Filesize inconsistant

[David]

Not sure whether this is something Im doing wrong or just something
the filesize() function doesnt support but...

<?
$fsize1 = filesize("foo.t xt");
$fp = fopen("foo.txt" ,a);
$time = time();
fputs($fp,$time );
fclose($fp);
$fsize2 = filesize("foo.t xt");
echo $fsize1." ".$fsize2;
?>

this code always reports the $fsize1 equal to $fsize2 when surely they
should be different?

This is a clear RTFM:

"Note: The results of this function are cached."

You mean "a", not a.

http://php.net/clearstatcache is your friend.

Yeh thanks. Just in case anyone cares you can achieve what I wanted
like this as well:

$fp = fopen($filename ,"r");
fseek($fp, 0, SEEK_END);
$filesize1 = ftell($fp);
fclose($fp);

$time = time();
$fp = fopen($filename ,"w");
fputs($fp, $time);
fclose($fp);

$fp = fopen($filename ,"r");
fseek($fp, 0, SEEK_END);
$filesize2 = ftell($fp);
fclose($fp);

But that will always return the same filesize ("w" truncates file)
(unless you happend to to sumble upon a switch from x to x+ digits (last
time that happend was in 2001 IIRC, and will not happen for some time
:))

It will work, but only the first time you run it. If you replace $time
with data of varying length (as is the case for me) it will always
give different sizes.
