Twilio REST API順序撥號

Question

我真的不知道爲什麼我的代碼不工作，因爲Twilio的調試器不給我錯誤，所以我不知道該怎麼辦......我試圖在REST中進行順序撥號api使用Twilio所以它應該保持呼叫號碼，直到一個人拿起..Below是我迄今爲止寫的代碼。我正在使用會話來跟蹤呼叫。

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的撥號動詞我有這等文件相同，順序diallnig寫，撥號動詞的參數，允許它通過在我的情況數組的索引，但我不知道如何傳遞數組索引參數....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 
} 
?>

您的代碼有語法錯誤等。

例如SESSION['X']=0;沒有做你認爲它正在做的事情。如果這是一個會話變量，它應該寫爲$_SESSION['X']=0;。

要發現這些問題，請將錯誤報告啓用到最高級別，然後將錯誤記錄到文件中，然後觀察該文件。它會給你一些提示。

請參閱Error Handling and Logging ^Docs。
