I made this parser to solve my problem on a client website, so i decide to share it with you just if you found it here.
ADDING NEW BBCODE TAGS
To add new BBcode tags all you need is the tag name and some attributes to the tag, attributes inside the BBcode Object.
For example you wanted to add a tag call [website] which will change it content into clickable link of its website address, Simply add this to the tag object.
$patern="#\[website]([^\[]*)\[/website\]#i"; $replace='<a href="\\1" target="_blank" rel="nofollow">\\1</a>';
This is how to Implement that into this
