Laravel与图像干预:implode()无法正常工作

im currently trying to edit exif and iptc data with Image Intervention and Laravel. Up to this point it's working ok I guess, but when I try to use the exif-method, It returns an array instead of a string. OK I thought and tried to parse it into a string. I tried serialize(), but It returned a super ugly version of the array.

I stumbled upon the implode() function, which is what I need I think, but it somehow always returns the Array to String conversion Error even though I (think I) used it correctly..

Here's the code I used to parse it so far:

$exif = Image::make($path)->exif();
$exif = serialize($exif); //Super ugly version of the given array

And this:

$exif = Image::make($path)->exif();
$exif = implode(', ', $exif); //Returns "Array to string conversion" Error

Anyone got any Idea of how to fix this?

Thank you :)
