What is the easiest way to duplicate an image variable in PHP.
Normally you can simply do $varnew = $varold.
But with a GD library variable if I did the above and then edited $varnew then $varold would be effected too.
Obviously one way would be to reopen the file or to make a new image and copy it into it. Is there an easier way?
The reason your try didn’t work is because the variable only stores a handle (a memory pointer) to the GD image. Both
$varnewand$varoldwill still store the same pointer, thus pointing to the exact same image in memory. You have to use imagecopy or, maybe worse, open the image from file again.
