Rename () function in php

In php, the rename () function is the php filesystem function. the rename () function is used to rename the file or directory. if the file or directory is successfully renamed, the function returns true. If it fails, false is returned.

Statement: rename (oldname, newname, context)

Parameter description

Oldname is required and specifies the file or directory to be renamed.

Newname is required. it specifies the new name of the file or directory.

Context is required. it 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.

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.
