PHP IP 位址格式偵測函數

複製程式碼程式碼如下：

function checkIp($ip){
"", $ip);
    $ip = strtolower($ip);
    $ip= str_replace("http://", "", $ip);
    $ip= str_replace(" https://", "", $ip);
    if(preg_match('/[A-Za-z_-]/',$ip)){
        if(preg_match('/^([ w-] .)

複製程式碼

程式碼如下：

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-] .)

回傳 false;
}
}
else{
ipArray = ip.split(".");
j = ipArray.length
if(j!=4)
{
alert("不是正確的IP");
document.ipform.ip.focus();
回傳false;
}

for(var i=0;i{
if(ipArray[i].length==0 || ipArray[i]>255)
{

}
}
}
}

注意：上面的函數單行很長，大家複製後注意不要分行了。
