What is the difference between server-side and client-side execution in PHP?

Server-side execution refers to running PHP code on the server before sending the processed output to the client's browser. Client-side execution, on the other hand, involves running PHP code directly in the browser using JavaScript or AJAX. Server-side execution is more secure as it prevents clients from accessing sensitive information or manipulating the code, while client-side execution can enhance user experience by reducing server load and improving responsiveness. 

// Server-side execution example
<?php
  $name = "John";
  echo "Hello, $name!";
?>
