What steps can be taken to prevent a PHP script run via CLI from returning a blank line?

To prevent a PHP script run via CLI from returning a blank line, you can ensure that the script does not have any unnecessary whitespace or echo statements that could inadvertently output a blank line. Additionally, you can use the `exit` function to terminate the script after all desired output has been generated. 

<?php

// Your PHP script code here

// Make sure there are no unnecessary whitespace or echo statements that could output a blank line

// Terminate the script after all desired output has been generated
exit;
