WordPress 获取主题样式表 style.css 注释里的信息

我们在 Style.css 中都会填入自己的主题信息，例如名称或版本号等，以便 WordPress 展现给用户。以下是WP官方 2014 主题的注释：

/*

Author: the WordPress team
Author URI: https://wordpress.org/
Description: In 2014, our default theme lets you create a responsive magazine website with a sleek, modern design. Feature your favorite homepage content in either a grid or a slider. Use the three widget areas to customize your website, and change your content's layout with a full-width page template and a contributor page to show off your authors.

从中可以看到主题名称、主题链接、作者、作者链接、版本等等信息。在 WordPress 3.4 以上的版本中，我们可以直接使用 wp_get_theme() 这个函数来获取这些信息。以下是一些简单的例子：

获取当前主题名字：

<?php
echo wp_get_theme();
?>

获取其它主题名字：

<?php
$my_theme = wp_get_theme( 'twentyten' );
if ( $my_theme->exists() )
	echo $my_theme;
?>

获取当前主题版本号：

<?php
$my_theme = wp_get_theme();
echo $my_theme->get( 'Name' ) . " is version " . $my_theme->get( 'Version' );
?>

显示当前主题作者的链接：

<?php
$my_theme = wp_get_theme();
echo $my_theme->get( 'AuthorURI' );
?>
