Add a value to an array

I have a array on my yaml...

Code:

array:
- blabla1
- blabla2
- blabla3

How I can add a value to it?
I want add blabla4.

EX:

Code:

array: 
 - blabla1
 - blabla2
 - blabla3
 - blabla4

Try it:

PHP:

$array = $this->getConfig()->get('array');
$new_array = $array;
$new_array[] = 'blabla4';
$this->getConfig()->set('array', $new_array);
$this->getConfig()->save();


Thanks! Now I have another small problem... how I can delete blabla2 (for example)?

PHP:

$array = $this->getConfig()->get('array'); // values: blabla1, blabla2, blabla3, blabla4
$for_remove = 'blabla2';
$new_array = [];
foreach($array as $value) {
    if($value != $for_remove) {
        $new_array[] = $value;
    }
}
$this->getConfig()->set('array', $new_array);
$this->getConfig()->save();


PHP:

$new = "blabla2";
$array = $this->getConfig()->get("array");
for ($i = 0; $i <= count($array); $i++) {
if ($array[$i] === $new) {
     unset($array[$i]);
}
}sort($array);
$this->getConfig()->setNested("array", $array);
$this->getConfig()->save();

don't forget:

and count() will return 4

Or simply use array_search() + unset()
Or just make the data be in the keys instead of the values.

It works! But I have a problem...
I do a command, and it works the first time...
But the second time it removes the first time value and add the new value.

I mean:
/aw add pedro

And now the yaml shows:

Code:

ex:
 - ex
 - ex
 - pedro

But if execute it another time (this time /aw add dro), the yaml shows:

Code:

ex:
 - ex
 - ex
 - dro

Show full code.

RemovePlayer not working.
AddPlayer working bad (I said you the problem :'] )

PHP:

    private function addPlayer($playerName){
            $newPlayer = $this->allowJoinList;
            $newPlayer[] = $playerName;
            $this->getConfig()->set("AllowJoin", $newPlayer);
            $this->getConfig()->save();
    }

    private function removePlayer($playerName){
        for ($i = 0; $i <= count($this->allowJoinList); $i++) {
            if ($this->allowJoinList[$i] === $playerName) {
                unset($this->allowJoinList[$i]);
            }
        }sort($this->allowJoinList);
        $this->getConfig()->setNested("AllowJoin",$this->allowJoinList);
        $this->getConfig()->save();
    }

Commands:

PHP:

    # Commands

    public function OnCommand(CommandSender $sender, Command $command, $label, array $args){
        if($command->getName() == "aw" and $sender->hasPermission("commands.alwaysjoin")){
            switch(strtolower($args[0])){
                case "add":
                        if (isset($args[1])) {
                            $this->addPlayer($args[1]);
                            $sender->sendMessage("Added " . $args[1] . " to AlwaysJoin :)");
                        } else {
                            $sender->sendMessage("Usage: /aw <add/remove> [player]");
                        }

                break;
                case "remove":
                    if(isset($args[1])) {
                        $this->removePlayer($args[1]);
                    }
                    else{
                        $sender->sendMessage("Usage: /aw <add/remove> [player]");
                    }
                break;
                default:
                    $sender->sendMessage("Usage: /aw <add/remove> [player]");
                    break;
            }
        }
    }
}

for remove try my code:

PHP:

$array = $this->getConfig()->get('array'); // values: blabla1, blabla2, blabla3, blabla4
$for_remove = 'blabla2';
$new_array = [];
foreach($array as $value) {
    if($value != $for_remove) {
        $new_array[] = $value;
    }
}
$this->getConfig()->set('array', $new_array);
$this->getConfig()->save();


and why addPlayer working bad? More info, please.

When I run the command two times, the first time it works fine, but the second it only delete the first line...

Use array_search() >.<

$this->getConfig()->reload();

Bumping threads is cool..
