What do you mean by PHP inside Vue? I didn't understand that.
Please explain, based on that I will definitely try to solve your query

I saw your video- https://www.youtube.com/watch?v=9B-xriETQ9M, You are using php, vue and laravel in this project. Actually, i am also doing image upload in vuejs but in above code you are calling php in line no.47- window.axios.post('/file/upload', formData, headers) , in my scenario i am not using php with vuejs. In vuejs $file->storeAs('/uploads', $filename) - storeAs is not function in Vuejs, it is use in php.
I am doing image upload, when i upload the image that image can transfer to local drive (absolute)path to the project's folder path in vuejs. actually i want image path , that path i am giving backend and backend person are access that image path and copy to according use. I have tried multer and fs-extra npm packge for upload image move local drive to another folder(inside project folder) but these libaries not working.
