How can HTML interpretation affect the output of sprintf in PHP?

When HTML tags are included in the input string passed to `sprintf` in PHP, they can interfere with the placeholders used by `sprintf`, causing unexpected output or errors. To prevent this issue, you can escape the input string using `htmlspecialchars` before passing it to `sprintf`. This will ensure that any HTML tags are properly encoded and will not interfere with the placeholder formatting. 

$input = "<b>Hello</b>";
$escaped_input = htmlspecialchars($input, ENT_QUOTES, 'UTF-8');
$output = sprintf("Formatted string with input: %s", $escaped_input);
echo $output;
