$nbt = $item->getNamedTag() ?? new CompoundTag("", []);
$nbt->test = new IntTag("test", 69);
$item->setNamedTag($nbt);

/** @var Item $item */
if (isset($item->getNamedTag()->test)) {
    //$item has NBT tag: test.
    /** @var int $test */

How to check if He Held And remove when he held something else?
@minijaham

 

There's an event that detects it. might want to look for that yourself

 

Yes
PlayerItemHeldEvent but when he held that item it gives him effects but it won't remove when he held something else?

@minijaham

 

Check if the item is not the item you want.
And simply remove it

 

How?

 

PHP:

on item held event {
    if event->getItem === Your item {
        Code to give effect
        return;
    }
    code to remove effect
}


Something like this should work

 

I should remove but if he use regeneration potion it also remove it!

 

Well I think that problem is a different story.
You can cancel consume event for regen potion :shrug:

 

You can use PlayerMoveEvent or PlayerInteractEvent:

PHP:

use pocketmine\event\PlayerInteractEvent;
public function onInteract(PlayerInteractEvent $e)
{
$nbt = $item->getNamedTag() ?? new CompoundTag("", []);
$nbt->test = new IntTag("test", 69);
$item->setNamedTag($nbt);

/** @var Item $item */
if (isset($item->getNamedTag()->test)) {
    //$item has NBT tag: test.
    /** @var int $test */
    $test = $item->getNamedTag()->test->getValue(); //69
}
}
