If I understand your post correctly, what you need to do is grab the $HTTP_GET_VARS of an URL.

Suppose your link is:

http://www.domain.com/file.php?id=12

When you click on the link, file.php is requested from the server. To view the URL appendage, you can do this:

echo $HTTP_GET_VARS["id"];

which would display '12'.

If the link consisted of multiple GET vars (seperated by ampersands), you could loop through the array $HTTP_GET_VARS and extract all of those values. Suppose the link was:

file.php?id=12&user=jake&home=PA

You can extract all of the variables appended to the URL like this:

while(list($k,$v)=each($HTTP_GET_VARS)) {
echo $k . "=" . $v . "<br />";
}

which would display:

id=12
user=jake
state=PA

Once you have the variables extracted on the server, what you do with 'em from there is your business...

Most of the time the .php?id=14 thing in php stores the variables after the .php as php variables thus you could just do something like this with it:

$SQL = "SELECT * FROM users WHERE id=" . $id;

and so it would go to the Database and look for an entry with the id of 14 in users.

if it does not store it as a php variable you could always use this to store it yourself:

$id = $_GET['id'];
