Stuck With Arrays..

[itsjimmy91]

Hello... I simply am running a query with the Twitter Search API that searches for a specific term and then returns the Tweets it finds. This is a sample of what the array of Tweets returned looks like:

 

array(50) {
 [0]=>
 object(stdClass)#9 (18) {
   ["created_at"]=>
   string(31) "Tue, 11 Dec 2012 04:30:08 +0000"

   string(7) "Cvpcake"
   ["from_user_id"]=>
   int(44610318)

   string( "44610318"

   NULL
 }

 

Now what I want to do is store the "id_str" field of each Tweet into an array. I'm trying to do this and I thought it would be simple, but I must be doing something wrong. Here is what I have, which results in an error.

 

$tweetIds;
   // loop through $results and favorite them
   for($i=0; $i<3; $i++)
   {
    $tweetIds[$i] => $results[$i]['id_str'];
   }

 

I've tried a couple of other things, including...

 

$tweetIds;
   // loop through $results and favorite them
   for($i=0; $i<3; $i++)
   {
    $tweetIds[$i] => $results[$i]["id_str"];
   }

 

and...

 

$tweetIds;
   // loop through $results and favorite them
   for($i=0; $i<3; $i++)
   {
    $tweetIds[$i] => $results[$i][7];
   }

 

But each way has resulted in an error. I can't figure out why. I'm sure it's something simple I'm not doing correctly... thanks for any help

And which errors would those be resulting in?

That second "dimension" isn't an array. It's an object. Which you can tell by the

array(50) {

  [0]=>

  object(stdClass)#9 (18) {

$results[$i]->id_str
