Notes
Note:
Note: In most Unix filesystems, a file is considered changed when its
inode data is changed; that is, when the permissions, owner, group, or
other metadata from the inode is updated. See also
filemtime (which is what you want to use when you
want to create "Last Modified" footers on web pages) and
fileatime.
Note:
Note also that in some Unix texts the ctime of a file is referred to as
being the creation time of the file. This is wrong. There is no creation
time for Unix files in most Unix filesystems.
Note:
Note that time resolution may differ
from one file system to another.
Note: The results of this

TipAs of PHP 5.0.0, this function
can also be used with some URL wrappers. Refer to
Supported Protocols and Wrappers to determine which wrappers support
stat family of functionality.
