What are the advantages of using BB code in forms for user input compared to allowing raw HTML?

Using BB code in forms for user input is advantageous compared to allowing raw HTML because it provides a more controlled and secure way for users to format their input without the risk of injecting malicious scripts. BB code allows users to easily format their text using simple tags, while raw HTML can be complex and prone to errors. Additionally, BB code can be easily converted into HTML before displaying it on the website. 

// Example of converting BB code to HTML in PHP
$bbcode = "[b]Hello World[/b]";
$html = preg_replace(
    array('/\[b\](.*?)\[\/b\]/', '/\[i\](.*?)\[\/i\]/', '/\[u\](.*?)\[\/u\]/'),
    array('<b>$1</b>', '<i>$1</i>', '<u>$1</u>'),
    $bbcode
);
echo $html; // Output: <b>Hello World</b>
