Example Usage

include 'TinyLog.php';

$log_path = __DIR__ . '\logs';
$tiny_log = new TinyLog();
$tiny_log->setLogStorePath($log_path);

for ($i = 0; $i <= 10; $i++) {

    $log_message = array(
        "name" => "Tom $i",
        "lname" => "Cat $i"
    );

    $tiny_log->debug("Something", $log_message);
    $tiny_log->info("Something", $log_message);
    $tiny_log->error("Something", $log_message);

}

<?php

session_start();


include 'TinyLog.php';
include 'FileReader.php';

$log_path = __DIR__ . '/logs';

$tiny_log = new TinyLog\TinyLog();
$fileReader = new TinyLog\FileReader();
$tiny_log->setLogStorePath($log_path);

if (isset($_SESSION['log_files']) === false) {
    $log_files = $tiny_log->readLogs(\TinyLog\TinyLog::TYPE_ERROR);
} else {
    $log_files = $_SESSION['log_files'];
}

$log_files = $tiny_log->readLogs(\TinyLog\TinyLog::TYPE_ERROR);

//var_dump($log_files);
