Problem with Server side php script to recieve json messages

[rager]

I am having a problem in receiving data in php in json format

I have a client page which will send a json request with the following headers

Content-type : application/json

Accept : text/plain

The Json message contains the following fields

'photo' : a jpeg image (binary)

'title' : title of the photo (text)

'comment' : comments on the photo (text)

 

can someone enlighten me on how do I write a simple server-side script in php to decode the Json file and just save the photo and print out the title and comment?
