Question

我正在尝试在php中进行简单的三个问题测验。用户登录后，他们开始测验，并有15分钟完成它（我有会议部分计算出来）。一个真/假，一个多项选择和一个简短答案。每个问题在每个页面上单独显示。

我的问题是到目前为止我的逻辑是否正确。由于多个语法错误，此程序将无法运行。它告诉我删除它们应该在那里的括号。例如，在第55行，它告诉我应该删除最后一个}

  if ($selected_radio == 'false') {
  correct()
  }

有人可以看看这个，并给我一些关于去哪里的指示？如果我完全偏离正轨，请告诉我如何向前迈进。例子很棒。

我感谢你的时间。由于这很长，我在这里上传了代码：http://paste.bradleygill.com/index.php?paste_id=339313

我的代码：

<?php
ini_set('session.gc_maxlifetime',900);
ini_set('session.gc_probability',1);
ini_set('session.gc_divisor',1);
//echo ini_get("session.gc_maxlifetime"); 
session_start();
if($_SESSION['loggedin'] !== 1) {
header('Location: login.php');
exit;
}

if (!session_is_registered("number"))
{
$_SESSION["number"] = 0;
$_SESSION["answer"] = 0;
$_SESSION["correct"] = 0;
}

$total_number = 3;

print <<<TOP

$number = $_SESSION["number"];

Answer 1

不，这不是正确的做法。老实说，这里有太多的内容甚至是真正的批评。发布较小的样本会更容易。

我突然想到了一些事情：

重复代码 - 希望将其纳入函数
逻辑，数据和HTML都混合在一起。这不好。

这是人们在嘲笑PHP时所指的代码。对不起，如果这听起来很刺耳，但这是真的。

PHP中的测验 - 我这样做了吗？
