Get text in another text file

What am I doing wrong? I want to get the text from the txt file of another plugin, when I want to execute something on it, it says it is null, but why?

PHP:

@mkdir("/storage/emulated/0/PocketMine/plugins/VIP/", 0777, true);
   
$this->vips = new Config("/storage/emulated/PocketMine/plugins/VIP/" ."VIPS.txt", Config::ENUM, array());

To write text files, you do not use Config().
Instead, use

PHP:

$handle = fopen("the/directory/to/file.txt", "a");


and then, to write,

PHP:

fwrite($handle, $data); // $data is the text information.
fclose($handle);


If you want to get data from a text file, do file_get_contents().

Also, what is that useless '.' doing there? Combine the two strings..

Couldn't you also use file_put_contents();? And another way is file();

BTW, Opening it in w+ mode will overwrite all exisiting data with the new data being added, Use fopen("the/directory/to/file.txt", 'a'); to append new data to the file, just a heads up. And if you use the file_put_contents("the/directory/to/file.txt", $data); it will overwrite the existing data. So use the FILE_APPEND flag like so: file_put_contents("the/directory/to/file.txt", $data, FILE_APPEND);

Thanks to everyone, but I already found it out by myself, for these, who are interested:

PHP:

    $file = fopen("/storage/emulated/0/PocketMine/plugins/VIP/VIPS.txt" , "r");
                    $i = 0;
                    while (!feof($file)) {
                        $vips[] = fgets($file);
                    }
                    fclose($file);

foreach($vips as $vip){     
if($vip == $sender->getName()){ 
$sender->sendMessage("§aYou got the §6VIP §bkit§a.");

$sender->getInventory()->addItem(new Item(265, 0, 4)); 
$sender->getInventory()->addItem(new Item(269, 0, 1)); 
$sender->getInventory()->addItem(new Item(265, 0, 4)); 
$sender->getInventory()->addItem(new Item(354, 0, 1)); 
$sender->getInventory()->addItem(new Item(322, 0, 1)); 
}}     

My last question, how am I able to add text there on without deleting the current one?

Did you not read my earlier posts?

You're opening it in READ only mode...

Yeah I know, thanks fpr helping!

No worries!
