What steps can be taken to resolve unwanted line breaks in PHP-generated content?

Unwanted line breaks in PHP-generated content can be resolved by using the PHP function `ob_start()` to buffer the output and then `ob_get_clean()` to capture the content without any extra line breaks. This will ensure that the content is displayed without any additional line breaks being added.

<?php
ob_start();
// PHP-generated content with unwanted line breaks
$content = ob_get_clean();
echo $content;
?>
