[RESOLVED] Handling arrays and objects

[phpSimon]

Hi everyone

I'm using the Twitter API to return an array of results, but things like while(list) or foreach don't seem to work as I expect when I come to print them.

I think it's due to the presence of what I think is an object within the array but I don't know much about the structure of arrays and objects.

Here's the first result within the array. I don't know if I've tabbed the layout correctly.

Array (
   [0] => stdClass Object (
     [location] => Brooklyn: 40.716468,-73.614032 
     [profile_image_url] => http://a2.twimg.com/profile_images/123.jpg 
     [created_at] => Tue, 24 Aug 2010 08:42:56 +0000 
     [from_user] => Freakyy_WK 
     [metadata] => 

   stdClass Object ( 
      [result_type] => recent ) 
      [to_user_id] => 71520846 
      [text] => @Choose_Diime dats close enough 
      [id] => 2147483647 
      [from_user_id] => 138613636 
      [to_user] => chOOse_Diime 
      [geo] => 
      [iso_language_code] => en 
      [source] => <a href="#">uberTwitter</a> ) 

What I want to do is the equivalent of :

while(list($item, $location, etc etc etc)
{
print ($item." - ".$location."<br />");
}

Can anyone point me in the right direction please? And any hints on what this type of array is will be really appreciated!

I'd probably do something like:

foreach($whatever_it_is as $obj) {
   printf(
      "<li>Location: %s, Text: %s</li>\n",
      $obj->location,
      $obj->metadata->text
   );
}

Thank you, I'll try that.

Excellent, works well. The text item isn't inside another object so, with some layout changes, I did this:

foreach($results as $obj) {
   printf(
      "<li>From: %s, (%s,) %s</li>\n",
      $obj->from_user,
      $obj->location,
      $obj->text
   );
}

Thank you for your time, that's an amazingly efficient chunk of code!

Now I need to work out a jQuery solution to continually perform the twitter API search and scroll the results... but that's another question!

[phpSimon]

Update to this question! What would be the most efficient way of - rather than printing these values - assigning them to variables instead?

[phpSimon]

My rather inelegant solution to get two items I want from the Object $result is:

foreach($result as $key => $value) {
  if ($key == 'text'){$textresult = $value;}
  if ($key == 'anotherfieldiwant'){$field2result = $value;}
}

It works but I'm sure there's a nicer way!
