Do imagejpeg(), imagepng() and imagegif() replace existent files?

Question

The title explains it quite well, do imagejpeg(), imagepng() and imagegif() replace an existent file if I use the 2nd parameter of these functions?

The second parameter is the location where you want to store the created image, but what if there is already a file with the name I chose? How do these functions handle those situations?

Thanks.

Answer 1

Yes, they will overwrite an existing file at the specified path, if it already exists.

Answer 2

Yes, I test it by myself, it will replace the existent file if you use the 2nd parameter of these functions ！
