The script you've got doesn't change anything, just reports back the files found.
What changes are made to the files?
What changes are made to the files?
This is the case:
1. I use above script for read directory content of images files. For example, result are 10 image files content.
2. I use another script for add new image files to the same directory read from 1. For example, add 20 new image files to directory.
3. I execute again de first script for reread directory content, but result only show first 10 image files hoe directory content, not 30 image files how there are.
Php version is 5.x
