How do i create an array of ALL players and loop though them all

How do i create an array of ALL players from \players\ directory and loop though them all? i want to do this because i want to get a list of all players and see if any of them are offline.

 

The players folder could contain up to thousands of players depending on how popular/old your server is. Why not make a much smaller array of the current players online and check if the player is online that way?

PHP:

 foreach ($this->getServer()->getOnlinePlayers() as $player) {
//check if the player is online here
} 

 

Ok, I have a plugin for ppl who bought a rank on my server, and I have stored all of them in a .Json file in the config folder

I want to loop through them and check if any of them are offline because I want to have a timmer that continues even if the player is offline or online

That better explains what I'm trying to do.

 

Can you let us know how the JSON file looks like? Is it just a sequential array of player names or are they mapped to something?

 

PHP:

{
    "AtomizationYT": {
        "rank": "vip",
        "timeout": 20000
    },
    "JustRealPetey84": {
        "rank": "vip",
        "timeout": 20000
    }
}

i want to loop though everyone in this file and check if they are offline...
This only works when the player is online, thus, the timer only goes down when they are online, but i want the opposite.

PHP:

class Timeout extends PluginTask{

public $defaultTime = 86400; //24 hours in seconds
 
    public function __construct($plugin){
        $this->plugin = $plugin;
        parent::__construct($plugin);
    }
 
    public function onRun($tick){

$timeoutDB = new Config($this->plugin->getDataFolder()."players.json", Config::JSON);
$timeoutDB->save();

$onlinePlayers = $this->plugin->getServer()->getOnlinePlayers();

foreach($onlinePlayers as $player){
$name = $player->getName();

$time = $timeoutDB->getNested($name.".timeout");

if($time > -5){
$time--;

$timeoutDB->setNested($name, ["rank"=>"vip", "timeout"=>$time]);
$timeoutDB->save();

}

}
}
}


 

A smart idea is to use the time() function, so time() + 86400 will be 24 hours from now in seconds

 

It's better to save an expiration date and check if the player's rank is still active, when they join. Looping through all of your offline players will be bad for performance.

 

okay, how do i make an expire date? can i have a code example.

 

For example, time() + timeout in seconds.

 

The time() function returns the UNIX timestamp. The value of time() keeps changing.

PHP:

$time = time();
//wait 3 seconds
$now_time = time();

echo $now_time - $time;//3


 

This is going nowhere (to what i can see).. i want to know how to make a "Cool Down" for how long they must wait before getting the rank again

 

I don't get it, could you explain in more detail?

 

a player runs a command to give him/her a free rank with features for a specific time. How do i create the cool down?

 

So, do you want to make it so the rank would expire, but a player could use the command with a specific cooldown time, which is independent from rank's expiration time (so the rank's expiration time would add up), or the rank would expire and only then the player could use the command again? If you mean the second option, then what @Thunder33345 explained is pretty much what you do, you just should make sure that you check if player's rank has expired or not, when the player uses the command. If you mean the first option, then you should save one more timestamp for the cooldown and check if current timestamp is bigger than the saved one, when the player uses the command.

 

Yes, but I'm not sure how to do it.. May i have a code example?

 

May I hear what you mean? I mentioned two options and you just said "yes".

 

I quoted option 1, which I figured you would understand thats what I wanted help with

 

I don't think you get the point.
You can code anything in any way you want.
If all you want to do is loop through every player, then sure go ahead and use scandir().

PHP:

$folder = "/path/to/my/folder/";
foreach(scandir($folder) as $file){
    $full_path = $folder . $file;
    $data = json_decode(file_get_contents($full_path), true);
}


Sure, you can implement a feature in a million different ways by ignoring performance and CPU time.

You should really look into PHP's time() function which returns the live Unix timestamp. For your case, that's just the right thing to use, that's what everyone is saying.
