What common issues can arise when using BBCode in PHP?

One common issue when using BBCode in PHP is that special characters within the BBCode tags can interfere with the parsing and rendering of the content. To solve this issue, you can use the htmlspecialchars function to escape these special characters before processing the BBCode. 

$bbcode = "[b]Hello, <script>alert('XSS');</script> World![/b]";
$bbcode = htmlspecialchars($bbcode);
echo $bbcode;
