Need help making plugins

I'm a beginner in PHP programming, I made 2 plugins I want to put on Poggit for GitHub later, and I want them to work perfectly. One plugin crashes my server (a bunch of plugins won't load anymore). The second one, money doesn't work on my plugin (Example: $money = $money - strlen($msg);).

Can you help me fix these 2 plugins?

Plugin 1 – TellMeID:
Server isn't loading 90% of all plugins if my plugin is on my server:

PHP:

<?php

namespace WinterBuild7;

use pocketmine\plugin\PluginBase;
use pocketmine\Player;
use pocketmine\Server;
use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\command\CommandExecutor;
use pocketmine\utils\TextFormat;

class Main extends PluginBase {
    
    public $prefix = "§7[§f§lTellMeID§r§7]§f ";
    
    public function onEnable() {
        $this->getLogger()->info($prefix . "by WinterBuild7 was loaded!");
    }
    
    public function onCommand(CommandSender $sender, Command $command, array $args) {
        if($command->getName() === "tellmeid" && $sender->hasPermission("tellmeid.info")) {
            $sender->sendMessage($prefix . "TellMeID by WinterBuild7. Tells you the item in hand.");
        }
        if($command->getName() === "hand" && $sender->hasPermission("tellmeid.use")) {
            $id = $this->getInventory()->getItemInHand()->getID();
            $meta = $this->getInventory()->getItemInHand()->getDamage();
            $sender->sendMessage($prefix . "You are holding item ID: §7" . $id . ":" . $meta);
        }
    }
}

Plugin 2 – EconomyChat:
I tried breaking wood, but it doesn't add money. Plus, it doesn't take away money too, when using the /pm command:

PHP:

<?php
namespace WinterBuild\EconomyChat;

use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\command\CommandExecutor;
use pocketmine\command\CommandMap;
use pocketmine\event\Listener;
use pocketmine\Player;
use pocketmine\plugin\PluginBase;
use pocketmine\Server;
use pocketmine\utils\TextFormat;
use pocketmine\utils\Config;
use pocketmine\permission\ServerOperator;
use pocketmine\event\player\PlayerChatEvent;
use pocketmine\event\player\PlayerJoinEvent;
use pocketmine\event\player\PlayerPreLoginEvent;
use pocketmine\command\ConsoleCommandSender;
use pocketmine\event\block\BlockBreakEvent;

class Main extends PluginBase implements Listener {
    public function onEnable() {
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
        $this->saveDefaultConfig();
    }

    public function onCommand(CommandSender $sender, Command $cmd, $label, array $args) {
    $money = 100;
    $plname = "§7[§e§lPM§r§7]§f ";
    $errortag = "§7[§c§lPM§r§7] ";
        if($cmd->getName() === "pm" || $cmd->getName() === "privatemsg") {
            if($args[0] === "about") {
                $sender->sendMessage($plname . "EconomyChat/PM by WinterBuild. Send private messages to players with in-game money.");
            }
            if($args[0] === "send") {
                if(isset($args[1])) {
                    if(isset($args[2])) {
                        if($money >= strlen($args[2])) {
                            $msg = $args[2];
                            $me = $sender->getName();
                            $money = $money - strlen($msg);
                            $tousr = $sender->getServer()->getPlayer($args[1]);
                            if($tousr instanceof Player) {
                                $usrtag = "§7[PM: Â§f§l" . $me . "§r§7->§f§l" . $tousr->getName() . "§r§7] Â§f";
                                $sender->sendMessage($usrtag . $msg);
                                $tousr->sendMessage($usrtag . $msg);
                            }
                            else {
                                $sender->sendMessage($errortag . "There's no player with that name or is offline!");
                            }
                        }
                        else {
                            $sender->sendMessage($errortag . "You don't have enough money! Your money:" . $money);
                        }
                    }
                    else {
                            $sender->sendMessage(§errortag . "You cannot send an empty message!");
                    }
                }
                else {
                        $sender->sendMessage($errortag . "How to use: /pm send <player> <private-message>");
                }
            }
            if($args[0] === "money") {
                $sender->sendMessage($plname . "You have $" . $money . ".");
            }
            if(!isset($args[0]) || $args[0] === "help") {
                $tutorial = $this->getConfig()->get("HowToGetMoney");
                $sender->sendMessage("§7---------- Â§e§lPM Commands Â§r§7----------");
                $sender->sendMessage("§7§lEconomyChat PM§r§f - Send PrivateMessages (PMs) to other players with in-game money.");
                $sender->sendMessage($tutorial);
                $sender->sendMessage("§7/pm help" . " Â§f- Show all EconomyChat/PM commands.");
                $sender->sendMessage("§7/pm about" . " Â§f- About EconomyChat/PM");
                $sender->sendMessage("§7/pm send <player> <message>" . " Â§f- Send a PrivateMessage (PM) to a player.");
                $sender->sendMessage("§7/pm money" . " Â§f- See how much money you have.");
                $sender->sendMessage("§7-------------------------------------");
            }
        }
    }
    public function onBreak(BlockBreakEvent $event) {
        $blockbreak = $this->getConfig()->get("BlockBreak");
        $moneyget = $this->getConfig()->get("BreakMoney");
        if($event->getBlock()->getId() === $blockbreak) {
            $money = $money + $moneyget;
        }
    }
}

