37）PHP,获取数据库数据并在html中显示（晋级4）
我的php文件和html文件的位置关系：
然后我的主php文件是b.php，我的那个配置文件是BBB.php，我的html文件是login.html
然后我的b.php代码展示：
1 <?php 2 class db 3 { 4 public $host ;//= "localhost";//定义默认连接方式 5 public $User;//= "root";//定义默认用户名 6 public $Pwd;//= "root";//定义默认的密码 7 public $Dbname ;//= "thkphp5";//定义默认的数据库名 8 public $my_sql; 9 public $link; 10 public $result; 11 /* 12 * 构造函数 13 * 主机名，使用者，使用者密码，数据库的名字，查询语句 14 */ 15 public function __construct($config) { 16 $this->host=$config['host']; 17 $this->User=$config['user']; 18 $this->Pwd=$config['pwd']; 19 $this->Dbname=$config['dbname']; 20 $this->my_sql=$config['sql']; 21 $this->link= $this->connect(); 22 $this->result= $this->Query($this->my_sql); 23 } 24 25 //成员方法 是用来执行sql语句的方法 26 /* 27 * 数据库查询函数 28 * $sql string 是你的查询语句 29 */ 30 public function Query($sql) 31 //两个参数：sql语句，判断返回1查询或是增删改的返回 32 { 33 $db = $this->connect(); 34 $r = $db->query($sql); 35 if (isset($r)) { 36 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 37 } else { 38 return "数据库查询失败！"; 39 } 40 41 42 } 43 /* 44 * 数据库连接函数 45 */ 46 public function connect(){ 47 $Link= mysqli_connect($this->host,$this->User,$this->Pwd,$this->Dbname); 48 return $Link; 49 } 50 51 } 52 $sql='select * from zixun;'; 53 $config=include './BBB.php'; 54 $shujuku=new db($config); 55 56 57 include './login.html'; 58 //var_dump($shujuku->result); 59 60 ?>
我的BBB.php文件展示：
1 <?php 2 return $config=array( 3 'host'=>"localhost", 4 'user'=>"root", 5 'pwd'=>"root", 6 'dbname'=>"thkphp5", 7 'sql'=>$sql);
我的html代码展示：
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><th>ZX_name</th><th>ZX_fenlei</th><th>ZX_zuozhe</th><th>更新时间</th><th>浏览次数</th><th>发布状态</th> 13 </tr> 14 <?php foreach($shujuku->result as $row) : ?> 15 <tr> 16 <td><?php echo $row[0];?></td> 17 <td><?php echo $row[1];?></td> 18 <td><?php echo $row[2];?></td> 19 <td><?php echo $row[3];?></td> 20 <td><?php echo $row[4];?></td> 21 <td><?php echo $row[5];?></td> 22 <td><?php echo $row[6];?></td> 23 </tr> 24 <?php endForeach;?> 25 </table> 26 </body> 27 </html>
我的结果展示：
数据库代码展示：
