[SOLVED] md5 query

[otuatail]

Hi I have been using md5() for password encription and noticed something here that looked odd.

 

I am happy with $x = md5("mypassword");

but this . . . .

 

f

unction hash_pass($pass){
   $salt="blabla"; //must be the same as all your other files
   return md5($pass.$salt);
}
$user = "username";
$pass = "pasword";
$pass = hash_pass($pass);

 

Not shure what the full stop in the middle does.  $pass.$salt

 

Looks to me loke a class but this is PHP right?

Sorry worked it out. Spent the last few months with something called c#

It is just adding to strings together first.

 

What an idiot.

It's concatenation operator. It appends right string after the left one.

So if $pass is "foo" and $salt is "blabla" then

$pass.$salt = "fooblabla";

 

Not a class at all  (although you can have classes and objects and all that in PHP)
