What is PHP?

• PHP stands for Hypertext Preprocessor.
• It is a server-side scripting language used for:
  • Creating dynamic websites
  • Handling forms
  • Working with databases (like MySQL)
  • Building web applications
• PHP code is executed on the server, and the result (HTML) is sent to the browser.

Example:

<?php
echo "Hello, World!";
?>

• Here, <?php ... ?> is used to write PHP code.
• echo is used to output text to the browser.
