與Session變量未定義指數

Question

我有3個Session變量的一個問題

，我有一個文件名爲chat.php是這樣的：

class Chat implements MessageComponentInterface { 
protected $clients; 
protected $data_clients; 
protected $target = "xxxxx"; //conversation target number/JID 

public function __construct() { 
    $this->clients = new \SplObjectStorage; 
    $this->data_clients = new \SplObjectStorage; 

    session_start(); 
    echo 'begin'; 
    $_SESSION["running"] = time(); 
    $_SESSION["inbound"] = array(); 
    $_SESSION["outbound"] = array(); 
    echo 'end'; 

    $this->send_message('hello'); 

    $this->Listen(true); 

} 



public function onError(ConnectionInterface $conn, \Exception $e) { 
    echo "An error has occurred: {$e->getMessage()}\n"; 
    $conn->close(); 
} 

public function Listen($initial){ 
    $band=false; 

    $options = array(
     CURLOPT_HEADER => false, 
     CURLOPT_TIMEOUT => 40000 
    ); 

    $params=['initial'=>$initial, 'target'=>$this->target,'method'=>'prueba']; 
    $defaults = array(
     CURLOPT_URL => 'localhost/socket/src/myApp/script2.php', 
     CURLOPT_POST => true, 
     CURLOPT_POSTFIELDS => http_build_query($params), 
    ); 
    $ch = curl_init(); 
    curl_setopt_array($ch, ($options + $defaults)); 
    curl_exec($ch); 

    if(curl_errno($ch)){ 
     $band=true; 
    } 
    curl_close($ch); 

    if(!$band) 
     $this->Listen(false); 
}//fin Listen 


public function send_message($mensaje){ 

    $band=false; 
    $options = array(
     CURLOPT_HEADER => false, 
    ); 

    $params=['method'=>'sendMessage','target'=>$this->target,'message'=>$mensaje]; 
    $defaults = array(
     CURLOPT_URL => 'localhost/socket/src/myApp/ajax2.php', 
     CURLOPT_POST => true, 
     CURLOPT_POSTFIELDS => http_build_query($params), 
    ); 
    $ch = curl_init(); 
    curl_setopt_array($ch, ($options + $defaults)); 
    curl_exec($ch); 
    curl_close($ch); 


}//fin de enviar mensaje 
} 

所以，我$這個 - > send_message（」你好'）從構造函數調用一個名爲ajax2劇本，但後來我有此錯誤：

Notice: Undefined index: outbound in C:\xampp\htdocs\socket\src\myApp\ajax2.php on line 16 
envia 
Notice: Undefined index: running in C:\xampp\htdocs\socket\src\myApp\socket2.php on line 15 

ajax2的內容是：

<?php 
session_start(); 

$method = $_POST["method"]; 

switch ($method) { 
    case "sendMessage": 
     $target = $_POST["target"]; 
     $message = $_POST["message"]; 
     $outbound = $_SESSION["outbound"]; 
     $outbound[] = array("target" => $target, "body" => $message); 
     $_SESSION["outbound"] = $outbound; 
     break; 
    case "pollMessages": 
     $inbound = @$_SESSION["inbound"]; 
     $_SESSION["inbound"] = array(); 
     $profilepic = @$_SESSION["profilepic"]; 
     $ret = new JSONResponse(); 
     if ($profilepic != null && $profilepic != "") { 
      $ret->profilepic = $profilepic; 
     } 
     $_SESSION["profilepic"] = ""; 
     if (count($inbound) > 0) { 
      foreach ($inbound as $message) { 
       $ret->messages[] = $message; 
      } 
     } 
     echo json_encode($ret); 
     break; 
} 

那麼，問題出在會話變量，我不知道我做錯了，我已經作出在session_start均勻。如果你看到，我在構造中創建它們，然後在ajax2中使用它們。謝謝！

它不工作，因爲你是在試圖訪問會話變量$ _SESSION [ 「出站」]，$ _ SESSION [ 「入站」]，$ _ SESSION一個完全不同的會話[ 「profilepic」 在ajax2.php

通過session_start（）導致會話在chat.php中創建;與session_start（）在ajax2.php中創建的會話不同。導致你正在通過CURL訪問ajax2.php，這會在ajax2.php中創建一個新的部分，這將與chat.php中的會話不同。
