关联数组中表达式的字符串插值

Question

我有这样的定义：

define('LIBRARIES_URI', get_template_directory_uri() . '/libraries/');

现在，我有一个关联数组，例如：

array( 'name' => 'superfish-css', 'path' => LIBRARIES_URI .'superfish/css/superfish.css', 'type' => 'style' )

但是，路径不正确，这给了我一个错误，因为我猜有一个表达式。我尝试了各种东西，比如双引号之类的东西，但如果没有外部变量，我似乎无法正确处理。有没有办法正确插值？

完整示例：

define('LIBRARIES_PATH', TEMPLATEPATH . '/libraries/');


class Kosmos
{

  private static $inclusions = array(

    array( 'name' => 'style.css', 'path' => "get_bloginfo('stylesheet_url')", 'type' => 'style' ),
    array( 'name' => 'jquery', 'path' => '', 'type' => 'script' ),
    array( 'name' => 'jquery-ui-core', 'path' => '', 'type' => 'script' ),
    array( 'name' => 'jquery-ui-tabs', 'path' => '', 'type' => 'script' ),
    array( 'name' => 'superfish-css', 'path' => LIBRARIES_URI .'superfish/css/superfish.css', 'type' => 'style' ),
    array( 'name' => 'superfish-js', 'path' => "LIBRARIES_URI . 'superfish/js/superfish.js'", 'type' => 'script', 'dep' => array('jquery') ),
    array( 'name' => 'superfish-hover', 'path' => "LIBRARIES_URI . 'superfish/js/hoverIntent.js'", 'type' => 'script', 'dep' => array('jquery') ),
    array( 'name' => 'jquery-color', 'path' => "LIBRARIES_URI . 'horizontalMenu/jquery.color-RGBa-patch.js'", 'type' => 'script' ),

    /* admin */

    array( 'name' => 'admin-css', 'path' => "ADMIN_CSS_URI . 'admin.css'", 'type' => 'admin-style' ),
    array( 'name' => 'tabs-js', 'path' => "LIBRARIES_URI . 'tabs/tabs.js'", 'type' => 'admin-script' )

  );

  private static $admin_inclusions = array();

  public function inclusions() {
    return self::$inclusions;
  }

  public function admin_inclusions() {
    return self::$admin_inclusions;
  }  


}

类属性声明可能不包含表达式，只能包含文字/常量值。

将你的赋值移到构造函数中。
