使用CURL仅获取最新推文的ID

Question

$ch = curl_init("http://api.twitter.com/1/statuses/user_timeline/nafhameducation.json");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$latest_tweet = curl_exec($ch);
$latest_tweet_id = $latest_tweet[0]->id_str;
curl_close($ch);

I'm using this code to get the ID of the latest tweet on my time line, However $latest_tweet_id returns an empty string, any idea why it's not getting what I need?

Answer 1

Try

 $latest_tweet = json_decode(curl_exec($ch));

Curl returns text. Turn up your error reporting, btw, you should have been getting PHP errors, trying to access a string as an object.

Also, in debugging this, it would have been useful to var_dump($latest_tweet); after line 3 -- that should have made it clear that the type of $latest_tweet was not an object.
