❶ php 怎么通过ip来获取所在位置
可以使用第三方接口 比如网络地图 它可以通过ip来定位用户的经纬度坐标 有了坐标就可以直接定位用户所在城市和具体位置
❷ php到底怎么获取IP地址，为什么三种方法获取的IP都不一样
php获取真实IP地址，参考方法如下：
functionGetIP(){
if(getenv("HTTP_CLIENT_IP")&&strcasecmp(getenv("HTTP_CLIENT_IP"),"unknown"))
$ip=getenv("HTTP_CLIENT_IP");
elseif(getenv("HTTP_X_FORWARDED_FOR")&&strcasecmp(getenv("HTTP_X_FORWARDED_FOR"),"unknown"))
$ip=getenv("HTTP_X_FORWARDED_FOR");
elseif(getenv("REMOTE_ADDR")&&strcasecmp(getenv("REMOTE_ADDR"),"unknown"))
$ip=getenv("REMOTE_ADDR");
elseif(isset($_SERVER['REMOTE_ADDR'])&&$_SERVER['REMOTE_ADDR']&&strcasecmp($_SERVER['REMOTE_ADDR'],"unknown"))
$ip=$_SERVER['REMOTE_ADDR'];
else
$ip="unknown";
return($ip);
}
❸ 如何使用php获取本机IP地址
function ip() {
if(getenv('HTTP_CLIENT_IP') && strcasecmp(getenv('HTTP_CLIENT_IP'), 'unknown')) {
$ip = getenv('HTTP_CLIENT_IP');
} elseif(getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) {
$ip = getenv('HTTP_X_FORWARDED_FOR');
} elseif(getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) {
$ip = getenv('REMOTE_ADDR');
} elseif(isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
$ip = $_SERVER['REMOTE_ADDR'];
}
return preg_match ( '/[\d\.]{7,15}/', $ip, $matches ) ? $matches [0] : '';
}
以上函数取自phpcms的获取ip方法
❹ php 获取客户端的电脑名称
PHP在局域网中获取客户端计算机名、IP地址
<?
//php获取ip的算法
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'];
}
exec ("ping $onlineip");
$macaddress=exec ("arp -a | find /i".' "'.$onlineip.'"');
$computername=exec ('nbtstat -A'.' '.$onlineip.' | find /i "20"');
$MacName=(preg_split("/\s+/", trim($macaddress)));
$UserName=(preg_split("/\s+/", trim($computername)));
echo "计算机名：".$UserName[0]." --- "."IP 地址：".$MacName[0]." --- "."MAC 地址：".$MacName[1];
?>
class GetMacAddr
{
var $return_array = array(); // 返回带有MAC地址的字串数组
var $mac_addr=array();
function GetMacAddr()
{
switch (strtolower(PHP_OS) )
{
case "linux":$this->forLinux();break;
case "solaris":break;
case "unix":break;
case "aix":break;
default:$this->forWindows();break;
}
//www.51qgj.com
$temp_array = array();
foreach ( $this->return_array as $value )
{
if ( preg_match( "/[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f]/i", $value, $temp_array ) )
{
$this->mac_addr[] = $temp_array[0];
}
}
unset($temp_array);
return $this->mac_addr;
}
function forWindows()
{
@exec("ipconfig /all", $this->return_array);
if ( $this->return_array )
return $this->return_array;
else{
$ipconfig = $_SERVER["WINDIR"]."\system32\ipconfig.exe";
if ( is_file($ipconfig) )
@exec($ipconfig." /all", $this->return_array);
else
@exec($_SERVER["WINDIR"]."\system\ipconfig.exe /all", $this->return_array);
return $this->return_array;
}
}
function forLinux()
{
@exec("ifconfig -a", $this->return_array);
return $this->return_array;
}
}
$mac = new GetMacAddr();
echo "<pre>";
print_r( $mac->mac_addr);
?>
mac测试过 可能无效
