The content of this article is about PHP checking whether the IP is legal. It has certain reference value. Now I share it with everyone. Friends in need can refer to it

No regular judgment is used, just a function written in PHP to verify whether the IP address is legal
function checkIp($ip){
$arr=explode('.',$ip);
if(count($arr) != 4){
return false;
}else{
for($i = 0;$i < 4;$i++){
if(($arr[$i] <'0') || ($arr[$i] > '255')){
return false;
}
}
}
return true;
