Need Help with plugin

I am new to plugin dev and can not get my first plugin to work properly. I need help! .zip file included that contains the code for my plugin. I get this error when i use the .zip to phar converter by PeMapModder:

• Classpath
  • Inspection result: Passed
  • Info
    • Main class scanned: Tutorial\MainClass
    • Main class file found at src/Tutorial/MainClass.php

• Bad practice
  • Inspection result: Passed

• Syntax errors
  • Inspection result: Error
  • Errors
    • Could not open input file: /var/www/tmp/5/Tutorial
  • Info
    • 0 good PHP file(s) and 1 bad PHP file(s) found.
    • Checked with PHP 5.6.11-1+deb.sury.org~trusty+1
  Error is in bold print. Please help me I am new to plugin dev!

BTW any help would be greatly appreciated!

.zip file contains all code for the plugin besides, of course the Pocketmine source code.

whoops, i am too much confused working on too many things, sorry.

LOL i feel the same!

I will put a sign, of whoever helps me first, in my minecraft server

Run the server with the plugin and post the error.

I already have run it here is the crash dump:

use pocketmine\command\CommandSender;

Add that

to before onCommand ?

nevermind not paying attention

I will try this.

still get:

Syntax errors

• Inspection result: Error
• Errors
  • Could not open input file: /var/www/tmp/5/Tutorial
• Info
  • 0 good PHP file(s) and 1 bad PHP file(s) found.
  • Checked with PHP 5.6.11-1+deb.sury.org~trusty+1

when i compile it.
Will test on my server.

Looks like it worked! My server does not crash now! THANK YOU SO MUCH!!

DOES NOT WORK!! here is crash dump:

change: public function onCommand(pocketmine\command\CommandSender $sender, pocketmine\command\Command $command, $label, array $args)
To: public function onCommand(CommandSender $sender, Command $command, $label, array $args){

and add use pocketmine\command\CommandSender; under namespace

I already added the use pocketmine\command\CommandSender

and it is set as public function onCommand (CommandSender $sender, Command $command, $label, array $args) already

PHP:

<?php

namespace Tutorial;

use pocketmine\plugin\PluginBase;
use pocketmine\command\CommandSender;
use pocketmine\command\Command;
use pocketmine\utils\TextFormat as Color;
use pocketmine\Player;

class MainClass extends PluginBase{
  
    public function onEnable() {
        $this->getLogger()->info(Color::GREEN. "[HAW] HAW has been enabled");
    }
   
    public function onDisable() {
       
       $this->getLogger()->info(Color::GREEN. "[HAW] HAW has been enabled");
    }  
   
   
      public function onCommand(CommandSender $sender, Command $command, $label, array $args) {
          if($sender instanceof Player) {
            $name = $sender->getName();  
          if($strtolower($command->getName()) === "tutorial")
            if(count($args) < 1) {
              $sender->sendMessage(Color::GOLD. "[Server] Hello $name welcome to our server!") ;
              return;
            }
             else {
                $sender->sendMessage(Color::RED. "[Server] sorry $name this command doesn't need arguments") ;
              return;
            }
        }
        $sender->sendMessage(Color::RED. "[HAW] You must be a player to execute this command!") ;
              return;
    }
}
