Regular Expressions to remove Resource out of String

[JordashTalon]

I have a string like so:

/tutorialThumbs/image.png

How would I get

/tutorialThumbs/

and strip off anything that is like 'image.png or image.jpg etc..'

Thanks for any help

[logic_earth]

dirname()

[JordashTalon]

cool, that worked

Ok, now how would I get the image.png in a string?

example
/tutorialThumbs/image.png

into

image.png
?

Thanks

basename()

You could also use the pathinfo with the PATHINFO_* constants.
