Description
Behavior

: Prior to PHP 4.3.3, rename() could not be renamed across disk partitions on *nix-based systems. Name the file.

Note: The encapsulation protocol used in oldname must match the one used in newname.

Note: Support for context was added in PHP 5.0.0.

The code is as follows:

oldpath ---- the original path of the file or directory, $newpath ---- the new defined path, then rename($oldpath,$newpath) can be completed The file/directory moving operation, after my testing, both win32 and unix php4 versions support this function.

In addition, it seems that the win32 version of php4 has canceled the unlink() function, so you can also use rename cleverly () function to complete the

delete

operation, for example:

$path ---- file or directory path

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

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