这是我计算来自ips的点击次数的函数,
function get_client_ip() {
$ipaddress = '';
if (getenv('HTTP_CLIENT_IP'))
$ipaddress = getenv('HTTP_CLIENT_IP');
else if(getenv('HTTP_X_FORWARDED_FOR'))
$ipaddress = getenv('HTTP_X_FORWARDED_FOR');
else if(getenv('HTTP_X_FORWARDED'))
$ipaddress = getenv('HTTP_X_FORWARDED');
else if(getenv('HTTP_FORWARDED_FOR'))
$ipaddress = getenv('HTTP_FORWARDED_FOR');
else if(getenv('HTTP_FORWARDED'))
$ipaddress = getenv('HTTP_FORWARDED');
else if(getenv('REMOTE_ADDR'))
$ipaddress = getenv('REMOTE_ADDR');
else
$ipaddress = 'UNKNOWN';
return $ipaddress;
}
和点击计数器
function update_visitas($id,$ip) {
global $dbc;
$sql = "SELECT COUNT(*) FROM ipclicks WHERE ip = " . ip2long($ip) . " and ads = " . $id;
$res=mysqli_query($dbc,$sql);
if (mysqli_result($res, 0)==0){
$sql = "INSERT INTO ipclicks VALUES (" . ip2long($ip) . "," . $id . ")";
#echo $sql;
$res=mysqli_query($dbc,$sql);
$sql = "UPDATE ads SET vistas = vistas +1 WHERE id_ad = " . $id;
#echo $sql;
$res=mysqli_query($dbc,$sql);
}
}
如何在此函数中替换mysqli_result以避免此错误? 致命错误:调用未定义的函数mysqli_result()
答案 0 :(得分:0)
不推荐使用的mysql函数和mysqli函数之间没有完全匹配的1:1。您必须将一行作为数组获取,然后检查它的一个元素。
示例:
$res = mysqli_query($dbc,$sql);
$row = mysqli_fetch_row($res);
if ($row[0]==0){
