我正在创建一个web form的全部功能，该功能可以从文件中检索10 random questions和answer key，并将它们作为测验显示给用户，然后对结果进行评分。我遇到的problem是，当进行submitting测验时，程序会尝试将separate set of questions和answers与输入进行比较，而不是对原始问题进行评分。我知道代码远非完美，但我确实需要帮助了解为什么它会继续重建测验。
我没有从当前位置调用get_questions()函数，而是尝试将其放在display_form()函数的开头，这导致了某种不确定的错误。我也尝试过使用各种if语句来调用get_questions（）函数，希望使该函数仅运行一次。什么都没有。
代码：
function get_questions(){
$TFQuestArray = file("TFQuestions.txt");
$TFAnswersArray = file("TFAnswers.txt");
$Tmp = array_combine($TFQuestArray, $TFAnswersArray);
$Keys = array_keys($Tmp);
shuffle($Keys);
foreach ($Keys as $Key)
{
$TFShuffledArray[$Key] = $Tmp[$Key];
}
$TFQuestArray = array_keys($TFShuffledArray);
$TFAnswersArray = array_values($TFShuffledArray);
// this section of code repeats the above process with the Fill in the blank Q and A's
$FIBQuestArray = file("FIBQuestions.txt");
$FIBAnswersArray = file("FIBAnswers.txt");
$Tmp = array_combine($FIBQuestArray, $FIBAnswersArray);
$Keys = array_keys($Tmp);
shuffle($Keys);
foreach ($Keys as $Key)
{
$FIBShuffledArray[$Key] = $Tmp[$Key];
}
$FIBQuestArray = array_keys($FIBShuffledArray);
$FIBAnswersArray = array_values($FIBShuffledArray);
// in any event the code goes on but it builds the questions just fine, it pulls 4 True False, 3 Fill in the Blank, and 3 Multiple choice and creates an array containing the proper values.
$GetQuestionsTF = array_slice($TFQuestArray, 0, 4);
$GetQuestionsMC = array_slice($MyChoiceQuestions, 0, 3);
$GetQuestionsFIB = array_slice($FIBQuestArray, 0, 3);
global $QuizQuestions;
$QuizQuestions = array_merge($GetQuestionsTF, $GetQuestionsMC, $GetQuestionsFIB);
$GetCorrectAnswersTF = array_slice($TFAnswersArray, 0, 4);
$GetCorrectAnswersMC = array_slice($MCAnswersArray, 0, 3);
$GetCorrectAnswersFIB = array_slice($FIBAnswersArray, 0, 3);
global $QuizAnswers;
$QuizAnswers = array_merge($GetCorrectAnswersTF,$GetCorrectAnswersMC, $GetCorrectAnswersFIB);
// this is the display form function

$AnswerFive, $AnswerSix, $AnswerSeven, $AnswerEight, $AnswerNine, $AnswerTen, $QuizChoices, $QuizAnswers) {
