To integrate PHP with Raspberry Pi, you can follow the steps below:

1. Install Apache web server:
– Open the terminal on your Raspberry Pi.
– Run the following command to install Apache: `sudo apt-get install apache2`
– Start the Apache server: `sudo systemctl start apache2`
– Verify that Apache is running by opening a web browser and entering your Raspberry Pi’s IP address. You should see the default Apache page.

2. Install PHP:
– Install PHP with the following command: `sudo apt-get install php`

3. Test PHP installation:
– In the terminal, navigate to the Apache web server’s root directory: `cd /var/www/html`.
– Create a test PHP file: `sudo nano test.php`.
– Add the following code to the file:
“`php

“`
– Save and exit the file.
– Open a web browser and enter your Raspberry Pi’s IP address followed by `/test.php`. You should see the PHP information page.

4. Write PHP code:
– Create a new PHP file in the `/var/www/html` directory using a text editor of your choice.
– Write your PHP code in the file and save it.

5. Access PHP page:
– Open a web browser and enter your Raspberry Pi’s IP address followed by the filename of your PHP file. You should see the output of your PHP code.

You can now integrate PHP with Raspberry Pi and use it to create dynamic web applications or interact with the hardware on your Pi.
