[Plugin: Visual Composer] Get php code of an element

Hi,

I use visual composer and I need the php code of a layout. For example, if I have:

[vc_column width=”1/3″][kleo_gap size=”65px”][vc_posts_grid loop=”size:1|order_by:date|order:ASC|post_type:blog|by_id:11659″ columns=”1″ show_excerpt=”no” show_footer=”no”][kleo_gap size=”50px”][/vc_column]

Where can I find the equivalent in php ? I need to insert it in custom tabs, so I can’t use these shortcodes.

Thanks for your time and help
