What are the limitations of printing variables directly from PHP in a web browser?

When printing variables directly from PHP in a web browser, the output may not always be formatted correctly or may not be easily readable for debugging purposes. To solve this issue, you can use the `var_dump()` function in PHP to display the data type and value of a variable in a more structured and informative way. 

<?php
$variable = "Hello, World!";
var_dump($variable);
?>
