Delete from array help
- by Camran
I have a cookie which stores info in an array.
This is for a classifieds website, and whenever users delete their 'ads' the cookie must also be removed of the ad which was deleted.
So I have this:
if (isset($_COOKIE['watched_ads'])){
$expir = time()+1728000;
$ad_arr = unserialize($_COOKIE['watched_ads']);
foreach($ad_arr as $val){
if($val==$id){ // $id is something like "bmw_m3_10141912"
unset($val);
setcookie('watched_ads', serialize($ad_arr), $expir, '/');
}
}
}
This doesn't work... any idea why? I think its a problem with the unset part...
Also, keep in mind if there is only one value inside the array, what will happen then?
Thanks
