Question

PHP

Using PHP write a function that does the query to select all transactions order by date desc.  

```javascript function findAllTransactions() { // write the code here that does the query to select all transactions order by date desc } ``` ### Explanation This is a JavaScript function named `findAllTransactions`. It is intended to execute a database query that retrieves all transaction records, ordered by date in descending order. The function body currently contains a comment indicating where to write the query logic. To implement this function, one would typically use a database query language such as SQL. For example, if you were using SQL, a possible implementation might involve a query like: ```sql SELECT * FROM transactions ORDER BY date DESC; ``` This query would select all entries from a table named `transactions`, sorting them so that the most recent transaction appears first. ### Application - **Educational Context**: This function is useful for teaching how to interact with databases using JavaScript, particularly in Node.js environments where database operations are common. - **Practical Example**: In a financial application, this function could be used to display user transaction histories, showing the most recent transactions at the top.
