2、列表页(index.php)
<?php
$link=mysqli_connect('localhost','root','','a');
//然后是指定php链接数据库的字符集
mysqli_set_charset($link,'utf8');
$sql="select * from search";
//模糊查询出像数据库中的title或者content里面的值或者说像数据库中的title或者content里面的某一段值相对应的就行了,就可以输出啦
$result=mysqli_query($link,$sql);//运行sql
?>
<!--显示的效果-->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<table border="1" cellpadding="5">
<tr>
<td>id</td>
<td>种类</td>
<td>物品</td>
<?php
while ($row=mysqli_fetch_array($result)) {//把对象编程数组输出，不然会报错哦
# code...
?>
<tr>
<td><?=$row['id'];?></td>
<td><?=$row['content'];?></td>
<td><?=$row['type'];?></td>
<td><a href="update.php?id=<?php echo $row['id']; ?>" rel="external nofollow" >更新</a></td>

3、delete.php
<?php

//然后是指定php链接数据库的字符集
mysqli_set_charset($link,'utf8');
//$sql = "DELETE FROM `search` WHERE `id` = '$_POST[id]'";
//模糊查询出像数据库中的title或者content里面的值或者说像数据库中的title或者content里面的某一段值相对应的就行了,就可以输出啦
$result=mysqli_query($link,"DELETE FROM search WHERE id ='$_GET[id]'");//运行sql
echo "<script>alert('恭喜你，删除成功了');location.href='index.php';</script>";
?>
4、update.php

$link=mysqli_connect('localhost','root','','a');
//然后是指定php链接数据库的字符集
mysqli_set_charset($link,'utf8');
//$sql = "DELETE FROM `search` WHERE `id` = '$_POST[id]'";
//模糊查询出像数据库中的title或者content里面的值或者说像数据库中的title或者content里面的某一段值相对应的就行了,就可以输出啦
$result=mysqli_query($link,"UPDATE search set content='$_GET[content]',type='$_GET[type]' WHERE id ='$_GET[id]'");//运行sql
$sql="select * from search";
//模糊查询出像数据库中的title或者content里面的值或者说像数据库中的title或者content里面的某一段值相对应的就行了,就可以输出啦
$result=mysqli_query($link,$sql);//运行sql
echo "<script>alert('恭喜你，更新成功了');location.href='index.php';</script>";

5、create.php

//然后是指定php链接数据库的字符集
mysqli_set_charset($link,'utf8');
$sql='select * from type';
$re = mysqli_query($link,$sql);
while($arr = mysqli_fetch_array($re)){
echo "<option value='".$arr['type']."'>".$arr['type']."</option>";
}
?>
</select>
</td>
<input type="submit" value="创建">
</form>
</body>
</html>
<?php
if(!$_POST['content']||$_POST['type']==-1)

exit();
}
$content=$_POST['content'];
$type=$_POST['type'];
$link=mysqli_connect('localhost','root','','a');
//然后是指定php链接数据库的字符集
mysqli_set_charset($link,'utf8');
$sql = "INSERT INTO search(content,type)
VALUES ('{$content}','{$type}')";
$result=mysqli_query($link,$sql);
if($result)
