Question

我试图通过以下方式从一个PHP文件发送数组：

$question_records=findQuestions($db,$student_id,$story_id,$call_number);
                echo count($question_records).'<br/>';
                $i=0;
                foreach($question_records as $record=>$question)
                {
                    $questions_file[$i]=$question['file_name'].'_'.$question['concept_tested'];
                    $questions_id[$i]=$question['question_id'];
                    echo "Array Elements:</br>";
                                    echo $questions_file[$i]. "</br>";
                    $i++;
                }

输出：

Array Elements:
q1_comp
q2_vocab
q3_cri

功能makeCall

makeCall($call_id,$phone,$questions_file,$questions_id,$student_id,$story,$call_number);

    function makeCall($call_id,$phone,$questions_file,$questions_id,$student_id,$story,$call_number){
        $questions_file= urldecode(http_build_query($questions_file));
                echo "ECHO NEW STMT questions_file \n";
                echo $questions_file;
                $questions_id= urldecode(http_build_query($questions_id));
                echo "ECHO NEW STMT questions_id \n";
                echo $questions_id;
    }
    $url = $server.'/startCall.php?call_id='.$call_id.'&phone='.$phone.'&questions_id='.$questions_id.'&questions_file='.$questions_file.'&student_id='.$student_id.'&story='
                .$story.'&call_number='.$call_number.'&question_number=0&response=0&count_english=0&count_hindi=0';
    echo '<Redirect method="GET">startCall.php?'.$url.'</Redirect>';

startCall.php

    $questions_id=array('questions_id' => $_REQUEST['questions_id']); 
    $questions_file=array('questions_file' =>$_REQUEST['questions_file']);
    echo "FOR QUESTIONS ID in STARTCALL.PHP";
    echo 'output1'.$questions_file.'</br>';
    echo 'output2'.$questions_file[0];

我得到的输出是

output1Array
output2

但是，我想要做的是访问数组元素（q1_comp，q2_vocab，q3_cri）。有谁知道它为什么不起作用。我已经尝试了所有的东西，并且真的需要这个尽快工作。谢谢！

Answer 1

在startCall.php中尝试以下

echo 'output1'.print_r($questions_file,true).'</br>';

无法接收在PHP中传递的数组元素
