我正在进行这个测验。但是我的表格出了问题。该页面显示一个随机问题,但不是显示4个不同的答案选项,而是重复一次选项4次。我该如何解决这个问题?
<?php
//retrieve question list:
$get_questions = $con->prepare("SELECT question_ID, question FROM questions");
$get_questions->execute();
$get_questions->bind_result($question_ID, $question);
$questions = array();
while ($get_questions->fetch()) {
$questions[$question_ID] = array($question_ID, $question, array());
}
// retrieve answer list:
$get_answers = $con->prepare("SELECT id, question_ID, answers, correct FROM answers");
$get_answers->execute();
$get_answers->bind_result($id, $question_ID, $answers, $correct);
while ($get_answers->fetch()) {
$questions[$question_ID][2][$id] = array($id, $answers, $correct);
}
// Scramble the array and print:
shuffle($questions);
?>
