[RESOLVED] Optional symbol in preg_match

[foxroberts]

Hi.

I am building a tiny CMS. I want the client to add pictures to a text easily without any HTML knowledge. The syntax should be like this:

(picture:filename.jpg, optional title)

Before the page is published, PHP replace the tags:
preg_replace('/(picture🙁.),(.))/Uis', '<img src="$1" title="$2" />');

If no comma is given, the replacement of course doesn't work. How can I tell replacement that comma and title are optional?

Thank you for any help!

Please don't hate me because of my bad pattern syntax...

preg_replace('/\(picture:(.*)(,(.*))?\)/Uis', '<img src="$1" title="$3" />');
