Yes, you can use printf and sprintf in WordPress too!

something.php
<?php
// Dirty, easy to miss a ' or " or .
echo '<a href="' . get_permalink() . '" class="link">' . get_the_title() . '</a>';
// Clean, easier to read
printf( '<a href="%s" class="link">%s</a>', get_permalink(), get_the_title() );
// Almost as clean, and more secure, maybe a little paranoic :)
printf( '<a href="%s" class="link">%s</a>', esc_url( get_permalink() ), esc_html( get_the_title() ) );

@corvannoorloos it's up to you, but the second snippet looks cleaner to me, but I'd go slightly further:

function cor_canonical_link() {
    printf( "<link href='%s' rel='canonical' />\n", get_pagenum_link( get_query_var( 'paged' ) ) );
}

@kovshenin thank you! I wasn't aware of this use of get_query_var.

Personally I prefer to use double quotes on the href and rel, but this definitely gives me something to work with.
