Checking .txt files with getimagesize ()

Question

I getimagesize() uploaded by users with getimagesize() This is how:

 $imageinfo = getimagesize($file['tmp_name']); if($imageinfo['mime'] != 'image/gif' && $imageinfo['mime'] != 'image/jpeg' && $imageinfo['mime'] != 'image/png') { $data['error'] = 'Ошибка загрузки. Допустимые форматы: .jpeg .gif .png'; echo json_encode( $data ); exit; } else { list($width, $height) = getimagesize($file['tmp_name']); if ($width < $minWidth || $height < $minHeight || $height > $maxHeight || $width > $maxWidth){ $data['error'] = 'Изображение не может быть меньше '.$minWidth.' и больше '.$maxWidth.' пикселей <br> по одной из сторон. Пожалуйста выберите другое фото.'; echo json_encode( $data ); exit; } }

That is a check for mime types. Everything works perfectly with different formats, but when users load a .txt file instead of images, the server issues 500 (Internal Server Error) with the words LOG.error: exception 'ErrorException' with message 'getimagesize(): Read error!

Tried to do so:

 try {getimagesize($file['tmp_name']);} catch (Exception $e) { } if ($e === FALSE) { //ERROR }

Did not help. How to do it so that in case of an error of execution of getimagesize () there was not a 500 error, but a response in the form echo json_encode( $error ); ?

And, can knowledgeable people tell ... What is so special about the .txt format ??

Try using the @ operator :

 if ($imageinfo = @getimagesize($file['tmp_name'])) { //...ваш код } else { //выводим json с ошибкой }

I hope there will be no conflicts with the operators ... I'll try to accomplish my goal!
