session help

[iostream71]

i was using this script to test a no reloading hit counter:

<?php
session_start();
$filename = &quot;counter.dat&quot;;
$fp = fopen ($filename, &quot;r&quot;
$hits = fread ($fp, filesize($filename));
fclose ($fp);
//add hit if no session active
if (!isset($HTTP_SESSION_VARS['count'])) {
//was using: session_register('count'); but never
//would enter 'if'
$HTTP_SESSION_VARS['count'] = 1;
$hits++;
$fp = fopen( $filename,&quot;w&quot;
fwrite($fp, $hits, filesize($filename));
fclose( $fp );
}
//write to flash
print &quot;&counterValue=&quot;;
print $hits;
?>

problem is, it resets to 1 after 10 hits every time.
here is my phpinfo:

Something is wrong with the file operation.

function fread(),fwrite() read or write binary datas into
a file.But your $hits is a string,that's to say,10 means
character 1 and 0,2 bytes.Therefore when you want to write 10 to file,in fact you write 1 to file because filesize() returns 1 byte.

If you want to solve this problem,you can define the file size by yourself or replace the filesize() with strlen($hits).

enjoy yourself.

but i do the exact same thing with another script and it works(the reading writing part). i have a value that's passed into the script from flash and it writes it no problem. is that a different situation?
