imagedestroy — Destroy an image
Nota:
This function has no effect. Prior to PHP 8.0.0, this function was used to close the resource.
Prior to PHP 8.0.0, imagedestroy() freed any memory
associated with the image
resource. As of 8.0.0,
the GD extension uses objects instead of resources, and objects
cannot be explicitly closed.
