What are common BBCode functions used in PHP forums and how can they be converted to HTML?

Common BBCode functions used in PHP forums include [b] for bold text, [i] for italic text, [url] for creating a hyperlink, and [img] for inserting images. These BBCode functions can be converted to HTML by using PHP's str_replace function to replace the BBCode tags with their corresponding HTML tags. 

// Sample PHP code snippet to convert BBCode to HTML
$bbcode = "[b]This is bold text[/b] [i]and this is italic text[/i] [url=https://www.example.com]Click here[/url] [img]https://www.example.com/image.jpg[/img]";

$html = str_replace(['[b]', '[/b]', '[i]', '[/i]', '[url=', '[/url]', '[img]', '[/img]'], ['<b>', '</b>', '<i>', '</i>', '<a href=', '</a>', '<img src=', '</img>'], $bbcode);

echo $html;
