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. [root@svr1 test]# cat lt.php <? $last_login = array('time' => 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"; ?> [root@svr1 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: [root@svr1 test]# php lt.php a:2:{s:4:"time";i:1207208982;s:4:"host";s:14:"192.168.10.100";} encoded value is: YToyOntzOjQ6InRpbWUiO2k6MTIwNzIwODk4MjtzOjQ6Imhvc3QiO3M6MTQ6IjE5Mi4xNjguMTAuMTAwIjt9 [root@svr1 test]# php lt.php a:2:{s:4:"time";i:1207208984;s:4:"host";s:14:"192.168.10.100";} encoded value is: YToyOntzOjQ6InRpbWUiO2k6MTIwNzIwODk4NDtzOjQ6Imhvc3QiO3M6MTQ6IjE5Mi4xNjguMTAuMTAwIjt9 [root@svr1 test]# php lt.php a:2:{s:4:"time";i:1207208985;s:4:"host";s:14:"192.168.10.100";} encoded value is: YToyOntzOjQ6InRpbWUiO2k6MTIwNzIwODk4NTtzOjQ6Imhvc3QiO3M6MTQ6IjE5Mi4xNjguMTAuMTAwIjt9 Please help -- Roger -- Sign Up for free Email at http://ureg.home.net.my/
