       Example #1

	      fileatime(3) example

	      <?php

	      // outputs e.g.  somefile.txt was last accessed: December 29 2002 22:16:23.

	      $filename = 'somefile.txt';
	      if (file_exists($filename)) {

	      ?>

ERRORS
/EXCEPTIONS
	Upon failure, an E_WARNING is emitted.

NOTES
       Note

	       The  atime  of  a file is supposed to change whenever the data blocks of a file are being read. This can be costly performance-wise
	      when an application 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.

       Note

	      Note that time resolution may differ from one file system to another.

       Note

	      The results of this function are cached. See clearstatcache(3) for more details.

       Tip

	      As  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(3) family of functionality.
