2. Create a PHP page

After establishing the database, we need to create a PHP page to implement the simulated bank deposit and withdrawal function. We can implement it in an object-oriented way, specifically in the following steps.

(1) Connect to the database: First, we need to connect to the database and use the PDO class provided by PHP to connect to the database.

(2) Create a bank account class: We need to define a bank account class. This class contains the following methods:

--Query account balance

--Deposit

--Withdrawal

(4) Front-end display: Finally, we need to use HTML and CSS on the PHP page to present the effect of the bank page. Users can perform operations such as depositing and withdrawing money on the page.

3. Testing and Optimization

After creating the PHP page, we need to test and optimize it. Testing for any bugs, and optimization to see how to make our banking simulation system more efficient, secure, and easier to use.

Summary

With the rise of digital banking, PHP, as an important part of banking business, will play an increasingly important role.
