限制同IP註冊人數代碼_PHP教程

今天我們來看看限制同IP註冊人數代碼的代碼吧,注要用到datediff 函數哦,很簡單的.

$ex_sql =mysql_query("Select * from wk_member where m_ip='$ip' and datediff(m_dtime,'$dtime')=0");
if(mysql_num_rows($ex_sql)<5){
$sql;
if(mysql_query($sql)){
$_SESSION['uid']=array(mysql_insert_id(),$uid,$mo);
exit("");
}else{
alert('註冊失敗!','');
}
}else{
alert('對不起,同IP一天只能註冊5個使用者','');
}

這樣就可以做投票限制IP的程式了,哈哈最後本站原創轉載請註明www.111cn.cn/phper/php.html
