PHP获取IP的方法有许多种,我们今天向大家总结了六种方法,希望通过对这六种方法的学习,能够加深我们对PHP语言的进一步了解,巩固我们所掌握的知识。

PHP获取IP方法一:

<?phpecho"<br>";?><?phpfunctionGetIP(){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!";return$cip;}echo"<br>";?>

PHP获取IP方法二:

<?phpecho"<br>";?><?error_reporting(E_ERROR|E_WARNING|E_PARSE);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{$ip="Unknown";}echo"你的IP地址是:".$ip."<br>";?>

PHP获取IP方法三:

<?phpecho"<br>";?><?$iipp=$_SERVER["REMOTE_ADDR"];echo$iipp;echo"<br>";?>

PHP获取IP方法四:

<?phpecho"<br>";?><?php$user_IP=($_SERVER["HTTP_VIA"])?$_SERVER["HTTP_X_FORWARDED_FOR"]:$_SERVER["REMOTE_ADDR"];$user_IP=($user_IP)?$user_IP:$_SERVER["REMOTE_ADDR"];echo$user_IP."<br>";?>

PHP获取IP方法五:

<?phpecho"<br>";?><?functionget_real_ip(){$ip=false;if(!empty($_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']);}echoget_real_ip();echo"<br>";?>

PHP获取IP方法六:

<?phpecho"<br>";?><?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;echo"<br>";?>
