首先是我的文件关系：
我的b.php是主php文件，BBB.php是配置文件，login。html是显示文件，
b.php文件代码：
1 <?php 2 /** 3 * Created by PhpStorm. 4 * User: Interact 5 * Date: 2017/8/14 6 * Time: 12:08 7 */ 8 9 class db 10 { 11 public $host ;//= "localhost";//定义默认连接方式 12 public $User;//= "root";//定义默认用户名 13 public $Pwd;//= "root";//定义默认的密码 14 public $Dbname ;//= "thkphp5";//定义默认的数据库名 15 public $my_sql; 16 public $link; 17 public $result; 18 19 /* 20 * 构造函数 21 * 主机名，使用者，使用者密码，数据库的名字，查询语句 22 */ 23 public function __construct($config) { 24 $this->host=$config['host']; 25 $this->User=$config['user']; 26 $this->Pwd=$config['pwd']; 27 $this->Dbname=$config['dbname']; 28 $this->my_sql=$config['sql']; 29 $this->link= $this->connect(); 30 $this->result= $this->Query($this->my_sql); 31 } 32 /* 33 * 数据库查询函数 34 * $sql string 是你的查询语句 35 */ 36 public function Query($sql) 37 //两个参数：sql语句，判断返回1查询或是增删改的返回 38 { 39 $db = $this->connect(); 40 $r = $db->query($sql); 41 if (isset($r)) { 42 return $r->fetch_all();//查询语句，返回数组.执行sql的返回方式是all，也可以换成row 43 } else { 44 return "数据库查询失败！"; 45 } 46 47 48 } 49 /* 50 * 数据库连接函数 51 */ 52 public function connect(){ 53 $Link= mysqli_connect($this->host,$this->User,$this->Pwd,$this->Dbname); 54 return $Link; 55 } 56 57 } 58 $sql='select ZX_id ,ZX_name from zixun '; 59 $config=include './BBB.php'; 60 $shujuku=new db($config); 61 62 63 include './login.html'; 64 //var_dump($shujuku->result); 65 66 ?>
我的BBB.php文件：
1 <?php 2 return $config=array( 3 'host'=>"localhost", 4 'user'=>"root", 5 'pwd'=>"root", 6 'dbname'=>"thkphp5", 7 'sql'=>$sql);
我的login.html文件：
1 <!-- 模板文件，利用HTML代码展示数据 --> 2 <!DOCTYPE html> 3 <html lang="en"> 4 <head> 5 <meta charset="UTF-8"> 6 <title>比赛列表</title> 7 </head> 8 <body> 9 10 <table> 11 <tr> 12 <th>ZX_id</th> 13 <th>ZX_name</th> 14 <!--<th>ZX_fenlei</th>--> 15 <!--<th>ZX_zuozhe</th>--> 16 <!--<th>更新时间</th>--> 17 <!--<th>浏览次数</th>--> 18 <!--<th>发布状态</th>--> 19 </tr> 20 <?php foreach($shujuku->result as $row) : ?> 21 <tr> 22 <td><?php echo $row[0];?></td> 23 <td><?php echo $row[1];?></td> 24 <!--<td><?php echo $row[2];?></td>--> 25 <!--<td><?php echo $row[3];?></td>--> 26 <!--<td><?php echo $row[4];?></td>--> 27 <!--<td><?php echo $row[5];?></td>--> 28 <!--<td><?php echo $row[6];?></td>--> 29 </tr> 30 <?php endForeach;?> 31 </table> 32 </body> 33 </html>
结果展示：
我的数据库代码：
