fileatime

(PHP3 , PHP4 )

fileatime -- Gets last access time of file

Description

int fileatime (string filename)

Returns the time the file was last accessed, or false in case of an error. The time is returned as a Unix timestamp.

The results of this function are cached. See clearstatcache() for more details.

Note: The atime of a file is supposed to change whenever the data blocks of a file are being read. This can be costly performancewise when an appliation regularly accesses a very large number of files or directories. Some Unix filesystems can be mounted with atime updates disabled to increase the performance of such applications; USENET news spools are a common example. On such filesystems this function will be useless.
