[Encrypting db.php page?]

Actually I came across a little script somewhere that allows you to enter a .php url into a form, and you can view the unparsed source of any .php page, remotely hosted... it IS possible. Kinda freaked me out when I saw how easy it was. Looks like Zend is my best option, as I can't afford to pay out of pocket for that other one. I just need to figure out how to use it.

[Encrypting db.php page?]

How can I secure my db.php (I have it named something else) page so if somebody finds it, they can't just view source and see the database login information? Is there a way to easily encrypt it? I've heard of Zend, and know it is enabled on my server, but I have NO clue as to how to use it. Please give me some suggestions. Thanks!

[An question about include()]

Yep, you are asking about functions.

[Sessions / Cookies]

It is important that you don't have any kind of output before session_start(); - except for coments. A space between php open and session_start(); will killl you.

correct:

[code]
<?
session_start();

session_destroy();
?>[/code]

Incorrect:
[code]
<?

session_start();

session_destroy();
?>[/code]

[How do I echo a session variable?]

Have you checked that your form is actually posting employeenumber?
On that previous page, after the form is submitted, try something like this...
[code]if (isset($empcode))
{
echo "Employee: $empcode";
} else { echo "Null"; }[/code]

If it returns as Null, then your problem is in the form.

Also, when setting your session variable... session_register

[code]               
session_register('empcode');
$_SESSION['empcode'] = $empcode;[/code]

I assume you set $_SESSION['empcode'] on another page?

$_SESSION['empcode'] = "blah";

That should be on a previous page.  Also, make sure you're not using the "back" button in your browser to go back and reset the value.

You can also try print_r($_SESSION) to look at what is in the session array.

Thanks for that... I've been trying to figure out how to see what is in the session array. You gave me a parse error though... don't forget the blessed ; !!

print_r($_SESSION);

[can u use if($a == 5 AND $b == 5)]

Same question... what do you mean by different priorities? I have always used AND.

[Join query - please help]

I need to pull up all [b]distinct[/b] userid_numbers out of [i]table1[/i] (To see who is online and in that location, excluding duplicate results), and then query [i]table2[/i] for each userid_number to get profile information, and then display in a table on the website.

So basically, I need to join these two queries...

[code]$query1 = "SELECT DISTINCT usernumber FROM table1 WHERE useronline_location='$location'";[/code]

to get the list of usernumbers (in an array?)... then run the following query in a loop, so it gets the information for each usernumber...

[code]$query2 = "SELECT * FROM table2 WHERE uidnum='$usernumber'";

// Display table here

[/code]



Can somebody assist? Thanks
