What best practices can be followed to ensure that PHP code is correctly parsed and displayed on a webpage without errors?

To ensure that PHP code is correctly parsed and displayed on a webpage without errors, it is important to follow best practices such as using proper syntax, avoiding deprecated functions, and properly handling errors. Additionally, it is recommended to enable error reporting and display errors only in development environments to prevent sensitive information from being exposed.

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Your PHP code here
?>
