https://stackoverflow.com/questions/17224798/how-to-use-php-opcache

inode detect directories

du --inodes -S | sort -rh | sed -n \
        '1,50{/^.\{71\}/s/^\(.\{30\}\).*\(.\{37\}\)$/\1...\2/;p}'

arba tiesiog suskaiciuoti failus aplankuose:

Detecting the HTTP method

$method = $_SERVER['REQUEST_METHOD']
if ($method == 'POST') {
    // Method is POST
} elseif ($method == 'GET') {
    // Method is GET
} elseif ($method == 'PUT') {
    // Method is PUT
} elseif ($method == 'DELETE') {
    // Method is DELETE
} else {
    // Method unknown
}

Way to use PUT data from PHP:
$method = $_SERVER['REQUEST_METHOD'];
if ('PUT' === $method) {
    parse_str(file_get_contents('php://input'), $_PUT);
    var_dump($_PUT); //$_PUT contains put fields 
}
