我正在建一张表，里面有一些项目。我不明白的是：

当我键入时<td> <?php custom_get_terms(\'landschapspakket\');?> </td>, 它呼应了custom_get_terms(\'landschapspakket\').

我想做的是在它上面使用一些条件逻辑来查看它有哪些值，然后对其进行回应。相反，它甚至在我键入echo之前就输出了它。这和环路有关吗？我如何避免这种情况？

<table>

            <tr>
                <th>Landschapspakket</th>
                <th>Be nr.</th>
                <th>Gebiedscode</th>
                <th>Gebruiksrecht</th>
                <th>Grond</th>
                <th>Aantal</th>
                <th></th>
            </tr>

            <?php $query = new WP_Query(array(\'post_type\' => $current_posttype, \'posts_per_page\' =>\'-1\', \'post_status\' => array(\'publish\', \'pending\', \'draft\', \'private\'/* , \'trash\' */) ) ); ?>

            <?php if ($query->have_posts()) : while ($query->have_posts()) : $query->the_post(); ?>

            <tr>
                <td><?php custom_get_terms(\'landschapspakket\');?></td>
                <td><?php custom_get_terms(\'beheerseenheidnummer\');?></td>
                <td><?php custom_get_terms(\'gebiedscode\');?></td>

                <td><?php custom_get_terms(\'grond\');?></td>
                <td><?php custom_get_terms(\'stuks\');?></td>

                <?php $edit_post = add_query_arg(\'post\', get_the_ID(), get_permalink(429 + $_POST[\'_wp_http_referer\'])); ?>

                <td>
                    <a href="<?php echo $edit_post; ?>">Bewerk</a>

                    <?php if( !(get_post_status() == \'trash\') ) : ?>

                        <a onclick="return confirm(\'Weet je zeker dat je <?php echo get_the_title() ?> wilt verwijderen?\')"href="<?php echo get_delete_post_link( get_the_ID() ); ?>">Verwijder</a>

                    <?php endif; ?>
                </td>
            </tr>

        <?php endwhile; endif; ?>

        </table>

function custom_get_terms($taxonomy) {

    // Get terms for post
     $terms = get_the_terms( $post->ID , $taxonomy );

     if ( $terms != null ){
            foreach( $terms as $term ) {

              unset($term);
            } 
    }
