What are some common challenges when outputting CSS instructions using PHP echo?

One common challenge when outputting CSS instructions using PHP echo is properly escaping characters to avoid syntax errors. To solve this issue, you can use the PHP htmlentities function to encode special characters in the CSS code before echoing it out. 

<?php
$cssCode = "body { background-color: #fff; }";
echo "<style>";
echo htmlentities($cssCode);
echo "</style>";
?>