 

If you have multiple plugins using the same namespace, the plugins will interfere with each other when they are constructed.

PHP:

<?php

namespace WinterBuild7;

use pocketmine\plugin\PluginBase;
use pocketmine\Player;
use pocketmine\Server;
use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\command\CommandExecutor;
use pocketmine\utils\TextFormat;

class Main extends PluginBase {
  
    public $prefix = "§7[§f§lTellMeID§r§7]§f ";
  
    public function onEnable() {
        $this->getLogger()->info($prefix . "by WinterBuild7 was loaded!");
    }
  
    public function onCommand(CommandSender $sender, Command $command, array $args) {
        if($command->getName() === "tellmeid" && $sender->hasPermission("tellmeid.info")) {
            $sender->sendMessage($prefix . "TellMeID by WinterBuild7. Tells you the item in hand.");
        }
        if($command->getName() === "hand" && $sender instanceof Player && $sender->hasPermission("tellmeid.use")) { //make sure the sender is a player
            $id = $sender->getInventory()->getItemInHand()->getID(); //use $sender instead of main class
            $meta = $sender->getInventory()->getItemInHand()->getDamage(); //use $sender instead of main class
            $sender->sendMessage($prefix . "You are holding item ID: §7" . $id . ":" . $meta);
        }
    }
}

 

How can I change and fix this?

 

when you are setting the amount of money for each player, set the data to a global array using the player names as the keys

 

How? I never did that before. Code? I know how to use array and keys, but I don't know how to make it really.

 

something like this:

PHP:

$this->money[$playerName] = $money;

 

But I still need a code that adds to player to the array.

 

what do you mean?

 

Um, I don't unerstand. What will the whole code be? Do I need to construct?

 

you are trying to make an economy system correct? You need a way to track each player's money amount. You need to use an array.

 

Yes. But how can I add the player's name to the array, plus, how much money this player has? Also, do I need to add those?

 

use the code I gave you. the variable names should be self explanatory.

 

Where do I need to add that?
Plus, do I still need to add any more code except that piece?

 

You need to learn more about how to program before asking these questions on this forum. We are here to help with PMMP API, not generic php.

 

For the plugin no. 1, I did all that, but no changes. 90% of all plugins not loading.

 

You must be getting errors. $money is undefined in your BlockBreakEvent handler.

 

I gave up with my plugins, don't need help with that anymore. But I'm still wondering why my plugin no. 1 isn't working.
Plus, if any more replies here, then admins, please move this to 'Development', I'll be more careful with forum categories.
