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 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.

Could be a problem of concurrent uploads, because you use the same file name for all the files. If user uploads two images at the same time one gets corrupted, it can not be opened by the other request. I suggest you to do cropping before uploading it to Storage::disk('original_images').
Concurrent upload can happen easily just by double clicking a form submit button, so this is a common error.
