Advanced Custom Fields [closed]

Question

I am trying to call a field and it's heading on a post type. I want to call headings only if there is content in the field. I'm really new to PHP and am unsure how it all works. I have added the following script in content-single.php

 <?php $field = get_field('introduction'); 
    if(!empty && is_array){
        ?>
         <div class="sc-project-type">
            <h4>Introduction:</h4>
            <?php //$terms = get_the_terms($post->ID, 'project_type');
                echo '$field'; ?>
         </div>
        <?php } ?>

This brakes produces nothing. If I just , it works, but I want to add lots of fields that won't always be visible. Any ideas?

OK, after playing for a while, I solved my issue with the following code:

        <?php $field = get_field('introduction');
    if(!empty ($field)){
        ?>
         <div class="sc-project-type">
            <h4>Introduction:</h4>
            <?php echo ($field); ?>
         </div>
        <?php } ?>
