php记录访问者ip
❶ 利用php怎么获取用户ip
php获取用户真实ip的方法:
方法1:
//获取REMOTE_ADDR属性,直接可以得到ip
$ip = $_SERVER["REMOTE_ADDR"];
echo $ip;
方法2:
//从Server中获取HTTP_VIA,如果获取到就用HTTP_X_FORWARDED_FOR的值替换,如果获取不到就取REMOTE_ADDR的值。
$user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] :
$_SERVER["REMOTE_ADDR"];
$user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];
echo $user_IP;
方法3:
function getRealIp()
{
$ip=false; //初始化ip为false
if(!empty($_SERVER["HTTP_CLIENT_IP"])){ //如果HTTP_CLIENT_IP不为空
$ip = $_SERVER["HTTP_CLIENT_IP"]; //获取HTTP_CLIENT_IP的值
}
if (!empty($_SERVER['HTTP_X_FORWARDED_FOR'])) { //如果HTTP_X_FORWARDED_FOR不为空
$ips = explode (", ", $_SERVER['HTTP_X_FORWARDED_FOR']);
//把HTTP_X_FORWARDED_FOR的值用,分割后存放数组ips
if ($ip) { array_unshift($ips, $ip); $ip = FALSE; }//遍历处理
for ($i = 0; $i < count($ips); $i++) {
if (!eregi ("^(10│172.16│192.168).", $ips[$i])) {
$ip = $ips[$i]; //获得真实ip
break;
}
}
}
return ($ip ? $ip : $_SERVER['REMOTE_ADDR']);
}
echo getRealIp();
❷ PHP记录访客IP生成HTML
<?php
function writeLog()
{
$fp = fopen("log.txt", "a+");
$data = array(date("Y-m-d H:i:s"),$_SERVER[REMOTE_ADDR],$_SERVER[HTTP_X_REWRITE_URL],
$_SERVER[HTTP_USER_AGENT],$_SERVER["HTTP_REFERER"]);
fputcsv($fp,$data,"\t");
fclose($fp);
}
function showHtml()
{
$fp = file("log.txt");
$table = '<table border="1">';
$count = count($fp);
if ($count<1) return;
for ($i=0;$i<100;$i++)
{
$count--;
if($count<1) break;
$line = $fp[$count];
$tr = str_replace("\t",'</td><td>',$line);
$tr = '<tr><td>'.$tr.'</tr>';
$table .= $tr;
}
$table .= '</table>';
echo $table;
}
writelog();
showHtml();
?>
❸ php中怎么获取访问当前页面电脑的IP地址
function getIP() {
$url=file_get_contents("";);
$ip=substr($url,85);
$ip=substr($ip,0,-4);
return $ip;
}
一个大神抛出的,不过需要访问一个链接(总是感觉慌慌的),建议用tp自带函数访问不到的再用这个方法
❹ php怎么记录访问者ip并生成日志
php获取访问者IP地址汇总
在很我的时候我们需要得到用户的真实IP地址,例如,日志记录,地理定位,将用户信息,网站数据分析等,其实获取IP地址很简单$_SERVER[\'REMOTE_ADDR\']就可以了。下面我们就来给大家汇总一下常用的几种获取IP地址的方法。
//方法1:
$ip = $_SERVER["REMOTE_ADDR"];
echo $ip;
//方法2:
代码如下:
$user_IP = ($_SERVER["HTTP_VIA"]) ? $_SERVER["HTTP_X_FORWARDED_FOR"] : $_SERVER["REMOTE_ADDR"];
$user_IP = ($user_IP) ? $user_IP : $_SERVER["REMOTE_ADDR"];
echo $user_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 $onlineip;
//方法6:
print "您的IP地址是:";
if(!empty($_SERVER["HTTP_CLIENT_IP"])){
$cip = $_SERVER["HTTP_CLIENT_IP"];
}
elseif(!empty($_SERVER["HTTP_X_FORWARDED_FOR"])){
$cip = $_SERVER["HTTP_X_FORWARDED_FOR"];
}
elseif(!empty($_SERVER["REMOTE_ADDR"])){
$cip = $_SERVER["REMOTE_ADDR"];
}
else{
$cip = "无法获取!";
}
print $cip;
保存TEXT中
<?php
$ip = $_SERVER['REMOTE_ADDR'];
$time = gmdate("H:i:s",time()+8*3600);
$file = "123.txt" ;
$fp=fopen ("123.txt","a") ;
$txt= "$ip"."----"."$time"."\n";
fputs($fp,$txt);
?>
