如何使用PHP获取IP表单浏览器地址栏

我认为这就是你想要的：

echo $_SERVER['REMOTE_ADDR'];

你也应该看看这里

获取 IP 的另一种方法是使用 explode

$url='https://192.168.40.32/example.com/';
$first=explode('//',$url);
$string=explode('/',$first[1]);
var_dump($string[0]); //192.168.40.32

try this 
<?php 
$ipAddress = $_SERVER['REMOTE_ADDR'];
if (array_key_exists('HTTP_X_FORWARDED_FOR', $_SERVER)) {
    $ipAddress = array_pop(explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']));
}
?>

这是一个尝试在 url 栏中查找 ip 地址的函数，如果它在那里没有任何 ip，它将在 $_SERVER 数组中查找 IP 地址。

<?php
function uriIP() {
    $s = $_SERVER['HTTP_HOST'];
    //Look for a number with dots made like: ***.*.**.*** ex.
    preg_match('/[0-9]{1,3}[.][0-9]{1,3}[.][0-9]{1,3}[.][0-9]{1,3}/i', $s, $matches);
    if (!isset($matches[0])) {
        //Check to see if we have an IP address stored in the $_SERVER array
        if ($_SERVER['SERVER_ADDR']) {
            //Return the value if we find any (true)
            return $_SERVER['SERVER_ADDR'];
        } else {
            //nothing found here, return false
            return false;
        }
    //if we found a match in our regex, return the first match:
    } else {
        return $matches[0];
    }
}
print_r(uriIP());

如果 IP 地址在字符串中重复，最好使用正则表达式。preg_match

<?php
//Example - 1
$server_name='https://192.168.40.32/example.com/192.168.40.33/192.168.40.34'; //$_SERVER['SERVER_NAME'];
$pattern = '/'d{1,3}'.'d{1,3}'.'d{1,3}'.'d{1,3}/'; //regex pattern
preg_match($pattern, $server_name, $ip_data); //get the correct ip address
$ip = $ip_data[0]; //its an array 
print_r($ip); // display to see result.
?>

您可以使用获取IP地址;

$_SERVER['REMOTE_ADDR']

<?php
//Example - 2
$url = $_SERVER['REMOTE_ADDR']; //get the ip address
$my_valid_ip = filter_var($url, FILTER_VALIDATE_IP); // check the ip address if its valid
print_r($my_valid_ip); //display to see result.
?>
