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

是的，它们将覆盖指定路径上的现有文件（如果已存在）。

Answer 2

是的，我自己测试，如果你使用这些功能的第二个参数，它将替换现有的文件！
