Re: [PHP-DB] Session start

2010-05-14 Thread Dustin Simpson 

Barry,

   session_start(); will not wipe clean the user's session so there is 
something else going on.


   Does the login.html authentication script correctly set 
$_SESSION['username'] ?


   Also, it has been my experience that code like 
isset($_SESSION['username']) is better if you replace it with 
array_key_exists('username',$_SESSION)


Thanks,

I have a problem with my system, not sure how I can fix this one. A user has
a log in page and takes them to different pages, now each of these pages has
a check to make sure they are logged in with the following code:

session_start();
if (!(isset($_SESSION['username'])  $_SESSION['username'] != '')) {
header (Location: login.html);
exit;
}

So if they are not logged in it redirects them to the log in page. No
problems there.

Now if a user is not logged in and comes back to that page, it starts the
session so giving them a session id and redirects them back to thge login
page. The problem I have is I do NOT want the session to start, I need them
to hit the log in page with no sessions there. I have tried all sorts but
just cannot get this to work.

I have tried adding this to the code.

session_start();
if (!(isset($_SESSION['username'])  $_SESSION['username'] != '')) {
*session_destroy();*
header (Location: login.html);
exit;
}

But that did not work? Please I am stuck for ideas?

[PHP-DB] Re: **{SPAM}** [PHP-DB] numeric string to single digit array

2008-03-25 Thread Dustin Simpson 

Richard,

   Someone might have a quicker/better way, but what about:

?php

   $numbers = '1223123';
   $numberarray = str_split($numbers,1);
   print_r($numberarray);
?

Thanks,

Can anyone tell me how how to convert a string of integers into an array of single digit 
integers.  i.e. 1223123 into ['1','2,','2','3','1,'2','3'] ?  When I retreive 
a column of single digit integers I end up with a long string of numbers.  I think PHP is 
seeing this as one whole number and therefore is not splitting or exploding it. I hope I 
am wrong in my thinking and there is a simple solution, though I am not seeing it.  Can 
anyone help me?

Richard.

Re: [PHP-DB] Autorunning a file

2007-10-09 Thread Dustin Simpson 

Alexander,

   Assuming you are on a *nix machine and php is installed in 
/usr/local you could schedule a cron job with the command:


   /usr/local/bin/php  phpfile.php

   where phpfile.php is the file you want to execute.

Hope this helps.

Thanks,
   --Dustin

Any idea of a way to do this?
