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="https://www.atool.online/article/update.php?id=<?php echo $row['id']; ?>" rel="external nofollow" >更新</a></td> <td><a href="https://www.atool.online/article/delete.php?id=<?php echo $row['id']; ?>" rel="external nofollow" >删除</a></td> </tr> <?php } ?> </tr> </table> <a href="https://www.atool.online/article/create.php" rel="external nofollow" >创建</a> </body> </html>

5、create.php
