PHP IP地址格式检测函数

        $ipArray = explode(".", $ip);
        $j = count($ipArray);
        if($j!=4)
        {
            return false;
        }
        for( $i=0;$i

            if(strlen($ipArray[$i])==0 || $ipArray[$i]>255){
                return false;
            }
        }
        return true;
    }

}

JS代码：

复制代码代码如下:

function checkIP(){
var ipArray,ip,j;
ip = document.ipform.ip.value;

if (ip.indexOf(" ")>=0){
ip = ip.replace(/ /g,"");
document.ipform.ip.value = ip;
}
if (ip.toLowerCase().indexOf("http://")==0){
ip = ip.slice(7);
document.ipform.ip.value = ip;
}
if (ip.toLowerCase().indexOf("https://")==0){
ip = ip.slice(8);
document.ipform.ip.value = ip;
}
if (ip.slice(ip.length-1)=="/"){
ip = ip.slice(0,ip.length-1);
document.ipform.ip.value = ip;
}

if(/[A-Za-z_-]/.test(ip)){
if(!/^([\w-]+\.)+((com)|(net)|(org)|(gov\.cn)|(info)|(cc)|(com\.cn)|(net\.cn)|(org\.cn)|(name)|(biz)|(tv)|(cn)|(mobi)|(name)|(sh)|(ac)|(io)|(tw)|(com\.tw)|(hk)|(com\.hk)|(ws)|(travel)|(us)|(tm)|(la)|(me\.uk)|(org\.uk)|(ltd\.uk)|(plc\.uk)|(in)|(eu)|(it)|(jp)|(co)|(me)|(mx)|(ca)|(ag)|(com\.co)|(net\.co)|(nom\.co)|(com\.ag)|(net\.ag)|(fr)|(org\.ag)|(am)|(asia)|(at)|(be)|(bz)|(com\.bz)|(net\.bz)|(net\.br)|(com\.br)|(de)|(es)|(com\.es)|(nom\.es)|(org\.es)|(fm)|(gs)|(co\.in)|(firm\.in)|(gen\.in)|(ind\.in)|(net\.in)|(org\.in)|(jobs)|(ms)|(com\.mx)|(nl)|(nu)|(co\.nz)|(net\.nz)|(org\.nz)|(tc)|(tk)|(org\.tw)|(idv\.tw)|(co\.uk)|(vg)|(ad)|(ae)|(af)|(ai)|(al)|(an)|(ao)|(aq)|(ar)|(as)|(au)|(aw)|(az)|(ba)|(bb)|(bd)|(bf)|(bg)|(bh)|(bi)|(bj)|(bm)|(bn)|(bo)|(br)|(bs)|(bt)|(bv)|(bw)|(by)|(cd)|(cf)|(cg)|(ch)|(ci)|(ck)|(cl)|(cm)|(cr)|(cu)|(cv)|(cx)|(cy)|(cz)|(dj)|(dk)|(dm)|(do)|(dz)|(ec)|(ee)|(eg)|(er)|(et)|(fi)|(fj)|(fk)|(fo)|(ga)|(gd)|(ge)|(gf)|(gg)|(gh)|(gi)|(gl)|(gm)|(gn)|(gp)|(gq)|(gr)|(gt)|(gu)|(gw)|(gy)|(hm)|(hn)|(hr)|(ht)|(hu)|(id)|(ie)|(il)|(im)|(iq)|(ir)|(is)|(je)|(jm)|(jo)|(ke)|(kg)|(kh)|(ki)|(km)|(kn)|(kr)|(kw)|(ky)|(kz)|(lb)|(lc)|(li)|(lk)|(lr)|(ls)|(lt)|(lu)|(lv)|(ly)|(ma)|(mc)|(md)|(mg)|(mh)|(mk)|(ml)|(mm)|(mn)|(mo)|(mp)|(mq)|(mr)|(mt)|(mu)|(mv)|(mw)|(my)|(mz)|(na)|(nc)|(ne)|(nf)|(ng)|(ni)|(no)|(np)|(nr)|(nz)|(om)|(pa)|(pe)|(pf)|(pg)|(ph)|(pk)|(pl)|(pm)|(pn)|(pr)|(ps)|(pt)|(pw)|(py)|(qa)|(re)|(ro)|(ru)|(rw)|(sa)|(sb)|(sc)|(sd)|(se)|(sg)|(si)|(sk)|(sl)|(sm)|(sn)|(sr)|(st)|(sv)|(sy)|(sz)|(td)|(tf)|(tg)|(th)|(tj)|(tl)|(tn)|(to)|(tr)|(tt)|(tz)|(ua)|(ug)|(uk)|(uy)|(uz)|(va)|(vc)|(ve)|(vi)|(vn)|(vu)|(wf)|(ye)|(yt)|(yu)|(za)|(zm)|(zw))$/i.test(ip)){
alert("不是正确的域名");
document.ipform.ip.focus();
return false;
}
}
else{
ipArray = ip.split(".");
j = ipArray.length
if(j!=4)
{
alert("不是正确的IP");
document.ipform.ip.focus();
return false;
}

for(var i=0;i{
if(ipArray[i].length==0 || ipArray[i]>255)
{
alert("不是正确的IP");
document.ipform.ip.focus();
return false;
}
}
}
}

注意：上面的函数单行很长，大家复制后注意不要分行了。
