I'm using Laravel 5.6 to let users upload their profile photo. On production, I've got some cases that returned error "Unable to init from given binary data." Got like 5 errors from the last 2,000 users uploads (0.25%). Pretty low, but these users are a more important users that I want to keep.
I use Dropzone as a frontend, and send only image data to Controller via Ajax Post.
Here is the Controller:
public function savePhotos(Request $request) {
if(!$_FILES["file"]["error"]){
$file = $request->file('file');
$ext = $file->getClientOriginalExtension();
$filename = Auth::user()->id . '.' . $ext;
$filePathAndName = 'uploaded/'.$filename;
Storage::disk('original_images')->put($filePathAndName, file_get_contents($file -> getRealPath()));
//generate thumbnail
try{
$img = Image::make(Storage::disk('original_images')->get($filePathAndName));
$img->orientate()->fit(200, 240);
$newImg=Image::canvas(200, 240, '#ffffff')->encode('jpg',75); //create a blank image 200x240 px with white background
$newImg->insert($img, 'center'); //paste resized img to new blank image
Storage::disk('thumb_images')->put($filePathAndName, (string) $newImg->encode());
} catch (ErrorException $e) {}
}
}
The error happened at line with Image::make(), even it's in the try catch block. I've checked all uploaded files and there are 2 cases of error here.

Some entry level Android phones upload 0 bytes image.

iPhones (iOS13/Safari) upload images that I can download them from server, and view on my Windows machine. But Laravel somehow couldn't process them, and return said error.
For those images uploaded from iPhone, I can't share them since it's the facial of the uploaders. Can't break privacy law. Instead, I could share exifs. Both are .JPEG.
Upload from iPhone #1:
