Getting Differnt results from hasing the same string. Help Needed

If i run the following i should be getting the same hash but for some reason they come out different.

$salt="553099";
$pass = "computer";
$password = "computer";
$pass  = sha1('$salt . $pass');
$pass2 = sha1('$salt . $password');

print $pass;
print "<br/>";
print $pass2;

PHP:

It prints

15a53d55ae2af4db3843aa8700729c2332626859
fd78226853ad10dcac53b55748983d1ccf31ffc1

HTML:

Any explanation is appreciated

 

because you're doing it wrong, what happen is instead of 553099computer that should be pass to the sha1 function your actually passing '$salt . $pass' and '$salt . $password' just remove the single quotes..

 

thanks that solved it
