PHP code that converts IP addresses and numbers to each other

$ip = "182.18.8.196";
echo '';
echo ip2long($ip);
echo " @ ";
echo $ipfu = ip2int($ ip);
echo ' @ ';
$ip_n = bindec(decbin(ip2long($ip)));
echo $ip_n;
echo ' @ ';
echo long2ip($ip_n);
echo ' @ ';
echo long2ip($ipfu);//Convert numbers to IP
//You can directly use this function to get the number converted from the IP address.
function myip2long($ip){
return bindec(decbin(ip2long($ip)));
}
//This function is equivalent to ip2long
function ip2int($ip){
 list($ip1,$ip2,$ip3,$ip4)=explode(".",$ip);
return ($ip1<<24)|($ip2<<16)|($ip3<< ;8)|($ip4);
}

This way you can get the correct result: -1240332092 @ -1240332092 @ 3054635204 @ 182.18.8.196 @ 182.18.8.196 3054635204

Directly call the myip2long function to get a positive number. Articles you may be interested in: php code to realize IP address and number exchange
