Player TagName with Color

Hello Guys, i wanted to use some experimental options, and as the title said, im trying to change the player tag color when they execute the command, but... i investigated already and it does not gives me any results!! help please!!

$player->setNameTag("§colorcode blah blah blah");

PHP:

$player = //Declare player, yada yada yada;
$player->setNameTag("§a$player"); //§a is green, change it to something else if you would like.


Cant be like:

PHP:

$sender->setNameTag("§c$name");     ?

oh, man, it says that i don't have a variable called "$player" help!

$sender represents the command sender, and you can change $player to $name.

but, what do i need to establish on $player??

bro? because its asking me to define player

If you want $player as the name,

PHP:

$player = $sender->getName();

Learn PHP. You are just blindly copying code that people give you, without knowing how it works.

Actually, yeah, i make my code, this is not just PHP, this is Pocketmine API, learn definitions men, good luck

You make your own codes? XD

If you really know PHP, you should know that a variable cannot be defined from nothingness. You didn't define $player. You can't blame it on the API, because superglobals only exist in PHP for the default ones ($_REQUEST, $_GET, $_POST, $GLOBALS, $_SESSION, $_FILES).
Please learn PHP and learn the basics about variables.

But he said he knew how to make codes... XD

PHP:

public function onCommand(CommandSender $sender, Command $command, $label, array $args){
if(strtolower($command->getName()) === 'nametag'){
if(isset($args[0])){
switch(strtolower($args[0])){
case "blue"
case "bl":
$sender->setNameTag(TextFormat::BLUE.$sender->getDisplayName());
$sender->sendMessage('Your name tag is now blue');
}
}
}
}


Why not use getNameTag instead? And TextFormat::clean() if you want.

I'll keep that in mind.
