此处仅将HF PHP&MySQL上的主要代码做注释和笔记（虽然一步步来很精彩 不过对于笔记来说~）。

   

数据库连接与插入数据：

    1 <?php

    2   $first_name = $_POST['firstname'];

    3   $last_name = $_POST['lastname'];

    4   $when_it_happened = $_POST['whenithappened'];

    5   $how_long = $_POST['howlong'];

    6   $how_many = $_POST['howmany'];

    7   $alien_description = $_POST['aliendescription'];

    8   $what_they_did = $_POST['whattheydid'];

    9   $fang_spotted = $_POST['fangspotted'];

   10   $email = $_POST['email'];

   11   $other = $_POST['other'];

   12

   13   $dbc = mysqli_connect('data.aliensabductedme.com', 'owen', 'aliensrool', 'aliendatabase')//此处用来连接数据库 格式：域名或者ip 用户名 密码 选用的数据库

   14     or die('Error connecting to MySQL server.');//连接失败的反馈

   15

   16   $query = "INSERT INTO aliens_abduction (first_name, last_name, when_it_happened, how_long, " .

   17     "how_many, alien_description, what_they_did, fang_spotted, other, email) " .

   18     "VALUES ('$first_name', '$last_name', '$when_it_happened', '$how_long', '$how_many', " .

   19     "'$alien_description', '$what_they_did', '$fang_spotted', '$other', '$email')";//MySQL的插入语句  对应的column插入对应的值

   20

   21   $result = mysqli_query($dbc, $query)//执行query语句

   22     or die('Error querying database.');

   23

   24   mysqli_close($dbc);//要有访问完数据库就关闭的良好习惯  数据库的并发访问有限

   25

   26   echo 'Thanks for submitting the form.<br />';

   27   echo 'You were abducted ' . $when_it_happened;

   28   echo ' and were gone for ' . $how_long . '<br />';

   29   echo 'Number of aliens: ' . $how_many . '<br />';

   30   echo 'Describe them: ' . $alien_description . '<br />';

   31   echo 'The aliens did this: ' . $what_they_did . '<br />';

   32   echo 'Was Fang there? ' . $fang_spotted . '<br />';

   33   echo 'Other comments: ' . $other . '<br />';

   34   echo 'Your email address is ' . $email;

   35 ?>
