在插件的主PHP文件中：

$plugin_data = get_plugin_data( __FILE__ );
$plugin_name = $plugin_data[\'Name\'];

这将为您提供插件文件夹名称，无论文件位于何处，也不必知道插件的目录结构。

$plugin_folder_name = reset(explode(\'/\', str_replace(WP_PLUGIN_DIR . \'/\', \'\', __DIR__)));

// Get the relative path to current file from plugin root
$file_path_from_plugin_root = str_replace(WP_PLUGIN_DIR . \'/\', \'\', __DIR__);

// Explode the path into an array
$path_array = explode(\'/\', $file_path_from_plugin_root);

// Plugin folder is the first element
$plugin_folder_name = reset($path_array);
