PHP obtains IP address and outputs it as array program code_PHP tutorial

There are many ways to obtain the IP address in PHP. Below I will introduce the use of Linux commands to obtain the IP address and then convert it into an array for output. The following also introduces some common examples of PHP IP address processing.

PHP Get Server IP Address

Use PHP to execute ifconfig to obtain the Linux server IP and output it as an array. The following is the code:

The code is as follows

Copy code

代码如下	复制代码
function getServerIp(){ //用ifconfig读取服务器IP并输出为数组 $ss = exec('/sbin/ifconfig | sed -n 's/^ *.*addr:([0-9.]{7,}) .*$/1/p'',$arr); return $arr; } $ips=getServerIp(); foreach($ips as $k=>$v){//过滤IP  if(substr($v,0,3)=='127' || substr($v,0,3)=='10.' || substr($v,0,7)=='192.168' || substr($v,0,6)=='172.16'){   unset($ips[$k]);  } } shuffle($ips);//重新排序 print_r($ips); ?>

function getServerIp(){ //Use ifconfig to read the server IP and output it as an array
$ss = exec('/sbin/ifconfig | sed -n 's/^ *.*addr:([0-9.]{7,}) .*$/1/p'',$arr);< br /> return $arr;
}
$ips=getServerIp();

foreach($ips as $k=>$v){//Filter IP
if(substr($v,0,3)=='127' || substr($v,0,3)=='10.' || substr($v,0,7)=='192.168' | | substr($v,0,6)=='172.16'){
unset($ips[$k]);
}
}
shuffle($ips);//Reorder
print_r($ips);
?>

Some examples of obtaining IP address with php

代码如下	复制代码
function GetIP(){ 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 GetIP(); ?>

The code is as follows	Copy code
function GetIP(){ 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 = "Unable to obtain!"; } return $cip; } echo GetIP(); ?>

I have a relatively common method to obtain the user’s IP address:

代码如下

复制代码

function get_user_ip() {         if (isset($_SERVER['HTTP_CLIENT_IP']) && $_SERVER['HTTP_CLIENT_IP']!='unknown') {             $ip = $_SERVER['HTTP_CLIENT_IP'];         } elseif (isset($_SERVER['HTTP_X_FORWARDED_FOR']) && $_SERVER['HTTP_X_FORWARDED_FOR']!='unknown') {             $ip = $_SERVER['HTTP_X_FORWARDED_FOR'];         } else {             $ip = $_SERVER['REMOTE_ADDR'];         }         return $ip;     }

PHP gets the IP location (call Sina API to get the IP location)

代码如下

复制代码

function get_location($ip){  $curl = curl_init();         curl_setopt($curl,CURLOPT_URL, "http://int.dpool.sina.com.cn/iplookup/iplookup.php?format=json&ip=".$ip);  $location = curl_exec($curl);         $location = json_decode($location);         if($location===FALSE) return "";         return empty($location->desc) ? $location->province.$location->city.$location->district.$location->isp : $location->desc; }
