$file = 'file.csv';

$line = file($file);

$arr = [];

foreach ($line as $k => $v) {
    $arr[] = explode(';', trim($v));
}

$days = ['пн', 'вт', 'ср', 'чт', 'пт', 'сб', 'вс'];


$result = [];

foreach ($arr as $k => $value) {
    if ($k > 1) {
        $result[array_shift($value)] = array_combine($days, array_chunk($value, 24));
    }
}

echo '<pre>' . print_r($result, true) . '</pre>';
