How to display field label in record view

I use custom template and this is how I add field in template file:

<?php if(isset($item->fields_by_key[$params->get('tmpl_params.field_othertitles')])): ?>
    <div class="field-othertitles">
        <?php echo $item->fields_by_key[$params->get('tmpl_params.field_othertitles')]->result; ?>
    </div>
<?php endif; ?>

I have 12 fields added using same type of code. How can I add label to each field so that it will look at field parameter if label needs to be shown or not and breakable or not.

<?php if($field->params->get('core.show_lable') > 1):?>
    <label id="<?php echo $field->id;?>-lbl">
        <?php echo $field->label; ?>
    </label>
    <?php if($field->params->get('core.label_break') > 1):?>
    <?php endif;?>
<?php endif;?>

this code is from default tempalte but it does not work because I am using key-s to display fields how I guess. What I need to edit in this code? I was not able to find info in documentation.
