准备做个wordpress的主题,结果看到了如下的语法: <div id="primary" class="content-area">
<main id="main" class="site-main" role="main">
<?php if ( have_posts() ) : ?>
<?php if ( is_home() && ! is_front_page() ) : ?>
<header>
<h1 class="page-title screen-reader-text"><?php single_post_title(); ?></h1>
</header>
<?php endif; ?>
<?php
// Start the loop.
while ( have_posts() ) : the_post();
/*
* Include the Post-Format-specific template for the content.
* If you want to override this in a child theme, then include a file
* called content-___.php (where ___ is the Post Format name) and that will be used instead.
*/
get_template_part( 'content', get_post_format() );
// End the loop.
endwhile;
// Previous/next page navigation.
the_posts_pagination( array(
'prev_text' => __( 'Previous page', 'twentyfifteen' ),
'next_text' => __( 'Next page', 'twentyfifteen' ),
'before_page_number' => '<span class="meta-nav screen-reader-text">' . __( 'Page', 'twentyfifteen' ) . ' </span>',
) );
// If no content, include the "No posts found" template.
else :
get_template_part( 'content', 'none' );
endif;
?>
</main><!-- .site-main -->
</div><!-- .content-area -->这才知道php是有不太常用的替代语法的: 据 http://www.jb51.net/article/23252.htm
PHP中那些语法有替代语法?
流程控制(包括if,while,forforeach,switch)这几个语句有替代语法。
替代语法的基本形式:
左花括号({)换成冒号(:),把右花括号(})分别换成 endif;,endwhile;,endfor;,endforeach; 以及 endswitch;
举个例子吧:
