I need help to understand JSON Elements (Response Messages) from this function - php

Question

I am working on a project that previously done with another developer. This project based on PHP Yii framework and mobile side is Android to get JSON messages from the web services that provided in the website.
I'm stuck in this web service function "getStamp"
I don't know what are the JSON response messages. I mean what are the string Values that I'll hold for 'stampID', 'stampName', 'stampImg'.
These are the information that I have:
request parameters:
kioskid
accesstoken
tagid
eventid
checking = 0 or 1
for failed response:
status = 0
message = error message
for success response:
status = 1
tappedStamp = the obtain stamp ID after tapping the device (if checking not equal to 1)
message = the message of the obtained stamp (if checking not equal to 1)
collectedStamp = list of collected stamp ID
If you want to use 'getStamp' web service to do the checking on how
many stamps that have been collected by the user, then you pass
'checking' as 1. If you want to use that web service to collect the
stamp of the kiosk, then you pass 'checking' as 0.
So far as what I understand from the Code and explanation that 'collectedStamp' and 'tappedStamp' are JSON Object names of a JSON Arrays
I need to know these 3 Elements (I suppose to get it from some where the names are random not real I just make it to explain to you what need)
'stampID', 'stampName','stampImg'
{ "collectedStamp" : [ { "stampID" : "1",
"stampName" : "stamp1",
"stampImg": "stamp1.png"
},
{ "stampID" : "2",
"stampName" : "stamp2",
"stampImg": "stamp2.png"
},
],
"status" : "1"
}
{ "tappedStamp" : [ { "stampID" : "1",
"stampName" : "stamp1",
"stampImg": "stamp1.png"
},
{ "stampID" : "2",
"stampName" : "stamp2",
"stampImg": "stamp2.png"
},
],
"status" : "1"
}
For Android Implementation most likely I'll use the same code that I provided in this post
Errors when getting JSON result into ListView
if you see in the web service function in that link you'll find this
$list = array();
foreach($events as $row){
$list[] = array('id'=>$row->id, 'name'=>$row->eventname);
}
$response['status'] = '1';
$response['list'] = $list;
}
which means that that the JSON response['list'] Contains 'id' and 'name' objects
and these are the String values that I add it inside ListView Adapter
I need to know the equivalent to 'id' and 'name' in this web Service

}
}
}
}
}
}
$this->_sendResponse(200, CJSON::encode($response));
} else {
$this->_sendResponse(400);
}
}
One more question:
How can I check the web service from the Browser and pass the parameter (this Project uses Yii Framework)? So I can get JSON message either from browser.
Update:
After using "POSTMAN REST Client" I got this message
if checking = 1
{"status":"1","collectedStamp":[]}
if checking = 0
this is the HTML Code I got
