How can PHP code be properly structured to avoid parsing errors and unexpected behavior?

To avoid parsing errors and unexpected behavior in PHP code, it is important to follow proper coding conventions such as using consistent indentation, clear variable names, and commenting code where necessary. Additionally, make sure to properly close all parentheses, brackets, and quotes to avoid syntax errors. Example:

<?php

// Correctly structured PHP code to avoid parsing errors and unexpected behavior
$variable = "Hello, World!";
echo $variable;

?>
