[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
?
$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;
?
[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:
YToyOntzOjQ6InRpbWUiO2k6MTIwNzIwODk4NTtzOjQ6Imhvc3QiO3M6MTQ6IjE5Mi4xNjguMTAuMTAwIjt9

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. Hope this helps! -- Aschwin Wesselius /'What you would like to be done to you, do that to the other'/
Re: [PHP] Base64 Encode
I have register globals off, and am using both $HTTP_GET_VARS['goto'] and $_GET['goto']. The problem is not with receiving it, the problem is sending it.

Re: [PHP] Base64 Encode
From: Stephen [EMAIL PROTECTED]
I have a PHP script that works on older versions of PHP but on 4.3, it
outputs nothing. Here's my code:
?php
echo 'SCRIPT language=JavaScript type=text/javascript'.\n
.\n.'if (document.location == top.location)'.\n
.' top.location=home.php?goto='
.base64_encode($_SERVER[REQUEST_URI]).';'.\n
.'/SCRIPT';
?
The problem is, when it redirects, the URL variable goto is empty. I'm
assuming this has something to do with base64_encode. Since this code snipet
is on every page of my site, it'd be a hard hassle to change it so is there
a setting in PHP I need to tweak or should I set aside a few hours to edit
this code? If the latter, what should I change it to?
I hope this relates -- I use the code below as a force frame, placing it
at the top of all content pages as an include. (In my case info.php posts to
index.php, which allows any content page that's called directly to be
returned in a frameset.)
?
$path_array = explode(/, $REQUEST_URI);
$page_name = array_pop($path_array);
?
script language=JavaScript
!--
if (top.location == self.location) {
top.location.href = info.php?contents= + ?=$page_name?
}

/script

Re: [PHP] Base64 Encode
What about $_GET['goto']??? Sounds like another register_globals issue. Also, instead of base64 encoding, you may want to use the rawurlencode and rawurldecode functions.
