Twitter API Cursor PHP

Question

Bereits habe ich ein Skript, das die ersten 5000 Benutzer von Freunden/IDs sammelt. Ich möchte alle Freunde sammeln, also muss ich durch Cursor bewegen, um sie zu bekommen. Ich denke, ich verstehe, wie der Cursor funktioniert, aber ich kann es immer noch nicht funktionieren lassen. Ich versuche next_cursor zu erreichen, weiß aber nicht, was ich falsch mache.

Es scheint, dass der Cursor, den ich versuche zu bekommen, nicht richtig aufgerufen wird.

Möchte ein Feedback mit diesen, weil Twitter-API kein reales Beispiel gibt.

<?php 

header("Content-Type: text/html;charset=utf-8"); 
ini_set('display_errors', 1); 
require_once('TwitterAPIExchange.php'); 
session_start(); 
$user = $_POST['nombre']; 
$_SESSION['user']=$_POST['nombre']; 
$usuario = $user; 


$servername = "localhost"; 
$username = "root"; 
$password = ""; 
$dbname = "twitter"; 

// Create connection 
$conn = new mysqli($servername, $username, $password, $dbname); 
// Check connection 
if ($conn->connect_error) { 
    die("Connection failed: " . $conn->connect_error); 
} 


/** Set access tokens here - see: https://dev.twitter.com/apps/ **/ 
$settings = array(
'oauth_access_token' => "k1", 
'oauth_access_token_secret' => "k2", 
'consumer_key' => "k3", 
'consumer_secret' => "k4" 

); 

//https://api.twitter.com/1/followers/ids.json?cursor=-1&screen_name=microsoft 

$cursor = "cursor=".-1; 
$url = 'https://api.twitter.com/1.1/friends/ids.json'; 
$getfield = '?'.$cursor.'screen_name='.$usuario; 
$requestMethod = 'GET'; 


$twitter = new TwitterAPIExchange($settings); 
$json = $twitter->setGetfield($getfield) 
->buildOauth($url, $requestMethod) 
->performRequest(true, array(CURLOPT_CAINFO => dirname(__FILE__) . '/cacert.pem')); 

$arrayFriends = json_decode($json, true,512,JSON_BIGINT_AS_STRING); 

echo 'Usuario' .";". 'Nombre'.";".'Location'.";".'Numero Amigos'.";".'Numero  followers'.";".'Descripcion'."\n"; 

foreach($arrayFriends['next_cursor'] as $curs){ 
foreach($arrayFriends['ids'] as $obj){ 
while($cursor != 0){ 
    //$cursor->$arrayFriends['ids']->next_cursor; 
    $cursor = $curs; 
    //$cursor = "&cursor=" + $cursor; 
    $sql = "INSERT INTO friends (user, id) VALUES ('$usuario','$obj')"; 
    if ($conn->query($sql) === TRUE) { 
     //echo "New record created successfully"; 
     header("Location:logic.php"); 
    } else { 
     echo "Error: " . $sql . "<br>" . $conn->error; 
    } 
} 
    } 
} 
$conn->close(); 

?>

Versuchen Sie diesen Code. Es wird bis zu 3000 Freunde holen.

Laufzeit des Skripts ist ca. 3-5 Minuten
