PHP Tutorial Rename () function

PHP filesystem functions

Definition and usage

The rename () function renames the file or directory.

If successful, the function returns True. If it fails, it returns false.

Grammar

Rename (Oldname,newname,context)

Parameters	Description
Oldname	Necessary. Specifies the file or directory to be renamed.
NewName	Necessary. Specify a new name for the file or directory.
Context	Necessary. Specifies the environment for file handles. Context is a set of options for modifying the behavior of a stream.

Hints and Notes

Note: rename () cannot rename files across disk partitions in a *nix-based system until PHP 4.3.3.

Note: The encapsulation protocols used in Oldname must match those used in newname.

Note: support for the context is added by PHP 5.0.0.

Example

OldPath----file or directory original path

$newpath----a new defined path

Then rename ($oldpath, $newpath) will be able to complete the operation of File/directory move

Through my tests, Win32 and UNIX versions of PHP4 support this feature.

Also, as if PhP4 's Win32 version cancels the unlink () function. You can also use the rename () function to complete the removal operation, for example:

$path----file or directory path

$TMP----tmp directory (/tmp)

Move the file to the TMP directory with rename ($path, $tmp).
