What is the correct way to prevent HTML output in PHP instead of using "echo '';?

To prevent HTML output in PHP without using "echo '';", you can use the PHP output buffering functions ob_start() and ob_end_clean(). This allows you to capture the output generated by PHP code without sending it to the browser. By using ob_start() at the beginning of your script and ob_end_clean() at the end, you can prevent any unintended HTML output. 

<?php
ob_start();

// Your PHP code here

ob_end_clean();
?>
