PHP サイト全体の権限検証コードの例:

  1. < html>
  2. < >< タイトル>e
  3. < /title >
  4. </頭><
  5. > ="login.php"
  6. メソッド="POST" >ユーザー:
    < 入力 type=

  1. 名前= "ユーザー名"><
    br> ; パスワード:
    1. < input type="pass単語「
      名前=」 「パスワード」>
    2. < 入力 type =「送信」
      value ="确定">
    3. < 入力 タイプ =「リセット」
      =「取消」 >
    4. < ; /form>
    5. < /body&g t;
    6. < /html>

    -----conn.php---------- ----------------

    1. < ?php
    2. $ホスト='127.0 .0.1';  
    3. $mysql_user='root';  
    4. $mysql_password='qeephp';  
    5. $mydb=「学ぶ」;  
    6. $link = mysql_connect($host,
      $mysql_user , $mysql_password)
    7. or die("無法连接数据库: "
      . mysql_error()) ;  
    8. mysql_select_db($mydb);  
    9. ?>
