本文实例讲述了PHP实现获取ip地址的5种方法,以及插入用户登录日志操作。分享给大家供大家参考,具体如下:
php 获取ip地址的5种方法,插入用户登录日志实例,推荐使用第二种方法
<?php //方法1:
$ip = $_SERVER["REMOTE_ADDR"];
echo $ip;
//方法2:
$ip = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];
$ip = ($ip) ? $ip : $_SERVER["REMOTE_ADDR"];
echo $ip;
//方法3:
function getRealIp()
{
$ip=false;
if(!empty($_SERVER["HTTP_CLIENT_IP"])){
$ip = $_SERVER["HTTP_CLIENT_IP"];
}
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) {
$ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']);
if ($ip) { array_unshift($ips, $ip); $ip = FALSE; }
for ($i = 0; $i < count($ips); $i++) {
if (!eregi ("^(10│172.16│192.168).", $ips[$i])) {
$ip = $ips[$i];
break;
}
}
}
return ($ip ? $ip : $_SERVER['REMOTE_ADDR']);
}
echo getRealIp();
//方法4:
if ($HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"])
{
$ip = $HTTP_SERVER_VARS["HTTP_X_FORWARDED_FOR"];
}
elseif ($HTTP_SERVER_VARS["HTTP_CLIENT_IP"])
{
$ip = $HTTP_SERVER_VARS["HTTP_CLIENT_IP"];
}
elseif ($HTTP_SERVER_VARS["REMOTE_ADDR"])
{
$ip = $HTTP_SERVER_VARS["REMOTE_ADDR"];
}
elseif (getenv("HTTP_X_FORWARDED_FOR"))
{
$ip = getenv("HTTP_X_FORWARDED_FOR");
}
elseif (getenv("HTTP_CLIENT_IP"))
{
$ip = getenv("HTTP_CLIENT_IP");
}
elseif (getenv("REMOTE_ADDR"))
{
$ip = getenv("REMOTE_ADDR");
}
else
{
$ip = "Unknown";
}
echo $ip ;
//方法5:
if(getenv('HTTP_CLIENT_IP')) {
$onlineip = getenv('HTTP_CLIENT_IP');
} elseif(getenv('HTTP_X_FORWARDED_FOR')) {
$onlineip = getenv('HTTP_X_FORWARDED_FOR');
} elseif(getenv('REMOTE_ADDR')) {
$onlineip = getenv('REMOTE_ADDR');
} else {
$onlineip = $HTTP_SERVER_VARS['REMOTE_ADDR'];
}
echo $onlineip;
实例:在用户登录时获取用户IP,插入到数据库登录日志表里
//增加用户登录日志
$ip = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];
$ip = ($ip) ? $ip : $_SERVER["REMOTE_ADDR"];
$this->usermodel->addUserlog($userid,$nickname,$ip);
function addUserlog($userid,$nickname,$ip) {
try {
$now = date("Y-m-d H-i-s",time());
$data=array(
'userid'=>$userid,
'nickname'=>$nickname,
'ip'=>$ip,
'logintime'=>$now
);
$insert_query = $this->db->insert_string('user_log', $data);
$this->db->query($insert_query);
return 0;
} catch ( Exception $e ) {
return -1;
}
}
日志表结构:
CREATE TABLE `user_log` (
`id` bigint(20) NOT NULL AUTO_INCREMENT,
`userid` bigint(20) NOT NULL,
`nickname` varchar(50) NOT NULL,
`ip` varchar(50) NOT NULL,
`logintime` datetime NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8
