Question

My website shows recommend pages for users. Right now, I suppose to send a query to get a URL addresses. It will be annoying to my server to get every single URL addresses. So, I would like to get 5 URL addresses from db and store them in to session as array.

array (
  url[0] => google.com/1
  url[1] => google.com/2
  url[2] => google.com/3
  url[3] => google.com/4
  url[4] => google.com/5
)

It would like to store like this, and I would like to remove the first value after a user visits.

array (
  url[0] => google.com/2
  url[1] => google.com/3
  url[2] => google.com/4
  url[3] => google.com/5
)

It will be like this after first step.

array (
  url[0] => google.com/5
)

At the end, there will be only one left in the session. After this, the server will send a query to get 5 different URL addresses. So, can you give me an idea how to set this up?

Take a look at array_shift

Example use:

$array = array("google.com/1", "google.com/2", "google.com/3");
array_shift($array);
print_r($array);

output:

Array
(
    [0] => google.com/2
    [1] => google.com/3
)
