title: Converting NSArray -> JSON -> NSData -> PHP server ->JSON representation
body: <p>I am converting an Array of NSDictionaries to JSON data with the following...</p>
  
  <p>Create my data...</p>
  
  <pre><code>NSMutableArray *arrayOfDicts = [[NSMutableArray alloc] init];
  
  for (int i = 0; i &lt; 2; i++) {
      NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:
                                    @"MySong", @"title",
                                    @"MyArtist", @"artist",
                                    nil];
      [arrayOfDicts addObject:dict];         
  }
   NSArray *info = [NSArray arrayWithArray:arrayOfDicts];
   NSData* jsonData = [NSJSONSerialization dataWithJSONObject:info 
        options:NSJSONWritingPrettyPrinted error:&amp;error];
  </code></pre>
  
  <p>then send like so...</p>
  
  <pre><code>NSURL *url = [NSURL URLWithString:@"http://www.mywebsite.com/index.php"];
      ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
      [request setPostValue:jsonData forKey:@"songs"];
      [request setDelegate:self];
      request.tag = TAG_LOAD_SONGS;
      [request startAsynchronous];
  </code></pre>
  
  <p>This is sending the NSData to my server, but how do I then use it in php... Its really just a bunch of random numbers if I print it from my server, and I have tried using json_encode but I dont think thats meant for raw data...</p>
  
  <p>Any help would be great!</p>
  
  <p>EDIT:
  Here is the Response of php...</p>
  
  <pre><code>echo $_POST['songs'];
