Rename function usage analysis _php techniques in PHP

This article analyzes the usage of rename () function in PHP. Share to everyone for your reference. Specifically as follows:

PHP filesystem function, rename () function renames a file or directory, and if successful, the function returns True. Returns False if the failure occurs.

Statement: rename (oldname,newname,context)

Parameters	Describe
Oldname	Required, specify the file or directory to be renamed.
NewName	Required, specify a new name for the file or directory
Context	Required, setting the context of a file handle, a set of options for modifying the behavior of a stream

Note: Before PHP 4.3.3, rename () cannot rename a file across a disk partition on a *nix based system.

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

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

Copy Code code as follows:

<?php
Rename ("Images", "pictures");
?>

OldPath----file or directory original path, $newpath----New definition path, then rename ($oldpath, $newpath) can complete file/directory move operation, after my test, This feature is supported by both Win32 and UNIX PHP4 versions.

In addition, as if the Win32 version of PHP4 cancels the unlink () function, you can also use the rename () function to complete the deletion, for example:

$path----file or directory path

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

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