php - How can I use Session Variables to output login username -

-

i'm building application , have added login page works well, communicating "username" , "password" field in database. after logging in, takes page users authorized see.

is there way can display "welcome, xxx" particular user logged in @ next page? , more importantly, output detailed information of logged in user on next page? thanks.

you can use session temporarily store data can seen across page.... after checking successful login credential, can stores user data in session

<?php      session_start();           $_session['username'] = $user_name;     ?>

after storing user data in session,you can access data across different pages until unset session data

<?php  session_start();      if (!isset($_session['username'])) {    echo 'welcome, '.$_session['username'];  } else { echo 'sorry, not logged in.'; } ?>

when user logged out,unregister session variable. unregistering of session variable can done in following way:

<?php session_start(); unset($_session['username']); ?>

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
