I'm having a little trouble with losing my array order after using unset(). Here's the code first:
$id = $_GET['id'];
for($i = 0; $i < count($my_array); $i++)
{
if($my_array[$i] == $id)
{
unset($my_array[$i]);
}
}
Assume that $my_array has 4 items and $my_array[1] is equal to $id. After I unset that I try to run a ...
Hi,

So I know the exact path the node I would be attempting to remove. I am iterating through several xml files to update some of the content. In order to add some of the new content in, I must first delete the content that already exists.

After learning how to "correctly" unset a node, I noticed that using PHP's unset() function leaves the tabs and spaces behind. So now I have this big chunk of white space in between nodes at times. I'm wondering if PHP iterates through blank spaces/returns/tabs and whether it would eventually slow down the system.
I'm also asking whethe...

The problem sounds like this:
The log-in using sessions works perfect on my localhost, but when the EXACTLY same files are uploaded to my host (hostgator), the sessions don't or, or they get messed up. Also the log-out feature doesn't work on the host.
I've checked and every page has the session_start(); inside it.

Why this code doesn't work?
public function get($key) {
return isset($_SESSION[$key]) ? &$_SESSION[$key] : false;
