我有一段PHP代码，它查看了每篇文章，并显示了它在归档页面上列出的类别，但我想用逗号或空格来分隔它们。谢谢

      <?php if ( ! $jobs ) : ?>
            <tr>
                <td colspan="6"><?php _e( \'You do not have any active   listings.\', \'wp-job-manager\' ); ?></td>
            </tr>
        <?php else : ?>
            <?php foreach ( $jobs as $job ) : ?>
                <tr>
                    <?php foreach ( $job_dashboard_columns as $key => $column ) : ?>
                        <td class="<?php echo esc_attr( $key ); ?>">
                            <?php if (\'job_title\' === $key ) : ?>
                                <?php if ( $job->post_status == \'publish\' ) : ?>
                          <a href="<?php echo get_permalink( $job->ID ); ?>"><?php echo $job->post_title; ?></a><br> Job Status: 


<?php

$terms = wp_get_post_terms( $job->ID, \'job_listing_category\' ); 

foreach ( $terms as $term ) {
  echo $term->name;
} 
?>

<?php else : ?>

                          <?php echo $job->post_title; ?> <small>  (<?php the_job_status( $job ); ?>)</small>
                            <?php endif; ?>
