Read contents of multiple. txt’s files from a given folder

Question

I have this code that reads a file created by Netscape HTTP Cookie File, however I could only use the script and read the file of the user who is with the session username open, I need to list all the TXTS and read them all without exception.

NOTE: the files have different names:

<?php

require_once getcwd() . '/modules/config.php';

$username = null;

if (isset($_SESSION['username'])) {
    $username = $_SESSION['username'];
}

$pointer = fopen(getcwd() . '/cookies/' . $username . '.txt', 'r');

while (!feof($pointer)) {
    $row = fgets($pointer);
}

fclose($pointer);

How to read all files with different names other than the file with the name created in the session ?

EDITED

In the comments Anderson cited the use of function glob(), I was able to read all the files with this code.

foreach (glob(getcwd() . '/cookies/*.txt') as $file) {
    $pointer = fopen($file, 'r');
    while (!feof($pointer)) {
        $row[] = fgets($pointer);
    }
}

var_dump($row);

However it contains unnecessary lines in the file, I need to get only the cookies, look what comes back:

I just need the cookies, you know what I mean?

For commenting, you want to pick up only the lines that contain the values of _twitter_sess, ct0 and auth_token. You can store these values in a list:

$tokens = ['_twitter_sess', 'ct0', 'auth_token'];

And check which lines have at least one of these values:

foreach (glob(getcwd() . '/cookies/*.txt') as $file) {
    $pointer = fopen($file, 'r');
    while (!feof($pointer)) {
        $line = fgets($pointer);

        foreach ($tokens as $token) {
            if (strpos($line, $token) !== false) {
                $row[] = $line;
                break;
            }
        }
    }
}

Thus, the line in $pointer will only be added to the list if some token defined in $tokens is found on the line. After that, you can use either regular expression or separate the line in the blanks to extract the desired value.
