php - parse EXIF data?

Question

I get the EXIF data of images

'ExposureTime' => string '10/150' (length=6)
'FNumber' => string '35/10' (length=5)
'ISOSpeedRatings' => int 100
'FocalLength' => string '180/10' (length=6)

What should i do to it look like below

Focal Length  18mm
Exposure Time 1/15 sec
ISO- Speed ISO-100
F-Number = F/3.5

So is there a library php allow me read and parse data to look like when i view image's properties ? or some rules for me calculate base on it
