[RESOLVED] Merging 2 variables

iNFERiON

I am trying to 2 merge 2 variable into one.
I have a file on my server that holds md5 encrypted passwords like this:

$pass01 = "md5md5md5md5"; // Off course there is a real hash there, just edited it for security.
$user01 = "John Doe";
$group01 = "admin";

What I'm trying to get done is to have PHP combine this info with a login form I made, it should check wheter $pass01 corresponds to that of "John Doe" but should do so outside the password file. I tried this:

if(md5($_POST['pass']) == $pass . $_POST['user'] . '') {

which should create $pass01, if user 01 logs in, $pass02 if user 02 logs in etc. Although it doesn't and I can't figure out why. What am I doing wrong here ?

Also it would be the best if users could login on the form using their name, rather then their number, right now all I use $user01 for is for greeting purposes, but would be great if it compared that name as being the username and see if the pass matches, but not sure how to do that, any hints on that are welcome too 🙂

$var3 = $var1 . $var2;

Hmm, no that's not working.

When I enter this:

$userpass = $pass . $_POST['user'];
echo $userpass;
exit;

it just echoes $_POST['user']. I also tried "$pass" and "\$pass" but with no effect.

is $pass even populated with a value? I see $pass01, but no $pass... so $pass.$POST['user'] is going to make a string with an empty $pass value, and whatever the $POST value is....

Not too clear of what you want to do but this works for sure

$userpass =$_POST['user01'].$_POST['pass01']  ;
echo $userpass;

//OR

$userpass =$pass.$_POST['pass01']  ;
echo $userpass;

//Untill $pass has a value this works fine,
// if not it wud just display value from $_POST['pass01']

its NOT posible to make an variable name out of 2 otehr vars or texts,

you should try using an array

$pass[01] can be formatted by doing:

$pass[$POST['user']] // if the $POST['user'] would be 01 ofcourse

enjoy 😉

Not to debunk you... but you can....
Variable Variables

He would need to use this syntax:

$$_POST['user01'] = $pass;

That would give you a variable with the username as the varaible name, and hte pass as the value...

Thanks that did the trick, I now have:

if(md5($_POST['pass']) == $pass[$_POST['user']]) {

and in the passfile I have:

$pass[User1] = "md5hash";

and I can now log in with User1 and the password I set for it 🙂

but you cant use that to generate an name of an var, only to echo things

$wibble = 'Hello, World!';

$first_part = 'wib';
$second_part = 'ble';

$variable = $first_part.$second_part;

$output = $$variable;

What is the value of $variable? What is the value of $output?

Saiko, please RTFM before you start making claims like that. You can create dynamic varialbes, they're call "variable variables". And yes, it is possible. Weedpacket and I have both shown that it works. Even the manual proves it works.
