要发布到同一页面并在问题旁边标记：
<?php
$questions = array(
1=>array(
'question' => 'What is 2+2?',
'answers' => array(
'a' => '4',
'b' => '5',
'c' => 'nothing'
),
'correct' => 'a'
),
2=>array(
'question' => 'Where is paris?',
'answers' => array(
'a' => 'somewhere',
'b' => 'in rome',
'c' => 'in france'
),
'correct' => 'c'
),
3=>array(
'question' => 'What is water?',
'answers' => array(
'a' => 'hydrogen and nitrogen',
'b' => 'hydrogen and oxygen',
'c' => 'hydrocarbon and iron'
),
'correct' => 'b'
)
);
?>
<?php
if( $_SERVER['REQUEST_METHOD']=='POST' ){
$score=0;
$answers=array();
foreach( $_POST['answers'] as $index => $answer ){
if( array_key_exists( (int)$index, $questions ) ){
if( $questions[ (int)$index ]['correct']==$answer ) {
$score++;
}
$answers[(int)$index]=array(
'question' => $questions[ (int)$index ]['question'],
'answer' => $answer,
'correct' => $questions[ (int)$index ]['correct']==$answer
);
}
}
}
?>
<!DOCTYPE html>
<html lang='en'>
<head>
<meta charset='utf-8' />
<title></title>
</head>
<body>
<form method="post" name="quizz" id="quiz">
<?php
if( $_SERVER['REQUEST_METHOD']=='POST' ){

要将测验发布到a-n-other 页面，您需要知道其他页面上的问题和答案。为此，实现这一目标的最简单方法可能是为测验和结果页面使用包含的文件。
包含问题的文件（ questions.php ）
<?php
#questions.php
$questions = array(
1=>array(
'question' => 'What is 2+2?',
'answers' => array(
'a' => '4',
'b' => '5',
'c' => 'nothing'
),
'correct' => 'a'
),
2=>array(
'question' => 'Where is paris?',
'answers' => array(
'a' => 'somewhere',
'b' => 'in rome',
'c' => 'in france'
),
'correct' => 'c'
),
3=>array(
'question' => 'What is water?',
'answers' => array(
'a' => 'hydrogen and nitrogen',
'b' => 'hydrogen and oxygen',
'c' => 'hydrocarbon and iron'
),
'correct' => 'b'
)
);
?>
将表单指向结果页面而不是其自身的测验页面：
<?php
require __DIR__ . '/questions.php';
?>
<!DOCTYPE html>
<html lang='en'>
<head>
<meta charset='utf-8' />
<title></title>
</head>
<body>
<form action='quizresults.php' method="post">
<ol>
<?php foreach( $questions as $questionno => $value ){ ?>
<li>
<h4><?php echo $value['question']; ?></h4>
<?php
foreach( $value['answers'] as $letter => $answer ){
$label = 'question-'.$questionno.'-answers-'.$letter;
?>
<div>
<input type="radio" name="answers[ <?php echo $questionno; ?> ]" id="<?php echo $label; ?>" value="<?php echo $letter; ?>" />
<label for="<?php echo $label; ?>"><!--<?php echo $letter; ?>)--> <?php echo $answer; ?> </label>
</div>
<?php } ?>
</li>
<?php } ?>
</ol>
<input type="submit" value="Submit Quiz" />
</form>
</body>
</html>
以及表单所针对的页面，quizresults.php
<?php
#quiz results
require __DIR__ . '/questions.php';
?>
<?php
if( $_SERVER['REQUEST_METHOD']=='POST' ){
$score=0;
foreach( $_POST['answers'] as $index => $answer ){
if( array_key_exists( (int)$index, $questions ) ){
if( $questions[ (int)$index ]['correct']==$answer ) {
$score++;
}
$answers[(int)$index]=(object)array(
'question' => $questions[ (int)$index ]['question'],
'answer' => $answer,
'correct' => $questions[ (int)$index ]['correct']==$answer
);
}
}
foreach($answers as $index => $arr){
printf(
'<div>[ Question %d ] %s Answer: %s %s</div>',
$index,
$arr->question,
$arr->answer, $arr->correct ? '<span style="color:green">Correct</span>' : '<span style="color:red">Incorrect</span>'
);
}
}
?>
更新：根据评论，实际答案应为绿色/红色
<?php
#quiz results
require __DIR__ . '/questions.php';
?>
<?php
if( $_SERVER['REQUEST_METHOD']=='POST' ){
$score=0;
foreach( $_POST['answers'] as $index => $answer ){
if( array_key_exists( (int)$index, $questions ) ){
if( $questions[ (int)$index ]['correct']==$answer ) {
$score++;
}
$answers[(int)$index]=(object)array(
'question' => $questions[ (int)$index ]['question'],
'answer' => $answer,
'correct' => $questions[ (int)$index ]['correct']==$answer
);
}
}
echo '<ol>';
$percentage=round( ( $score / count( $questions ) ) * 100, 1 );
$message='Appalling!';

if( $percentage == 100 )$message='Outstanding!';

foreach( $questions as $questionno => $value ){
$options=array();
foreach( $value['answers'] as $letter => $answer ){
$label = 'question-'.$questionno.'-answers-'.$letter;
$checked='';
