Just Google it

Ok, so i took initiative and searched it up. Is there specific code for pocketmine or am i doing this wrong

PHP:

public function init(){
     $this->api->console->register("chatsend","Sends a message to a user", array($this, "send"));
     $this->api->ban->cmdwhitelist("chatsend");
   }

public function send($cmd, $args, $issuer){
    $myFile = "testFile.txt";
    $fh = fopen($myFile, 'r');
    $theData = fread($fh, 5);
    $username = $issuer->username;
    $this->api->chat->sendTo(false, $theData, $username);
  }

  public function __destruct(){
  }

Yes, you need to read the file in binary. You could make this easier and just do it in json or yaml.

PHP:

 public function init(){
  
    $this->api->console->register("chatsend","Sends a message to a user", array($this, "send"));
    $this->api->ban->cmdwhitelist("chatsend");
  }

  public function send($cmd, $args, $issuer){
    $arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);
    $username = $issuer->username;
    $this->api->chat->sendTo(false, json_encode($arr), $username);
  }

  public function __destruct(){
  }

doesnt work!!!

just do:

Code:

 
console(json_encode($arr));

ok, so it works. So how do i save this in a file format, then recall it at a later time​

Sorry, but I'm not going to develop the plugin for you

sorry, but theres not a lot of info on plugin making....

Mini-Wiki

this is very helpful

YAY I FOUND OUT!!!!!

PHP:

 public function init(){
    $this->readConfig();
  }
public function readConfig(){
        $arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);
        $this->path = $this->api->plugin->createConfig($this, array((json_encode($arr))));
        $this->config = $this->api->plugin->readYAML($this->path."config.yml");
  }

You are encoding a json file and reading a YAML file, Wrong

Then how do I do it?

Here are a repository of my plugins. You just see how I do

thank you!

Sounds (yes, really sounds) like reading binary is faster than reading YAML and convert it using Spyc. But the main thread is the I/O streams
