PHP计数器的问题

Code：

<?php
$RHand = fopen("COUNT.TXT","rb") ;
$COUNT = fread($RHand,filesize("COUNT.TXT"));   //读取文件
fclose($RHand);
If($_COOKIE['COUNTER-COOKIES']="1")   //若该计数器的Cookies的值为1
{
echo "<hr><br><p align='center'>已访问该页的访问者有".$COUNT."位</p>";   
}
else
{
setcookie('COUNTER-COOKIES','1',mktime(12,0,0,1,1,2050));  //写入判断是否访问该页的Cookies
$Hand = fopen("COUNT.TXT","w+");  
$COUNT3 = $COUNT+1;
fwrite($Hand,$COUNT3);    //写入文件
fclose($Hand);
echo "<hr><br><p align='center'>已访问该页的访问者有".$COUNT."位</p>";  
}
?>
无论如何访问该网页，都是只会显示有0位访问者，清掉浏览器Cookies也如此。Count.txt文件已获得Owner、Group、Everyone三用户的写入权限。
