How can PHP scripts be structured to prevent tabulators from being included in the response?

To prevent tabulators from being included in the response, you can use the PHP output buffering functions to capture the output and then sanitize it before sending it to the client. This can be done by replacing tab characters with spaces or by using the `trim()` function to remove any leading or trailing whitespace.

ob_start();

// Your PHP code here

$output = ob_get_clean();
$output = str_replace("\t", " ", $output);

echo $output;
