Twilio REST API顺序拨号

Question

我真的不知道为什么我的代码不工作，因为Twilio的调试器不给我错误，所以我不知道该怎么办......我试图在REST中进行顺序拨号api使用Twilio所以它应该保持呼叫号码，直到一个人拿起..Below是我迄今为止写的代码。我正在使用会话来跟踪呼叫。

文件名：dial.php

<?php 
session_start(); 



    require 'Services/Twilio.php'; 
    $version = "2010-04-01"; 

$arr = array('4167641123','6478604321','9058553456'); 



    $sid = '....'; 
    $token = '...'; 
    $from = '....'; 
    $to = '416.....'; 
    $callback = 'www.site.com/dial.php'; 

    $client = new Services_Twilio($sid, $token, $version); 

    //if this is our very first call then CallStatus should be empty so it means we can use the emptiness of this variable 
    //to trigger our very first call 
    if (!(isset($_REQUEST['CallStatus']))) 
    { 
    try { 
     $call = $client->account->calls->create(
      $from, 
      $arr[0], 
      'http://demo.twilio.com/welcome/voice/', 
      array('Timeout' => 1, 
        'StatusCallback' => $callback) 
      ); 
      var_dump($call); 
     } catch (Exception $e) { 
      var_dump($e); 
     } 
} 
// if the CallStatus variable is not empty then the else statement will execute 
else 
{ 
//if this part of code runs for the first time, it means this is our 2nd call because the 1st person did not pick up 
//this means the second number in the array will be called 
//each time this statement runs it adds a 1 to the index of the array but if the last index number called was the final and 
//last number in the array, then this statement wont run and instead session at the bottom if statement will be initialized to 0 
//so that if this script is ran again it will start off from the first number in the array 
if (!($_SESSION['X']>=count($arr)-1) && isset($_REQUEST['CallStatus']) && ($_REQUEST['CallStatus']=='failed'|| $_REQUEST['CallStatus']=='no-answer' || $_REQUEST['CallStatus']=='busy')) 
{ 

$_SESSION['X']=$_SESSION['X']+1; 

    try { 
     $call = $client->account->calls->create(
      $from, 
      $arr[SESSION['X']], 
      'http://demo.twilio.com/welcome/voice/', 
      array('Timeout' => 1, 
        'StatusCallback' => $callback) 
      ); 
      var_dump($call); 
     } catch (Exception $e) { 
      var_dump($e); 
     } 
} 
//initializes the session to 0 because if we have reached to this else statement, 
//then it means the if statement above did not run and we have already called the last person 
//in the phone number array so we are at an end and we must close the program 
//by leaving session at 0 for the next trial to run properly 
else 
{ 

$_SESSION['X']=0; 

} 

} 

使用PHP和twilio的拨号动词我有这等文件相同，顺序diallnig写，拨号动词的参数，允许它通过在我的情况数组的索引，但我不知道如何传递数组索引参数....任何想法？

<?php 

// Set the numbers to call 
$numbers = array("<number to call 1>", "<number to call 2>", "<number to call n>"); 
$number_index = isset($_REQUEST['number_index']) ? $_REQUEST['number_index'] : "0"; 
$DialCallStatus = isset($_REQUEST['DialCallStatus']) ? $_REQUEST['DialCallStatus'] : ""; 

header("content-type: text/xml"); 

// Check the status of the call and 
// that there is a valid number to call 

if($DialCallStatus!="completed" && $number_index<count($numbers)){ 
?> 
    <Response> 
    <Dial action="attempt_call.php?number_index=<?php echo $number_index+1 ?>"> 
     <Number url="screen_for_machine.php"> 
     <?php echo $numbers[$number_index] ?> 
     </Number> 
    </Dial> 
    </Response> 
<?php 
} else { 
?> 
    <Response> 
     <Hangup/> 
    </Response> 
<?php 
} 
?>

您的代码有语法错误等。

例如SESSION['X']=0;没有做你认为它正在做的事情。如果这是一个会话变量，它应该写为$_SESSION['X']=0;。

要发现这些问题，请将错误报告启用到*别，然后将错误记录到文件中，然后观察该文件。它会给你一些提示。

请参阅Error Handling and Logging ^Docs。
