PHP - 将foreach循环重写为for循环以获得计数器

Question

I'm trying to rewrite two foreach loops as for loops so that I am able to stop them at 3. Here is the first and simple loop's original:

<?php foreach ($marketing[0]['values'] as $company) { ?>
            <tr>
              <td><?php echo $company['label']; ?></td>
              <td><?php echo $company['value']; ?></td>
            </tr>
          <?php } ?>

Here is my attempted re-write:

 <?php 
        for($i = 0; $i < 4; ++$i) { 
        $company = $marketing[0][$i]['values']; 
      ?>
        <tr>
          <td><?php echo $company['label']; ?></td>
          <td><?php echo $company['value']; ?></td>
        </tr>            
      <?php } ?>

Here is the second and slightly more complicated foreach loop that I haven't attempted yet.

<?php foreach ($sales as $sale) { ?>
          <tr>
            <td><?php echo $sale['key']; ?></td>
            <td>
              <?php 
                foreach ($sale['values'] as $values) {
                  if ($values['x'] == $currentTeam) {
                    echo $values['y'];
                  }
                }                 
              ?>
            </td>
          </tr>
          <?php } ?>

You can always use break. http://php.net/manual/en/control-structures.break.php

<?php $counter = 0; ?>
<?php foreach ($marketing[0]['values'] as $company) { ?>
    <?php if ($counter == $maxLimit) break; ?>
    <tr>
        <td><?php echo $company['label']; ?></td>
        <td><?php echo $company['value']; ?></td>
    </tr>
    <?php $counter++; ?>
<?php } ?>
