject'] etc. } ``` ### Explanation: This code snippet is a part of a PHP function named `addTransaction`. The function is designed to handle transactions by utilizing a PHP data array called `$form`. The comments within the function provide clues about its intended purpose: - **INSERT INTO**: Indicates that the function probably interacts with a database. The `INSERT INTO` statement is commonly used in SQL to add new rows to a table. - **using bindParam**: Suggests the function uses prepared statements with `bindParam` to securely insert data from the `$form` array into a database. This approach helps prevent SQL injection attacks by sanitizing input data. - **$form['amount'], $form['message'], $form['subject'] etc.**: These references are placeholders for the actual data fields present in the `$form` array. They imply that these fields (amount, message, subject, and possibly others) are expected to be part of the data structure being processed. This code is typical in web applications that manage data inputs, ensuring that the information is securely and efficiently stored in a database.
