Introduction

This function checks if an input-value is an IP-adresse or not. It makes use of the regular-expression function preg_match.

<?php

function IsIPAdress($value){
    
    if (preg_match('/^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$/', $value)){
        return true;
    }
    return false;
}

if( IsIPAdress("192.168.0.1") )
    echo("This is an IPAdress");
else
    echo("This is not an IPAdress");

?>
