Introduction

Python and PHP are the most popular and widely used programming languages, each having its own unique strengths for various applications. Python is known for its simplicity and versatility and is used in data science, web development, and automation tasks. On the other hand, PHP remains a powerful tool for server-side scripting and dynamic web content creation.

In this article, we will guide you through the installation processes for both Python and PHP on your system. We will also show you how to verify their installations by checking their versions, ensuring that your development environment is set up correctly. Whether you are setting up a new development machine or just confirming that your existing setup is up to date, this guide will provide clear, step-by-step instructions to get you started with these essential programming languages.

Python

Python is a user-friendly programming language known for its clear and readable syntax. Python uses indentation to define the structure rather than braces in other programming languages. This makes it easy for beginners as well as experienced developers to tackle various projects. It supports a wide range of applications like data analysis, artificial intelligence, and machine learning. It has a rich ecosystem of libraries.

Prerequisites:

• Python supports Windows 7 and later versions.
• Choose an appropriate installer depending on your system architecture (32-bit or 64-bit) from the Python website.
• You need administrative privileges to install it and modify system PATH variables.

Step-by-Step Guide

1. Go to www.python.org, select Downloads, and click on Download Python 3.12.5.

2. Click on Open File under Downloads in the top-right corner of the window.

3. Firstly,

• Check the box next to Use admin privileges when installing py.exe
• Check the box next to Add python.exe to PATH

Secondly, click on Customize Installation (choose location and features).

4. Under Optional Features, check all the boxes and click on Next.

5. Under Advanced Options,

• Check the box next to Install Python 3.12 for all users.
• You can change the location of the file you want to install by clicking on Browse.
• Click on Install.

6. Once the installation is successful, you can see the screen below.

Click on Close.

7. Verify the installation of Python by running the below command

Command: python --version

It will show you the Python version installed. Here, Python 3.12.5 is installed.

8. Now, to run a Python program, use the command shell. So, to do that, start by running the command below.

Command: python

Now, you are in a python shell.

Examples:

• Try to enter some information in the print command or arithmetic operation, and the message will be displayed on the screen.

Command: print(“welcome!”)
Output: welcome!

• Give some arithmetic operation

Command: 2+3
Output: 5

9. Run a Python program using IDLE. Go to the Windows search bar and type IDLE. The Python command prompt will open.

10. Here, in IDLE Shell also, you can run Python programs.

• Go to File > New File.

• Now, save the file by clicking on Save As. You can browse by selecting the path where you want to save the file.

Note: Here, the file is saved as ‘hi’. It will take ‘py’ as an extension.

• Now, write a program

Example: print (“hello, welcome”)

• Run the program by clicking on the Run Module.

• The screen below shows the message.

Hypertext Preprocessor (PHP)

PHP (Hypertext Preprocessor) is a widely used server-side scripting language designed for web development. It can be embedded directly into web pages, making it easy to integrate dynamic content with static web pages. PHP is commonly used with MySQL and PostgreSQL to create data-driven websites and applications, It can be run on various operating systems like Windows, Linux, and macOS and supports web servers such as Apache and Nginx.

Prerequisites:

• Python supports Windows 7 and later versions.
• Choose an appropriate installer depending on your system architecture (32-bit or 64-bit) from the Python website.
• Having a text editor (like Notepad++, VS Code, or Sublime Text) or an Integrated Development Environment (IDE) will help you write and manage PHP code.
• Database servers, such as MySQL or MariaDB, are needed to handle data storage and management.
• You need administrative privileges to install it and modify system PATH variables.

Step-by-Step Guide

1. Go to www.php.net/downloads.php and click on Windows downloads.

2. A new page opens,

• Under VS16 x64 Thread Safe (2024-Jul-30 18:09:04), click on Zip [30.81MB].

3. Click on Open File under Downloads in the top-right corner.

4. It will navigate to the Downloads section in File Explorer. As it is a zip folder, click on Extract All.

5. If you want to change the destination of the file, click on Browse. Otherwise, leave it as it is.

• Click on Extract.

6. Now, you can see all the files have been extracted.

7. Now, add this PHP path to the environment variables.

• Go to the Windows search bar and type Environment Variables. Select Edit the system environment variables.

8. In the System Properties window, click on Environment Variables.

9. Under System Variables, double-click on Path.

10. A new window opens.

• In the Edit environment variable window, click on New, copy the path, and click OK.

• Click OK in the Environment Variables window.
• Click OK in the System Properties window.

11. Now, type the command prompt in the Windows search bar. Select Command Prompt.

12.  Check the version of PHP by running the below command.

Command: php -v (or) php --version

13.  How to create a file with PHP

• Create a folder on the desktop and name it.

Note: As an example, a folder is created as a PHP folder.

• Double-click on the folder.

14.  In the php folder, create a text document.

• Right-click on the empty space.
• Select New, and select Text Document.

15.  Name the file as filename.php (php is the extension of the file).

• If you cannot name the file with php as its extension, then
• Click on View in the menu bar.

• Check the box next to File name extensions.
• Now, you should be able to add PHP as an extension.

Note: Here, as an example, demo.php is created.

FAQs

Q1. What type of language is Python?

Answer: Python is an interpreted, interactive, object-oriented programming language. It incorporates modules, exceptions, dynamic typing, very high-level dynamic data types, and classes. It supports multiple programming paradigms beyond object-oriented programming, such as procedural and functional programming

Q2. What are the uses of PHP?

Answer:

• It is a server-side scripting language used to design dynamic websites or web applications.
• It receives data from forms to generate dynamic page content.
• It can work with databases and sessions, send and receive cookies, send emails, etc.
• It can be used to add, delete, or modify content within the database.
• It can be used to set a restriction on the user’s access to the web page.

Q3. Does PHP need a compiler?

Answer: If your server supports PHP, then you do not need to do anything. Just create your PHP files, put them in your web directory and the server will automatically parse them for you. There is no need to compile anything, nor do you need to install any extra tools.

Q4. What are the data types in Python?

Answer: Python has six standard data types. Data types are the classification of data items and represent the kind of value that shows what operations can be performed on a particular data set. Because everything is an object in Python, they are classes. Variables are instances of the classes.

The data types in Python are numbers, strings, lists, tuples, sets, and dictionaries.

Q5. Is PHP a case-sensitive language?

Answer: Not fully. PHP is partly a case-sensitive language, where the variable names are case-sensitive but the function names are not. Also, user-defined functions aren’t case-sensitive, but the rest of the language is.

Q6. What is a Python virtual environment?

Answer: A Python virtual environment is an isolated environment that allows you to manage dependencies and packages for a specific project without affecting the global Python installation. It can be created using tools like Venv or Virtualenv.
