Definition and Usage

The fileatime() function returns the last access time of the specified file.

Note: The result of this function is cached. Use clearstatcache() to clear the cache.

Note: The atime of a file changes each time the data of a file are being read. This can decrease the performance if an application accesses a large number of files or directories. Some Unix systems have access time updates disabled to increase performance. In this case this function is useless.
