[請益] 計數器該如何隔夜歸零呢?

[ntuguy (ya)]

最近寫了個計數器
似乎work起來都ok
但我希望他能隔夜歸零
懇談大大們指點一下該如何做呢?
謝謝!!

<?php

        if (file_exists('count_day.txt'))
        {
                $fil = fopen('count_day.txt', r);
                $dat = fread($fil, filesize('count_day.txt'));
 $totalnow = $dat+1;
 echo "document.write(\"$totalnow\");";

fclose($fil);
                $fil = fopen('count_day.txt', w);
                fwrite($fil, $dat+1);
        }

        else
        {
                $fil = fopen('count_day.txt', w);
                fwrite($fil, 1);
                echo '1';
                fclose($fil);
        }
?>
