立即行动。
我需要使用这两个数组来随机化问题，但问题是＆＃39;并且回答＆＃39;需要匹配，我不知道该怎么做。
<?php
$question=[
"Favourite game?","Favourite Drink?","Favourite Fast Food?","Favourite TV show?","Favourite chocolate?"
];
$answer=[
["Super Mario","Battlefield", "Counter Strike", "Fifa"],
["Coke","Tea","coffee","Water"],
["Pizza","Fish and Chips","Burger","Hot Dog"],
["The Walking Dead","Prison Break","Breaking Bad","Game of Thrones"],
["Mars","Snickers","Diary Milk","Galaxy"]];
?>
<form action="results.php" method="get">
<input type="hidden" name="timer" id="timer"/>
<p>You have 120 seconds (2 minutes) to answer <?php print $numofquestions ?> question(s)</p>
<br>
<?php
for($i = 0; $i<$numofquestions; $i++)
{
print "<p>".$question[$i]."</p><select name='answer[]'>";
for($j = 0; $j<count($answer[$i]); $j++)
{
print "<option value = '".($j + 1)."'>".$answer[$i][$j]." </option>";
}
print "</select>";
}
?>
<br>
<br>
<input type="submit" name="submit" value="Submit Answers" onclick="sendto()">
</form>
此代码允许我在questions.php
中获取问题的数量
?php
session_start();
$_SESSION['firstname'] = $_GET['firstname'];
$fname = $_SESSION['firstname'];
$_SESSION['numofquestions'] = $_GET['numofquestions'];
$numofquestions = $_SESSION['numofquestions'];
?>中的php
<?php
$question=[

$answer=[

["Pizza","Fish and Chips","Burger","Hot Dog"],
["The Walking Dead","Prison Break","Breaking Bad","Game of Thrones"],

制作一系列密钥并将其随机化。使用以下行更改for($i = 0; $i<$numofquestions; $i++)
$keys = array_keys($question);
shuffle($keys);
foreach($keys as $i)

意味着您需要与正确答案匹配吗？如果是这样的话：
你可以用多维数组和使用array_key_exists之后将问题和答案联系起来，就像那样
<?php
$question = array(1 => "Favourite game?",
2 => "Favourite Drink?",
3 => "Favourite Fast Food?",
4 => "Favourite TV show?",
5 => "Favourite chocolate?");
$answer = array(
1 => array('right_answer' => "Super Mario", "Battlefield", "Counter Strike", "Fifa"),
2 => array("Coke","Tea",'right_answer' => "coffee","Water"),
3 => array("Pizza","Fish and Chips",'right_answer' => "Burger","Hot Dog"),
4 => array("The Walking Dead",'right_answer' => "Prison Break","Breaking Bad","Game of Thrones"),
5 => array("Mars",'right_answer' => "Snickers","Diary Milk","Galaxy")
）;
这只是一种意识形态，希望有所帮助

我尝试了你的代码，调整了一下，我限制了$ keys数组，只包含用户指定的问题数量。至少有两种等效的方法可以实现相同的行为。
<?php
//This is less error prone
$numofquestions = $_GET['numofquestions'];
for($i = 0; $i < $numofquestions; $i++) {
$question_trimmed[$i] = $question[$i];
}
$keys = array_keys($question_trimmed);
shuffle($keys);
和
<?php
//this is shorter
$numofquestions = $_GET['numofquestions'];
$keys = range(0, $numofquestions - 1);
shuffle($keys);
试试它们，并告诉我们您的问题是否已解决
注意：您不需要$cnt变量或最后一个条件语句if(!$cnt--) break;。
