php Get the IP address of the server_PHP tutorial

A simple IP address acquisition code, but this can only obtain the IP on the server and cannot be used on the client. Friends in need can refer to it.

The code is as follows

代码如下	复制代码
/**  * 获取服务器的ip  * @access      public  * @return string  **/ function real_server_ip(){  static $serverip = NULL;    if ($serverip !== NULL){   return $serverip;  }    if (isset($_SERVER)){   if (isset($_SERVER['SERVER_ADDR'])){    $serverip = $_SERVER['SERVER_ADDR'];   }   else{    $serverip = '0.0.0.0';   }  }  else{   $serverip = getenv('SERVER_ADDR');  }    return $serverip; }

Copy code

/**
* Get the server’s ip
* @access public
* @return string
**/
function real_server_ip(){
static $serverip = NULL;

if ($serverip !== NULL){
return $serverip;
}

if (isset($_SERVER)){
if (isset($_SERVER['SERVER_ADDR'])){
$serverip = $_SERVER['SERVER_ADDR'];
}
else{
$serverip = '0.0.0.0';
}
}
else{
$serverip = getenv('SERVER_ADDR');
}

return $serverip;
}
