Meddling with variable variables in PHP

I am trying to use variable variables. By using $type in a foreach loop, I would like to get the value of $week['one'] and $month['one'].

    $types = array(
        'week',
        'month'
    );

    $week = array(
        'one' => 1.2,
        'two' => 0.13,
    );

    $month = array(
        'one' => 1.2,
        'two' => 0.13,
    );

Methods I've tried without success:

    <?php foreach ($types as $type): ?>
            <?= $$type['one']; ?><br />
            <?= $$type['two']; ?><br />
    <?php endforeach; ?>

    <?php foreach ($types as $type): ?>
            <?= ${$type}['one']; ?><br />
            <?= ${$type}['two']; ?><br />
    <?php endforeach; ?>

    <?php foreach ($types as $type): ?>
            <?= $($type)['one']; ?><br />
            <?= $($type)['two']; ?><br />
    <?php endforeach; ?>

Everything seems to resul in syntax errors. Am I using the wrong syntax?

Use this variant:

<?php foreach ($types as $type): ?>
        <?= ${$type}['one']; ?><br />
        <?= ${$type}['two']; ?><br />
<?php endforeach; ?>
