Tips and comments

Note: Before PHP 4.3.3, rename () cannot rename files across disk partitions in * nix-based systems.

Note: The Encapsulation Protocol used in oldname must match that used in newname.

Note: The support for context is added in PHP 5.0.0.

The PHP instance code is as follows:

2. Rename ("images", "pictures ");
3. ?>
4.  
6. $ File = "html/cache.txt ";
7. $ Rename = "html/rename.txt ";
8. If (rename ($ file, $ rename )){

15. Rename ("file", "html/files ");
