How can developers ensure proper HTML syntax when echoing line breaks in PHP output?

When echoing line breaks in PHP output, developers should use the PHP `nl2br()` function to convert newline characters to HTML line breaks. This ensures that the line breaks are properly rendered in the HTML output and maintains proper HTML syntax. 

<?php
$text = "This is a line with\na line break.";
echo nl2br($text);
?>
