Keeping only the last 3 items in Session array Laravel
Hi,
I'm using Laravel and keeping track of recently viewed item ID's in a 'recent' array.
To store them I use: Session::push('recent', $id) when a user visits an item details page.
After visiting a few items, my array when dumped looks like:
array:6 [▼
0 => "17918"
1 => "18204"
2 => "17180"
3 => "18119"
4 => "17897"
5 => "18119"
]
I'm only after the last 3 items (just showing last 3 items you visited). How can I store just the last 3 all the time instead of continually adding to the array? I thought I could just 'use' the last 3 items in the array but as a user continues to visit detail pages, the array will just keep getting larger. I was thinking array_slice perhaps to keep it to 3 but couldn't figure out how to implement in this case. Any suggestions/direction would be great.
Thanks as always.
PS: I'm nearly through this project and never would have made it without all the help I've received on this site. Thanks again.

$recent = Session::get('recent');
if (!is_array($recent)) {
$recent = array();
}
$recent[] = $id;
while (count($recent) > 3) {
array_shift($recent);
}
Session::put('recent', $recent);
