我一直试图想出一种方法来将IP地址存储为PHP的无符号整数,但我想我对如何提出正确的函数并不熟悉。这是我想出的(错误的):
// ip 2 unsigned int
function ip2int($ipaddress) {
// turns IP into signed integer
$signed = ip2long($ipaddress);
$unsigned = sprintf("%u", $signed);
return $unsigned;
}
// unsigned int 2 ip
function int2ip($unsigned) {
$signed = sprintf("%d", $unsigned);
$ipaddress = long2ip($signed);
return $ipaddress;
}
有关如何解决此问题的任何建议吗?

long2ip将整数转换为IP格式,而ip2long则反之亦然 像这样使用
$long = ip2long($_SERVER['REMOTE_ADDR']);//or your ip
$ip = long2ip($long);
