[Plugin: Qtranslate] Qtranslate doesnt work in php

Hello guys, i am having problems with qtranslate in php.

Here is my code that i added in this line:

$output .= '</h2> <p>'. trim(strip_tags(substr(qtrans_use(qtrans_getLanguage(), $news->post_content),0,500))) .'... <a href="'. get_blog_permalink($news->blog_id, $news->ID ).'"><?php _e("<!--:en-->english text<!--:--><!--:es-->spanish text<!--:-->"); ?></a></p> </div></li>';
