wordpress - How to insert this php instruction into printf result? -

i new in php world , customizing wordpress template.

i have following function in php file:

function admired_posted_on() {     printf( __( '<span class="sep">posted on </span>                  <a href="%1$s" title="%2$s" rel="bookmark">                     <time class="entry-date" datetime="%3$s" pubdate>%4$s</time>                   </a>                   <span>blabla</span>                  <span class="by-author">                      <span class="sep"> bla</span>                      <span class="author vcard">                         <a class="url fn n" href="%5$s" title="%6$s" rel="author">%7$s</a>                      </span>                   </span>                  ', 'admired' ),      esc_url( get_permalink() ),     esc_attr( get_the_time() ),     esc_attr( get_the_date( 'c' ) ),     esc_html( get_the_date() ),     esc_url( get_author_posts_url( get_the_author_meta( 'id' ) ) ),     sprintf( esc_attr__( 'view posts %s', 'admired' ), get_the_author() ),     esc_html( get_the_author() )     );     } 

now, have insert inside printf body following php code blabla tag instead of "blabla" text. php code have insert:

<?php echo '(' . get_postviews(get_the_id()) . ')'; ?> 

if insert ithis row previous span tag go error.

the get_postviews(get_the_id()) return integer have show in span

someone can me?

if there single quotes ' in string enclosed single quotes have escape quotes. (note \'):

$string = '<span class="sep">posted on <?php echo \'(\' . get_postviews(get_the_id()) . \')\'; ?></span>... more content ....'; 

but in example following solution might simpler:

$string = '<span class="sep">posted on (<?php echo get_postviews(get_the_id()); ?>)</span>... more content ....';
