jQuery AJAX .post pulling multiple variables from one php -

-

i trying find best way pull multiple variables php ajax post. right now, using .substr split echoed variable php itself.

here's ajax post (with jquery)

$.post("scripts/enter/register.php", {username : username, email : email, password : password}, function(data) {     var callback = data.substr(0,1);     var user_session = data.substr(1);     if(callback === "1"){         //do registration script     } else {         //give error     } });

and php

if (strlen($hash) >= 20) {     if($user_name){         //perform sql queries         echo "1";         echo $cookie;     } else {         echo "0";     } } else {     echo "0"; }

as see, in php, echo 2 variables when goes well. when there's error, echo 1 variable. script works fine, find clunky , apparently unsecure. on side note, have come understand echo not secure, though no 1 has told me instead.

i have script handles login (this last script register), use different php script. here questions:

  1. can combine both register , login (and other php scripts) single script?
  2. is there better way turn php variables javascript variables able use in jquery?

you have if(callback === "1"){ in code.

this should if(callback == "1"){ assuming may number string

that may solve part of problem

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...
