Question

我真的无法弄清楚为什么我的代码无法正常工作，因为Twilio的调试器不会给我错误，所以我不知道该怎么做......我正在尝试使用Twilio在REST api中进行顺序拨号所以它应该保持按顺序呼叫号码，直到一个人接听为止。这是我到目前为止编写的代码。我正在使用会话来跟踪电话。

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;

}

}

我有这个其他文件相同，顺序拨号使用php和twilio的Dial动词编写，Dial动词的参数允许它传递数组索引但在我的情况下我不知道如何传递数组索引参数...什么想法？

<?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;没有按照您的想法行事。如果这是一个会话变量，则应将其写为$_SESSION['X']=0;。

要发现这些问题，请将错误报告启用到最高级别，然后将错误记录到文件中，然后再查看该文件。它会给你一些提示。

请参阅Error Handling and Logging ^Docs。
