How to correctly compose a vk search query?

Question

PHP

Still, I regretted the Vkontakte API and began to use it. After long painful rewriting of the code, I was able to implement music search through VK on the site.
It's time to search for the video. Everything works on the same principle, only the request is different.
Here is the request:

$xml_response = Send_Post("https://api.vk.com/method/video.search.xml?access_token=$a_token&q=$fquery&count=1&sort=2&adult=0&v=5.24"); 

$parse = simplexml_load_string($xml_response);

the same Curl method is used that was used for music (music search works)
But when you try to save the parse variable on the site, it returns empty.
Well, what is wrong with my request?

$a_token = вечный токен после авторизации, вытягиваю из куки
$fquery = переформированный запрос ( The Beatles => The+Beatles )
