If you look closely enough, only one digit in the value is different. So the base64 encoded value has to differ only some values, not the whole string. 4MjtzO is different than 4NDtzO is different than 4NTtzO You see? So, the whole string is different and thus unique.

[PHP] base64 encode question
Hi all, I have a short script that I want to store the last login time
and the host IP number (harcoded for the moment). Those two variables
are stored in $last_login, which is an array.
[EMAIL PROTECTED] test]# cat lt.php
time(), 'host' => "192.168.10.100");
$serialize_last_login = serialize($last_login);
print "$serialize_last_login\n";
$encoded_serialize_last_login = base64_encode($serialize_last_login);
print "encoded value is: $encoded_serialize_last_login\n\n";
?>
[EMAIL PROTECTED] test]#
When I ran the script, I can see that $serialize_last_login have
different value for 'time'. But why does $encoded_serialize_last_login
always show the same value? Below is the output after running the
script for 3 times:
[EMAIL PROTECTED] test]# php lt.php
a:2:{s:4:"time";i:1207208982;s:4:"host";s:14:"192.168.10.100";}
encoded value is:
YToyOntzOjQ6InRpbWUiO2k6MTIwNzIwODk4MjtzOjQ6Imhvc3QiO3M6MTQ6IjE5Mi4xNjguMTAuMTAwIjt9
[EMAIL PROTECTED] test]# php lt.php
a:2:{s:4:"time";i:1207208984;s:4:"host";s:14:"192.168.10.100";}
encoded value is:
YToyOntzOjQ6InRpbWUiO2k6MTIwNzIwODk4NDtzOjQ6Imhvc3QiO3M6MTQ6IjE5Mi4xNjguMTAuMTAwIjt9
[EMAIL PROTECTED] test]# php lt.php
a:2:{s:4:"time";i:1207208985;s:4:"host";s:14:"192.168.10.100";}
encoded value is:
