php - Session not working without any error -


i have login system in session's applied when user has logged in. know long time, right? login works charm no session can applied afterwards. i've tried var_dump it, print_r it, , echoing without success without error. brother out?

code

<?php   require_once $_server["document_root"] . '/project-school/config/init.php'; session_start();  error_reporting(e_all);  ini_set('display_errors', 'on');    if (isset($_post['submit-admin-login'])) { $username=db_escape($koneksi, $_post['username']); $password=db_escape($koneksi, md5($_post['password']));   if(empty($username) || empty($password))      {         $_session['pesan'] = 'username dan password wajib diisi dengan benar';         $_session['alert'] = 'danger';         header('location:../login.php');     }     else     {         $sqladmin= "select * admin username='$username' , password='$password'";         $queryadmin= mysqli_query($koneksi, $sqladmin) or die(mysqli_error($koneksi));                   $resultadmin= mysqli_num_rows($queryadmin);          $sqlpengajar= "select * pengajar username_login='$username' , password_login='$password'";         $querypengajar= mysqli_query($koneksi, $sqlpengajar) or die(mysqli_error($koneksi));         $resultpengajar= mysqli_num_rows($querypengajar);          if($resultadmin > 0)         {             while ($row = mysqli_fetch_array($queryadmin)) {                 $_session['username_admin'] = $row['username'];                 $_session['level']          = $row['level'];                 }             echo $_session['username_admin'];             header('location: ../view/admin-dashboard.php');         }         elseif($resultpengajar > 0)         {             while ($row = mysqli_fetch_array($querypengajar)) {             $_session['nip']                = $row['nip'];             $_session['nama_lengkap']       = $row['nama_lengkap'];             $_session['level']              = $row['level'];             $_session['username_pengajar']  = $row['username_login'];             $_session['alamat']             = $row['alamat'];             $_session['tempat_lahir']       = $row['tempat_lahir'];             $_session['tgl_lahir']          = $row['tgl_lahir'];             $_session['jenis_kelamin']      = $row['jenis_kelamin'];             $_session['agama']              = $row['agama'];             $_session['foto']               = $row['foto'];             }             echo $_session['username_pengajar'];             header('location: ../view/pengajar-dashboard.php');         }         else         {             $_session['pesan'] = 'username atau password anda salah';             $_session['alert'] = 'danger';             header('location: ../login.php');         }     }        }

the session starts after num_rows

try starting session before required statement. like

<?php  session_start(); require_once $_server["document_root"] . '/project-school/config/init.php';

always start session @ first whenever going use sessions, otherwise php doesn't reads it.

you on high risk of sql injections. learn prepared statements keep safe sql injections

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
