What is the importance of running PHP scripts through a web server for proper parsing?

When running PHP scripts, it is important to run them through a web server for proper parsing because the web server is responsible for interpreting the PHP code and executing it. Without a web server, the PHP code will not be parsed correctly and will not produce the desired output. Using a web server ensures that the PHP code is processed correctly and that the resulting web page is displayed as intended.

<?php
// This is a sample PHP script that should be run through a web server for proper parsing
echo "Hello, World!";
?>
