使用cURL输出

Question

I'm planning to record the live tweets on a particular topic. For the same, I'm using the twitter stream API with cURL in PHP.

Here is the code:

<?php

$username = "xxxxx";
$password = "xxxxx";


$ch = curl_init();

curl_setopt($ch, CURLOPT_URL, 'https://stream.twitter.com/1/statuses/filter.json?         track=SEARCH_PARAMETER');
curl_setopt($ch, CURLOPT_USERPWD, $username.":".$password);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
$result = curl_exec($ch);
$jsonOBJ = json_decode ($result);

curl_close($ch);

print_r($jsonOBJ);
?>

My problem is, if I set CURLOPT_RETURNTRANSFER to 0, I can see the tweets on the terminal. But I'm not able to store in the variable $jsonOBJ and print it.

Please Help!

I'm working on the same kind of thing as well :) The problem is that when you do it in terminal, it's a stream, so the connection stays alive until you kill it. (ie the curl_exec() doesn't finish)

Try looking at CURLOPT_PROGRESSFUNCTION and CURLOPT_READFUNCTION. They might give you some hints.
