FYI, on windows, the vlaues for LOG_* "log-levels" are as followed:



<?php

namespace Test;



include 'vendor/autoload.php';



use Psr\Log\LogLevel;



$log_levels = array(

    LogLevel::EMERGENCY => LOG_EMERG,

    LogLevel::ALERT => LOG_ALERT,

    LogLevel::CRITICAL => LOG_CRIT,

    LogLevel::ERROR => LOG_ERR,

    LogLevel::WARNING => LOG_WARNING,

    LogLevel::NOTICE => LOG_NOTICE,

    LogLevel::INFO => LOG_INFO,

    LogLevel::DEBUG => LOG_DEBUG,

);



print_r($log_levels);

/*

prints:



Array

(

    [emergency] => 1

    [alert] => 1

    [critical] => 1

    [error] => 4

    [warning] => 5

    [notice] => 6

    [info] => 6

    [debug] => 6

)
