Parsing multiple lists in bbcode?

Question

Hi everyone I have a very simple bbcode parsing system, it currently has problems with lists in lists.

My code is:

$find = array( '/\[list\](.*?)\[\/list\]/is', '/\[\*\](.*?)(\n|\r\n?)/is', '/\[ul\](.*?)\[\/ul\]/is', '/\[li\](.*?)\[\/li\]/is' ); $replace = array( '<ul>$1</ul>', '<li>$1</li>', '<ul>$1</ul>', '<li>$1</li>' ); $body = preg_replace($find, $replace, $body); 

The problem is that you have another list inside the li tags, after which it is not completely parsed, the screenshot shows:

Here's how it should look:

I know that my code is probably too simple for him, but how to configure it so that it can parse a list in a list item?

Instead of using regular expressions, you have several options.

• Use PHP Extension BBCode Parsing
• Make a much simpler replacement, i.e. directly replace [ul] with <ul> etc.

I'm not saying that this cannot be done with Regex, it’s just not the easiest option.

Regex based replacement is used here:

 $body = '[ul][li]test[/li][li]test[/li][li]test[ul][li]lol[/li][/ul][/li][li]hehe[/li][/ul]'; $find = array( '/\[(\/?)list\]/i', '/\[\*\](.*?)(\n|\r\n?)/i', '/\[(\/?)ul\]/i', '/\[(\/?)li\]/i' ); $replace = array( '<$1ul>', '<li>$1</li>', '<$1ul>', '<$1li>' ); $body = preg_replace($find, $replace, $body);
