1,保证各部分编码统一(utf8)

使用工具phpstudy【http://www.phpstudy.net/】

写单独PHP文件时,在<?php前面不能留空行,不然会报错

1.1在数据库配置文件mysql.ini

 

1.2建立新的数据库,表,每个字段时:

1.3在前端页面时定义编码

<meta charset="UTF-8">

2.PHP链接数据库页面active.php

<?php
  	$conn=mysql_connect("localhost","root","root");
	mysql_select_db("music",$conn);
	mysql_query(\'SET NAMES utf-8\');
?>

3.将数据嵌入html


<ul id="ul">
  <?php

    include("active.php");
    $arr=mysql_query("select * from musicinfo",$conn);
    while($res=mysql_fetch_row($arr)){
      echo "<li href=".$res[4]."><b>".$res[1]."</b><span>".$res[2]."</span><a href=".$res[3]."></a></li>";
    }
  ?>
</ul>


4,向数据库内添加资源(form表单提交)

<form action="" method="post">

  <p><b>用户名:</b><input type="text" name="username"></p>
  <p><b>密码:</b><input type="text" name="password"></p>

 <input type="submit" value="注册" name="submit">
<form>
<?php include("active.php"); if(isset($_POST[\'submit\']) and $_POST[\'submit\']=="注册"){ $username=$_POST[\'username\']; $password=$_POST[\'password\']; $insert=mysql_query("insert into localauth(user_id,username,password) values(null,\'$username\',\'$password\')",$conn); } ?>

 5,删除某条特定的数据

<table>
<form action="" method="post" > <?php include \'base.php\'; $arr=mysql_query("select * from musicinfo",$conn); while($res=mysql_fetch_row($arr)) echo "<tr><td>".$res[0]."</td><td>".$res[1]."</td><td>".$res[2]."</td><td>".$res[3]."</td>
          <td>".$res[4]."</td><td><button name=\'delete\' type=\'submit\' value=\'".$res[0]."\'>删除</button></td></tr>"; ?> </form>   <?php if(isset($_POST[\'delete\'])){ $thisId=$_POST[\'delete\']; $del=mysql_query("delete from musicinfo where music_id=\'$thisId\'",$conn); if($del){ echo "<script>alert(\'删除成功!\');window.location.href=\'music_list.php\';</script>;"; }else{ echo "<script>alert(\'失败!\');</script>";
       } }
?> </table>
