输出多维数组，只显示单选按钮（嵌套的foreach循环）

所以我试图输出一个简单的测验的多维数组。我认为这是一个逻辑错误，但我在这个问题上摸不着头脑。问题和答案选择不会显示在浏览器中，但所有的单选按钮都可以。输出多维数组，只显示单选按钮（嵌套的foreach循环）

任何帮助/提示将不胜感激。

<body> 
<?php 
$q_and_ans = array(
    array('question' => 'What\'s the narrators name?', 
     'ans' => array(
      'Greg Scmitz', 
      'Greg Sanders', 
      'Greg Smith'), 
      'correct_ans' => 0), 
array('question' => 'What is Greg\'s new friend\'s name?', 
    'ans' => array(
     'Jose', 
     'Man`enter code here`uel', 
     'Manuelo'), 
     'correct_ans' => 1), 
array('question' => 'What beer are they drinking?', 
    'ans' => array(
     'Pacifico', 
     'Corona', 
     'Pilsener'), 
     'correct_ans' => 2), 
array('question' => 'Where was the Mariscopa video taken?', 
    'ans' => array(
     'Ecuador', 
     'El Salvador', 
     'Mexico'), 
     'correct_ans' => 1), 
array('question' => 'What was in the narrator\'s bowl that he failed to mention?', 
    'ans' => array(
     'Shrimp', 
     'Octopus', 
     'Squid'), 
     'correct_ans' => 0), 
array('question' => 'What color was Manuel\'s shirt?', 
    'ans' => array(
     'Green', 
     'White', 
     'Blue'), 
     'correct_ans' => 2), 
array('question' => 'What was printed on the beer bucket?', 
    'ans' => array(
     'Corona Light', 
     'Corona Extra', 
     'Modelo'), 
     'correct_ans' => 1), 
array('question' => 'What kind of vehicle is behind Manuel?', 
    'ans' => array(
     'Car', 
     'Truck', 
     'There is no vehicle'), 
     'correct_ans' => 1), 
array('question' => 'What color is the roof over the narrator\s head?', 
    'ans' => array(
     'Brown', 
     'Tan', 
     'Green'), 
     'correct_ans' => 2), 
array('question' => 'What kind of animal is on Manuel\s shirt?', 
    'ans' => array(
     'Aligator', 
     'Duck', 
     'There is no animal'), 
     'correct_ans' => 0), 

) 
?>

我认为这个问题是在嵌套的foreach循环

<form method="post" action=""> 

    <?php 
     foreach($q_and_ans as $i => $q_and_an):?> 

      <p><?php $q_and_an['question']?></p> 
      <?php foreach($q_and_an['ans'] as $a => $ans): ?> 
      <input type="radio" value="$a" name="question[$i]"> <?php $ans ?> 

      <?php endforeach;?> 
    <?php endforeach;?> 

    <input type="submit" name="submit" id="submit"> 
</form>

“值=” $”名称= “的问题[$ i]” $和$我是不能在PHP标签。而且我会用<?php echo $q_and_an['question'];?>

但现在我只能选择一个出口30个收音机的？嗯 – theBartender

<？PHP \t \t \t的foreach（$ q_and_ans为$ I => $ q_and_an）：？？？？？> \t \t

<？php foreach（$ q_and_an ['ans'] as $ a => $ ans）：？> ”name =“question []”><？php // $ ANS> \t \t \t
\t \t \t – theBartender

'<形式方法= “POST” 行动= “” > <？PHP的的foreach（$ q_and_ans为$ I => $ q_and_an）：>

$ ans）：？> ”name =“question [<？php echo $ i;？>]” ><？php echo $ ans; ？> ' – bin
