Im using a login code snippet from a friend in one of my apps.
He accesses the user logged in by doing:
$username_from_cookie = $_COOKIE[$cookiename];
How can I get the other elements in that array?
I've tried print_r() and the page returns blank as if php parsing stopped.
You can use print_r() or var_dump() to inspect the contents of the $_COOKIE array. Like so:
var_dump($_COOKIE);
or:
print_r($_COOKIE);
Hope this helps :)

I have some PHP that displays the users session name in the HTML and if the user is not logged in, then I would like it to display "User" instead.
Can I have an if statement in this case? I tried it myself but I got header errors.
This is what I've tried so far but each practical attempt just spits out more errors at me.
This is a different approach I have tried.
<?=$_SESSION['sess_user'] or ("User");?>!
<?php echo (isset($_SESSION['sess_user']) ? $_SESSION['sess_user'] : "User"); ?>
This will check if the session is set, if it is then echo the session, if it isn't then it will echo "User".

I have a project in which i have to make a code in which when we click on menu bar and the option that we select in menu bar the page related to that option will display all this is to be done through my sql.Is there any way to do this task.
I don't understand exactly what you want and if there is a better way to do this, but don't put in your sql fields PHP code.
You can create a xml document instead, and use it better.PHP.net - XMLdocument

I am trying to call drupal 6 URL from my local system, that URL will generate a xml file.
My system does not have drupal intallation. I tried file_get_content("www.abc.com") but it does not write my xml file but when I try to run the url normally it runs and xml file gets generated.
Thanks in advance
You can use sockets or just file_get_contents, like
$homepage = file_get_contents('http://www.example.com/');
echo $homepage; // $homepage contains server response without headers

http://www.aliexpress.com/item/NEW-7-Android-2-3-256MB-DDR2-4GB-NAND-Flash-7-inch-tablet-pc/498159194.html - I got this link
Here you can see a buttons: bundle, color
If you click some of them the price will change, but the question is how can I parse that behaviour to my page via php?
The problem is that I can't understand where is javascript code that executes this, or how to find it, maybe someone got ideas about that?
Inspecting that page's source code I can see that the skuProducts variable in javascript contains this information encoded into a JSON-string. You can't really run this javascript code on your webserver, so you'll have to devise another way to get that variable's value - and then you can use json_decode() to get the contents.
Note that changing the amount of items results in an AJAX call to a shipping costs calculator. You could probably simulate that, but I'm not sure that webshop would like that (and it might be illegal).

I have two PHP files: A.php and B.php. A passes $id to B using POST and B can get $id the first time but I need to jump back to B again using Header. This time the parameter gets lost.
How can I pass the parameter when I use Header to jump back?
You must Use $_REQUEST instead of $_POST so it will work in both case . and when you use header to jump back again use query string with same name.
you can pass id variable in the query string when you redirect.
