    ["description"]=> "Another efficient search engine popular in Russia"
  }
}

how can i select only this items from array what have "tid" = 1?

Answer 1

$filteredArray = array();

for($i = 0, $end = count($array);$i < $end;i++)
{ 

    if($array[$i]["tid"] === "1") 
    {
       $filderedArray[] = $array[$i];
    }
 }

That way $filteredArray will contain solely the items with tid 1;
