Question One

Question: When building a modern e-portal, developers rarely use PHP alone; they almost always bring JavaScript into the mix. From a users perspective, why is this combination so important? Describe how JavaScript “fills the gaps” that a server-side language like PHP leaves behind when trying to create a smooth, interactive experience.

Question Two

Question: Imagine you are building a security feature for a website and you need to know exactly where a visitor is coming from or what kind of browser they are using. PHP provides a special tool called $_SERVER for this. Explain how this variable “listens” to the incoming request and list three specific pieces of information it can tell a developer about the user or the server setup.

Question Three

Question: In PHP, we have both “Variables” and “Constants” to store data, but we use them for very different reasons. If you were setting up a configuration file for a large website, why might you choose a Constant for the sites database password but a Variable for a users shopping cart total? Explain the difference in how they are handled by the system after they are created.

Question Four

Question: Create a simple, user-friendly PHP application that acts as a “Currency Converter.” The program should:

1. Display an HTML form where a user can enter an amount in USD.

Note : Once submitted, the script should multiply that amount by a fixed exchange rate (e.g., 3.75 for SAR).

2. Display a clear message back to the user, such as: “The equivalent of $100 USD is 375 SAR.”

(Include both the HTML form and the PHP logic in your answer.)
