As mapek already posted code for PHP , let me post answers for iOS part only. You can pass the parametres in POST like below.

Method: 1

NSData*  submitData    = [[NSString stringWithFormat:@"dishname=%@&description=%@",textfieldOne.text, textfieldTwo.text] dataUsingEncoding:NSUTF8StringEncoding];
       NSMutableURLRequest *submitrequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.example.com/phpfile.php"]];
    NSString *request = [[NSString alloc]initWithData:submitData encoding:NSUTF8StringEncoding];
    NSLog(@"request is %@",request);
    [submitrequest setHTTPMethod:@"POST"];
    [submitrequest setHTTPBody:submitData];
 [NSURLConnection sendAsynchronousRequest:submitrequest
                                   queue:[NSOperationQueue mainQueue]
                       completionHandler:^(NSURLResponse *response, NSData *data, NSError *error)
  {
  NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
  NSLog(@"jsonString values=%@",jsonString);
  id values = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];
NSLog(@"json values=%@",values);
}];

Method 2

 NSMutableDictionary *dictionnary = [NSMutableDictionary dictionary];
 [dictionnary setObject:textfieldOne.text forKey:@"dishname"];
 [dictionnary setObject:textfieldTwo.text forKey:@"description"];
 NSError *error = nil;
 NSData *submitData = [NSJSONSerialization dataWithJSONObject:dictionnary
 options:kNilOptions
 error:&error];   
 NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://www.example.com/phpfile.php"]];
 [request setHTTPMethod:@"POST"];
 [request setValue:@"application/json" forHTTPHeaderField:@"Accept"];
 [request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
 [request setValue:@"json" forHTTPHeaderField:@"Data-Type"];
 [request setValue:[NSString stringWithFormat:@"%d", [jsonData length]]  forHTTPHeaderField:@"Content-Length"];
 [request setHTTPBody:jsonData]; 
 [NSURLConnection sendAsynchronousRequest:submitrequest
                                   queue:[NSOperationQueue mainQueue]
                       completionHandler:^(NSURLResponse *response, NSData *data, NSError *error)
     {
   NSString *jsonString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
  NSLog(@"jsonString values=%@",jsonString);
  id values = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];
NSLog(@"json values=%@",values);
}];
