Component Jea Joomla

Question

I have a PHP code inside a real estate component I’m using.

<fieldset>
    <legend><?php echo JText::_('COM_JEA_LOCALIZATION')?></legend>
    <?php foreach ($this->form->getFieldset('localization') as $field): ?>
      <div class="formelm"><?php echo $field->label . "\n" . $field->input ?></div>
    <?php endforeach ?>
  </fieldset>

This Code causes the html structure to show one with several and inside each one a label and an input. They would know just by looking at the code to have a basis of what goes on behind?
