<div class =“post-text”itemprop =“text”>
  <P>
    这是代码中的一些问题
  </p>
  <OL>
    <LI>
      从哪里和为什么我们
       <code>
        return
      </code>
      ？
    </LI>
    <LI>
      没有关闭html标签
    </LI>
  </醇>
  <P>
    我会像这样改变php代码的最后一部分：
  </p>
   <pre>
    <code>
      <?php
if ($_POST['subButton']) {
    $cart = $_POST['cart'];
    $value = intval($cart);
    $roll = mt_rand(1, 8); // mt_rand() has more entropy than rand()

if ($cart == 'show') {
        // show target locations (according the OP-source)
        for($x = 1; $x <= 8; $x++) {
            echo "<p> You could have ender up in... </p>";
            echo "<h2> " . $train[$x-1] . "</h2>";
        }
    } else if ($value > 0 && $value <= 8) {
        echo "<h2>"."Well, it looks like you're going to " . $train[$value-1] . "! Have fun! </h2>";
        // idk why it needed, but move it here
        if ($value == $roll) {
        }
    } else if ($cart == 'any') {
        echo "<h2>"."Can't handle the pressure? You were selected to go to  " . $train[$roll-1] . "! Have fun! </h2>";
    } else {
        // $_POST['cart'] has something wrong
    }
}
?>

</body>
</html>

</code>
  </pre>
</DIV>

<div class =“post-text”itemprop =“text”>
  <P>
    代替
     <code>
      rand()
    </code>
     使用
     <code>
      mt_rand()
    </code>
     因为
    <a href="http://php.net/manual/en/function.mt-rand.php" rel="nofollow">
      PHP文档
    </A>
     字面上说
  </p>
  <BLOCKQUOTE>
    <P>
      mt_rand锟“生成更好的随机值
    </p>
  </BLOCKQUOTE>
  <P>
    关于你的PHP代码，你有很多错误。这是你的底层PHP代码应该如何看起来：
  </p>
   <pre>
    <code>
      <?php
  if($_POST['subButton']) 
  {
    $cart = $_POST['cart'];
    $roll = mt_rand(0,7);
       //0-7 because those are the values you inserted into
       //the $train[] array

if($cart == 'show') {
      //another correction here, it has to be 0-7
      for($x = 0; $x <= 7; $x++) {
        echo "<p> You could have ender up in... </p>";
        echo "<h2> " . $train[$x] . "</h2>";
      }
    } 
    else if ($cart!='any')
    {
       "<h2>Well, it looks like you're going to " . $train[$cart] . "! Have fun! </h2>";
    }
    else //took out return and placed an else
    {
        echo "<h2>Well, it looks like you're going
        to " . $train[$cart] . "! Have fun! </h2>";
    }

?>

</code>
  </pre>
