Question

In a system that I’m developing I need to recognize the youtube link in the following format

[youtube]youtube url[/youtube]

for the moment I arrived at this regular expression:

#\[youtube\]http://www.youtube\.(.*)/watch\?v=([a-zA-Z0-9_-]*)\[\/youtube\]#s

But this pattern isn’t able to recognize url like

[youtube]http://www.youtube.com/watch?v=s3wXkv1VW54&feature=fvst%5B/youtube%5D

Note the feature=fvst.

Some one can help me in recognize all possible youtube url?

Answer 1

How about

|\[youtube\]http://www.youtube\.(.*?)/watch\?v=([a-zA-Z0-9_-]*)[%&=#a-zA-Z0-9_-]*\[\/youtube\]|s

EDIT: Changed the regex to keep only the video id inside parentheses.
