Rename function usage analysis in PHP, Phprename function usage

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

The PHP filesystem function, the rename () function renames the file or directory, and if successful, the function returns True. If it fails, it returns false.

Statement: rename (oldname,newname,context)

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

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.
Copy the Code code as follows: <?php
Rename ("Images", "pictures");
?>

OldPath----The original path of the file or directory, $newpath----The new defined path, then rename ($oldpath, $newpath) can complete the file/directory move operation, after my test, This feature is supported in the PHP4 versions of Win32 and UNIX.

In addition, 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).

I hope this article is helpful to everyone's PHP programming.
