使用php从sql获取登录的用户信息

Question

I read many topics about this problem but i cant find the answer 我读了许多有关此问题的主题，但找不到答案

I want create a page for each user who he can see their info in that page. 我想为每个可以在该页面中看到其信息的用户创建一个页面。 Like profile page. 喜欢个人资料页面。

This is my table: 这是我的桌子：

My session file (db.php): 我的会话文件（db.php）：

<?php 
session_start();
header('Content-Type: text/html; charset=UTF-8');
require ("../functions.php"); 
  mysql_connect($dbHOST, $dbUSER, $dbPASS);
  mysql_select_db($dbNAME); 
function user_login ($username, $password) { 
  $username = mysql_real_escape_string($username); 
  $password = md5($password);
  $result = mysql_query("SELECT * FROM users WHERE username = '".$username."' AND password = '".$password."' AND usergroup = '1'"); 
  $exists = (mysql_num_rows($result))?TRUE:FALSE;
  if (!$exists){ 
      echo "نام کاربری/رمز عبور اشتباه است و یا شما مجوز دسترسی به این بخش را ندارید!"; 
    }
 else { 
     $_SESSION['username'] = true;
 echo "<script language=\"Javascript\">document.location.href='index.php' ;</script>";
} 
}
?>

Login page (login.php): 登录页面（login.php）：

<?php 
header('Content-Type: text/html; charset=UTF-8');
require ("../functions.php"); 
include("db.php"); 
if(isset($_POST['username']) && isset($_POST['password'])){   
    user_login($_POST['username'], $_POST['password']); 
} 
?>

 <span class="pull-right"> پنل مدیریت وبسایت <?php echo $sitetitle ?> </span>
 </div>
</div>
</div>
  <div class="col-md-4 forms">
  <p class="adtitle"> ورود به حساب مدیریت</p>
  <form action="login.php" method="post">
     <div class="col-md-12"><input class="form-control" name="username" type="text" placeholder="نام کاربری" required/></div></br></br>
     <div class="col-md-12"><input class="form-control" name="password" type="password" placeholder="رمز عبور" required/></div></br></br>
    <button style="color:#000;">ورود به حساب</button>
  </form>
  </div>
</body>
</html>

functions.php is used for database information. functions.php用于数据库信息。

Now for example i want to show the user information in user.php page 现在，例如，我想在user.php页面中显示用户信息

Answer 1

Put something like that at the end of your function (before the two } at the end of the code) 在函数末尾放置类似的代码（在代码末尾的两个}之前）

$lId=mysql_result($result, 0, "id" );
$lusername=mysql_result($result, 0, "username" );
echo "User $li is $lusername";

but you are using deprecated mysql_* functions and your mysql query can be attacked by sql injection threats. 但是您正在使用不mysql_*使用的mysql_*函数，并且您的mysql查询可能会受到sql注入威胁的攻击。
