Removing a key in array

how would i remove "test" in $back[$sender->getName()] if it exists

PHP:

$back = [];
$item = $player->getInventory()->getItemInHand();
$lore = $item->getLore();
foreach ($lore as $lores) {
                        $back[$player->getName()] = $lores;
                    }
foreach ($back as $parentKey => $keys) {
                        foreach ($keys as $key) {
                            if ($key == "test") {
                                unset($back[$parentKey][$key]);
                            }
                        }
                    }

 

huh, unset($back[$parentKey]["test"])?

 

yes remove test from the parentkey

 

Yeah, just do that, you don't need to loop through $keys btw

 

Code:

 Cannot unset string offsets

 

Okay, well in that case, just unset "test" from $back directly. No foreach loops.
