说明（Description）

其工作方式与_title（）类似，但参数可以是字符串或数组。有关$args参数中可以重写的内容，请参阅函数。显示之前的标题将删除标记，并在传递给用户或显示之前使用esc_attr（）。默认情况下，与_title（）一样，显示标题。

源码（Source）

/**
 * Sanitize the current title when retrieving or displaying.
 *
 * Works like {@link the_title()}, except the parameters can be in a string or
 * an array. See the function for what can be override in the $args parameter.
 *
 * The title before it is displayed will have the tags stripped and {@link
 * esc_attr()} before it is passed to the user or displayed. The default
 * as with {@link the_title()}, is to display the title.
 *
 * @since 2.3.0
 *
 * @param string|array $args {
 *     Title attribute arguments. Optional.
 *
 *     @type string  $before Markup to prepend to the title. Default empty.
 *     @type string  $after  Markup to append to the title. Default empty.
 *     @type bool    $echo   Whether to echo or return the title. Default true for echo.
 *     @type WP_Post $post   Current post object to retrieve the title for.
 * }
 * @return string|void String when echo is false.
