PHP server side scripting

PHP server side scripting
	Chapter 4. Add SW to Raspberry PI OS

To get php (server side scripts) for apache sudo apt install php libapache2-mod-php -y

Create a test php script

cd /var/www/html

sudo touch php.php

sudo mc and add

<html>
  <body>
    <?php 
      phpinfo(); 
    ?>
  </body>
</html>

As whoami shows PHP script run as user www-data.

PHP has just the rights of the user www-data and might not run system commands commands

There are very good reason why this is like that.

It is more secure to run a cron service and write data to the disk (ram disk /run if it changes frequently) then have php directly get the data.
