PHP Install

Do you need to install anything?

Not always. Many web hosting providers already have PHP installed and configured, so if you simply upload a .php file to a host that supports PHP, it will run without any setup on your part. You only need a local installation when you want to build and test PHP applications on your own computer before publishing them. Once installed, you are ready for the PHP Syntax lesson.

• A web server such as Apache or Nginx to receive requests and serve pages
• The PHP interpreter, which actually executes your PHP code
• Optionally a database such as MySQL or MariaDB if your app stores data

The easy way: an all-in-one stack

For beginners, the simplest approach is to install a bundled package that includes the web server, PHP, and a database together, already configured to work as a unit. These stacks let you skip the tricky manual configuration and start writing code within minutes.

Running PHP without a full server

PHP ships with a small built-in web server that is perfect for learning and quick experiments. Once PHP is installed and available on your command line, you can serve the files in a folder with a single command. This avoids installing Apache or Nginx just to try things out.

# Move into your project folder, then start the server
php -S localhost:8000

# Now open http://localhost:8000 in your browser

You can also run a PHP script directly from the command line without any browser at all. This is useful for testing small snippets or writing scripts that are not meant to be web pages.

<?php
// Save this as hello.php
echo "PHP is installed and working!\n";
echo "Running version: " . phpversion();
?>

# Run the script from your terminal
php hello.php

# Check which version of PHP you have
php -v
