Question

所以我有以下两个IP范围

import
{
    AfterContentChecked,
    Directive,
    HostBinding,
    HostListener,
    Input,
    OnInit
} from '@angular/core';

@Directive({
    selector: '[imgspinloader]'
})
export class ImageSpinloaderDirective
{
    private defaultSrc: string = "assets/img/user-image-invitation-2x.png";

    @Input() @HostBinding() src;

    @Input() @HostBinding("class.img-loading") isLoading: boolean;

    @HostListener('load') complete()
    {
        this.isLoading = false;
    }

    @HostListener('error') onError()
    {
        this.src = this.defaultSrc;
        this.isLoading = false;
    }
}

我可以用什么php函数来区分ipv4范围和ipv6范围

需要这样的东西

2a02:c78::/29
2.120.0.0/13

Answer 1

此解决方案的功劳归于用户@deceze

function ip_range_type($range_ip)
{
    if (strpos($range_ip, ':') !== false) {
        //if ip range provided is ipv6 then
        echo "range provided is ipv6";
    } else {
        //if ip range provided is ipv4 then
        echo "range provided is ipv4";
    }
}
$range_ip = "2a02:c78::/29";
ip_range_type($range_ip);

IP地址具有很多范围，例如全部IPv4 Ranges，其网络地址和CIDR相同，您也可以检查IPv6 Ranges。 check IPv4 or IPv6 Range已在此处{{3}}高效地解释了您的问题。
