What is the recommended way to force a line break in PHP when generating HTML content?

When generating HTML content in PHP, the recommended way to force a line break is to use the `<br>` tag. This tag creates a line break in the rendered HTML output, allowing for better formatting and readability of the content. To implement a line break in PHP, simply concatenate the `<br>` tag to the end of the string where the line break is desired.

echo "This is a line of text.<br>";
echo "This is another line of text.";
