if(isset($Submit)) //如果有新内容提交
{
if(!file_exists("voterec.txt"))
{
//各种选票数目都是0
$voterec = array(0, 0, 0, 0, 0);
}
else
{
//读出投票记录
$voterec = file("voterec.txt");
}
//更新投票记录
$voterec[$vote - 1] += 1;
//写入新的投票记录
$fp = fopen("voterec.txt", "w+");
$total = 0;
for($i = 0; $i {
$voterec[$i] = chop($voterec[$i]);
$total += $voterec[$i];
fwrite($fp, $voterec[$i]." ");
}
fclose($fp);
}
?>
