The following function compares two ip-adresses.
On match it returns true, otherwise false.
<?php
function compare_ip($ipreg,$ip) {
$ipreg = explode('.',$ipreg);
$ip = explode('.',$ip);
for ($i = 0; $i < 4; $i++) {
if ($ipreg[$i] != $ip[$i] && $ipreg[$i] != '*') return false;
}
return true;
}
?>
Examples:
<?php
var_dump(compare_ip('123.121.144.1','123.121.144.2')); // false
var_dump(compare_ip('123.121.144.1','123.121.144.1')); // true
var_dump(compare_ip('123.121.144.*','123.121.144.23')); // true
var_dump(compare_ip('123.121.*.*','123.121.2.4')); // true
?>
Have fun :)
