if (session_is_registered("ses_fs_userid"))检测已经注册并赋值了，但为什么还输不出来呢？

Question

可以试一下楼上的。echo $_SESSION['ses_fs_userid'];

stan23(小刀) ;
还是不行。 function user_login($user_name,$pwd){
    session_start();
  if(!session_is_registered("ses_fs_userid")){
  $user_name=addslashes(htmlSpecialChars(trim($user_name)));
          $pwd==addslashes(htmlSpecialChars(trim($user_name)));
  $fs_userd=str_replace(" ","",$user_name);
          $fs_passd=md5(str_replace(" ","",$pwd));   $lc_log_isno=new_sql_much("id","assman"," where a_userid='".$fs_userd."' and a_password='".$fs_passd."' and a_state='2'");
         if($lc_log_isno==0){ 
 echo "<script>";
 echo "window.location.href='../login/login.php';";
 echo "</script>";
 return false;
 }   session_register("ses_fs_recid");
      session_register("ses_fs_userid");
      session_register("ses_fs_alias");
      session_register("ses_fs_power");
      session_register("ses_fs_gdpower");
      session_register("ses_fs_allfen");
      session_register("ses_fs_manno");
      session_register("ses_fs_kind");
   $sql_user="select id,a_userid,a_alias,a_power,a_gdpower,a_allfen,a_manno,a_kind from assman where a_userid='".$fs_userd."' and a_password='".$fs_passd."' and a_state='2'";
   $res_user=new DB_Sql($sql_user);
           while($res_user->next_record()){
               $ses_fs_recid=$res_user->f(id);
   $ses_fs_userid="stripslashes($res_user->f(a_userid))";
   $ses_fs_alias=stripslashes($res_user->f(a_alias));
               $ses_fs_power=$res_user->f(a_power);
               $ses_fs_gdpower=$res_user->f(a_gdpower);
               $ses_fs_allfen=$res_user->f(a_allfen);
               $ses_fs_manno=$res_user->f(a_manno);
               $ses_fs_kind=md5($res_user->f(a_kind));
   }
   $res_user->free();
   }else{
     return false;
   }
     
   
   
   }调用函数后。就对$ses_fs_userid赋了值，但为什么输不出来呢？

Answer 2

如果你用session_register函数注册session变量，那么请确认register_globals=on。另外需保证被注册的变量是全局变量。
你的注册是在函数中进行的，又没有全局变量声明。当然不可能得到正确的结果

Answer 3

你用记事本打开当前session会话的文件，文件名是sess*，看看不就知道赋值了没有
唠叨老大说的没错
