This article analyzes the rename () function usage in php. Share it with you for your reference. The details are as follows:

Php filesystem function. rename () function renames a file or directory. if the file is successfully renamed, the function returns true. If it fails, false is returned.

Statement: rename (oldname, newname, context)

Parameters	Description
Oldname	Required. specifies the file or directory to be renamed.
Newname	Required. specifies the new name of the file or directory.
Context	Required. specifies the file handle environment. context is a set of options for modifying stream behavior.

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 code is as follows:

<? Php
Rename ("images", "pictures ");
?>

Oldpath ---- file or directory original path, $ newpath ---- New defined path, then rename ($ oldpath, $ newpath) can complete the file/directory movement operation, after my test, both win32 and unix php4 support this function.

In addition, if the unlink () function is canceled in the win32 version of php4, you can also use the rename () function to delete the function. for example:

$ Path ---- file or directory path

$ Tmp ---- tmp Directory (/tmp)

Use rename ($ path, $ tmp) to move the file to the tmp directory.
