We often see this insdie the WordPress templates:

while ( have_posts() ) : the_post();

Do you have any idea why not using braces or "curly brackets" {} for while loop? What is the gain?


According to the wordpress handbook on php coding standards, braces should be used for all blocks in the style shown below:

if ( condition ) {
} elseif ( condition2 && condition3 ) {
} else {

The use of braces means single-statement inline control structures are prohibited so it's better to use the alternative syntax for control structures (e.g. if/endif, while/endwhile) in this scenario, especially in template files where PHP code is embedded within HTML:

<?php if ( have_posts() ) : ?>
    <div class="hfeed">
        <?php while ( have_posts() ) : the_post(); ?>
            <article id="post-<?php the_ID() ?>" class="<?php post_class() ?>">
                <!-- ... -->
        <?php endwhile; ?>
<?php endif; ?>

    And please don't mix this with wordpress.stackexchange.com/questions/220682/…, after a check I saw your answer is almost identical with one answer from there. – prosti Jan 5 '17 at 23:31
  • I just quoted the documentation mostly, the key point being the prohibition of single-statement inline control structures – Tunji Jan 5 '17 at 23:32
  • I see now sorry, so you don't see any gain? @TunjiAyoola – prosti Jan 6 '17 at 8:10

It's just another way of writing it, mostly a stylistic choice. I use while loops with curly brackets, and find while : endwhile very hard to read.

Edit: previously asked here. tl;dr: same answer.
