{
   echo "failed";

Answer 3

there is $http_response_header variable is being created in local scope that we can use it to check headers returned from server. Here is my implementation:

public function getData($url)
{
    try {
        $response = @file_get_contents($url);
        if (isset($http_response_header)) {
            if (!in_array('HTTP/1.1 200 OK', $http_response_header) &&
                !in_array('HTTP/1.0 200 OK', $http_response_header)) {
                throw new \Exception('Server did not return success header!');
            }
        }
        return $response;
    } catch (\Exception $ex) {
        throw new TransportException($ex->getMessage(), $ex->getCode(), $ex);
    }
}

Answer 4

Have you tried failing it on purpose to see what happens?

If it's an exception, just catch it and handle it...

try{
    //enter code to catch
}catch(Exception $ex){
    //Process the exception
}

If there is an error outputted by the function, just @ to hide the error and handle the incorrect output of $translate_feed or $translate manually.

You can try failing it on purpose by simply passing an invalid URI to file_get_contents and then forcefully feed non XML or invalid XML to simplexml_load_string to see what happens.

Answer 5

$translate_feed = file_get_contents('http://api.microsofttranslator.com/v2/Http.svc/Translate?appId=' . BING_APPID . '&text=' . urlencode($text) . '&from=en&to=' . $to_lan . '');
$result=$text;
if ($translate_feed) {
  $translate = simplexml_load_string($translate_feed);
  if (is_array($translate)) $result=$translate[0];
}
return $result;

Answer 6

You can do like this

if(@file_get_contents("yourFilePath.txt")){
     echo "success";
}
