如果您知道插件主文件的函数或类，可以使用Reflection API.

我的插件示例T5 Taxonomy Location

add_action( \'plugins_loaded\', function()
{
    $class = \'T5_Taxonomy_Location\';

    if ( ! class_exists( $class ) )
        return;

    add_action( \'admin_footer\', function() use ( $class )
    {
        $reflection = new ReflectionClass( $class );
        $file       = $reflection->getFileName();
        $data       = get_plugin_data( $file );

        print \'<pre>$data = \' . esc_html( var_export( $data, TRUE ) ) . \'</pre>\';
    });
});

结果

$data = array (
  \'Name\' => \'T5 Taxonomy Location\',
  \'PluginURI\' => \'https://github.com/toscho/t5-taxonomy-location\',
  \'Version\' => \'2012.09.11\',

)
