thanks for that .......it was really this simple mistake of access.....that was causing the problem......
well this peice of code works fine but......only once..... after that the same time is displayed......
i got trying something with clearstatcache(); but didn't knew the proper use and so not worked....
plz let me know .....if the image is cached ...how can this be removed from cache by PHP script ......so that any call to it be noted again...
<?php
$atime=fileatime("../images/sof.jpg");
echo "Time is $atime ";
echo"<BR><B>BALKAR HAS Accesed on ! :-) </B><BR> ";
echo $atime ;
exit("BALKAR");
?>
Thanks again
