custom function

Hi! I want to write a custom function to check for English letters and automatically translate some csv fields (name and description) into Russian. To do this, I use Yandex API. Code verification on the availability of English letters fulfills well. Translation also works, but only if you specify the exact text you want to translate. How do I add {name[1]} instead of the exact text? Here is my code:

<?php
function is_english($name)
{
    if (strlen($name) != strlen(utf8_decode($name))) {       
 $yt_api_key = "my-secret-api"; 
$yt_lang = "en-ru"; 
$yt_text = "name"; 
$yt_link = "https://translate.yandex.net/api/v1.5/tr.json/translate?key=".$yt_api_key."&text=".$yt_text."&lang=".$yt_lang;
$result = file_get_contents($yt_link); 
$result = json_decode($result, true); 
$en_test = $result['text'][0];          
       echo  $en_test;				
    } else {
   echo $name;         
    }
}
?>

As me change string $yt_text = "name";to obtain there significance $name or obtain not empty echo $en_test?

If you need a Yandex API key for This, write where to send it.

Thank you in advance, very much waiting for an answer.

I apologize for my English, translated from Russian by Yandex API.
