Translate data from API in in template with an an other API - twig

Question

im doing a package tracker with PHP / TWIG , and would like to translate results in an other language, so i have a google translate APi
in my twig file i have this :
{% for item in item.origin_info.trackinfo %}
<div class="status-{{item.checkpoint_status}}">
<p> {{item.StatusDescription}}. </p>
<hr/>
{% endfor %}
And i would like to translate each {{ item.StatusDescription }}. Could you tell me how to do ?
my function to translate is :
function translation($str){
$url = "https://translate.googleapis.com/translate_a/single?client=gtx&sl=auto&tl=fr&dt=t&q=" . $str;
$result = file_get_contents($url);
$data = json_decode($result);
$traduction = $data[0][0][0];
$lang = $data[2];
return $traduction;
}

You could register a custom filter into twig which allows you to call global functions.
$twig = new \Twig\Environment($loader);
$twig->addFilter(new \Twig\TwigFilter('translate', 'translation'));
First parameter translate is what the filter will be called in twig, the second is your global function translation. You now can use this filter in any template, e.g.
{% for item in item.origin_info.trackinfo %}
<div class="status-{{item.checkpoint_status}}">
<p> {{ item.StatusDescription | translate }}. </p>
<hr/>
</div>
{% endfor %}
If you need more than one extra function, filter, test, ... you are better off with creating an extension. See documentation for more information on this.
