如何在PHP代码中添加PHP代码？

Question

例如(在我的例子中)这里是一些代码,

<?php
    woo_post_inside_before();   
    if ( $woo_options['woo_post_content'] != 'content' AND !is_singular() )
        woo_image( 'width='.$woo_options['woo_thumb_w'].'&height='.$woo_options['woo_thumb_h'].'&class=thumbnail '.$woo_options['woo_thumb_align'] );
    the_title( $title_before, $title_after );
    woo_post_meta();
?>

现在我想放置以下PHP代码,以便在之前输出woo_post_meta();:

    <?php if (is_single()) : ?>
    <div class="testb"><img src="http://whatthenerd.com/what/wp-content/themes/canvas/300.jpg" alt="test Ad" /></div>
    <?php endif; ?>

如果我必须按字面意思显示它,代码将是这样的:

<?php
    woo_post_inside_before();   
    if ( $woo_options['woo_post_content'] != 'content' AND !is_singular() )
        woo_image( 'width='.$woo_options['woo_thumb_w'].'&height='.$woo_options['woo_thumb_h'].'&class=thumbnail '.$woo_options['woo_thumb_align'] );
    the_title( $title_before, $title_after );

    <?php if (is_single()) : ?>
    <div class="testthisad"><img src="http://whatthenerd.com/what/wp-content/themes/canvas/300.jpg" alt="test Ad" /></div>
    <?php endif; ?>

    woo_post_meta();
?>

显然,这不是正确的做法.那么,我该怎么做？

只需要一组标签:

<?php
    woo_post_inside_before();   
    if ( $woo_options['woo_post_content'] != 'content' AND !is_singular() )
        woo_image( 'width='.$woo_options['woo_thumb_w'].'&height='.$woo_options['woo_thumb_h'].'&class=thumbnail '.$woo_options['woo_thumb_align'] );
    the_title( $title_before, $title_after );

    if (is_single()){
?>
    <div class="testthisad"><img src="http://whatthenerd.com/what/wp-content/themes/canvas/300.jpg" alt="test Ad" /></div>
<?php
    }

    woo_post_meta();
?>
