Error loading XML into Laravel

Question

I am getting the error below when loading XML using Laravel. I tested the import with pure PHP and it was normally. Does anyone have any idea what it might be? I understand that " is quotes, but not found in XML.

simplexml_load_file(): I/O warning : failed to load external entity ""

Code line where the error occurs:

$xml = simplexml_load_file($request->file('publicacao')); dd($xml

Answer 1

As far as I’m concerned $request->file() (returns Illuminate\Http\UploadedFile) Laravel does not return a string, even if you look at the documentation you will notice that there is no __toString that should be the minimum for the first to return the temporary path of the file that is uploading, see the documentation:

• https://laravel.com/api/5.6/Illuminate/Http/UploadedFile.html

Then probably when passing the value to simplexml_load_file it is searching for a file that is not the correct file, probably what is between "", what was trying to pass was an object, so probably:

object(Illuminate\Http\UploadedFile)#1 (0) {
}

It is very likely that the mistakes of Warning are turned off or hidden, but if turned on would display something like:

PHP Warning: simplexml_load_file() expects Parameter 1 to be a Valid path, Object Given

The phrase object given means that it took an object, the previous sentence says, parameter 1 must be a valid path, that is, object is not path nor string.

How to read the contents of UploadedFile of the Laravel

Probably the right thing to do UploadedFile::get() + simplexml_load_string(), thus:

$xml = simplexml_load_string($request->file('publicacao')->get());
dd($xml);
