How can PHP developers address the issue of empty strings or unexpected characters when using htmlentities() in PHP?

When using htmlentities() in PHP, empty strings or unexpected characters can cause issues such as returning an empty string or not properly encoding special characters. To address this, developers can use the htmlspecialchars() function instead, which handles empty strings and unexpected characters more effectively. 

// Using htmlspecialchars() instead of htmlentities() to handle empty strings and unexpected characters
$unsafe_string = ''; // Empty string or unexpected characters
$safe_string = htmlspecialchars($unsafe_string, ENT_QUOTES, 'UTF-8');
echo $safe_string;
