Are there any common pitfalls to avoid when converting bbcode in PHP, as seen in the provided code snippet?

One common pitfall to avoid when converting bbcode in PHP is not properly escaping special characters in the input string. This can lead to security vulnerabilities such as cross-site scripting (XSS) attacks. To solve this issue, it is important to use functions like htmlspecialchars() to escape special characters before outputting the converted bbcode. 

// Example code snippet with proper escaping of special characters
$input = "[b]Hello, <script>alert('XSS');</script> World![/b]";
$bbcode = htmlspecialchars($input);

echo $bbcode;
