Remove Object from array by object value in php

Question

$followers = [['id'=>0], ['id'=>1]];

So, assuming I have this array, what would be the best way to remove the object by it's id?

That's what i came up with

foreach($followers as $key=>$follower){
    if($follower->id == 0){unset $followers[$key]}
}

is there a better more efficient way?

It is an array not an object, so why are you accessing as an object?

Try this,

foreach ($followers as $key => $follower) {
    if($followers[$key] == 0) {
        unset($followers[$key]);
    }
}

You were accessing values of an array like an object.
You were using unset incorrectly.
You were missing the ; at the end of your unset part.

What I really need is removing an item from array of arrays in my Cache I tried this:

if(Cache::has('user_follower'.$user_id)){
        $user_follower = Cache::get('user_follower'.$user_id);

        foreach($user_follower as $key=>$follower){
            if($follower->user_id == Auth::id()){
                unset($user_follower[$key]);
                Cache::put('user_follower'.$user_id, $user_follower, 30);
                return;
            }
        }

}

I failed sadly, so I'm for now I'm using Cache::forget.
