Answer 1

I'm not quite sure what the problem is (do you have only 1 row instead of desired number of rows?)
Shows all rows from received data:
for (NSDictionary *item in array) {
firstname.text=[item objectForKey:#"firstName"];
lastname.text=[item objectForKey:#"lastname"];
phone.text=[item objectForKey:#"phone"];
}

Answer 2

The output you got for server is a dictionary and the parent key is "Key". To get array index dynamically please see the code below
NSMutableArray *infoArray=[[NSMutableArray alloc]init];
infoArray =[jsonArray objectForKey:#"Key"]; // this is your array with all information stored index wise.
NSLog(#"%#", infoArray);
for(int i=0; i<infoArray.count; i++)
{
NSLog(#"%#", [[infoArray objectAtIndex:i]objectForKey:#"firstname"]);
NSLog(#"%#", [[infoArray objectAtIndex:i]objectForKey:#"lastnamename"]);
}
or
The issue is with PHP side ask them to replace "[" and "]" with "(" and ")".
Hope this will help
