Question

how can i convert it into float and then increment it and then convert back to string.

if($set==$Data_Id)
{
$rel='1.1.1.2';
}

after increment it should be like 1.1.1.3.

Please any help.

“1.1.1.2” is not a valid number. So you’ll have to do something like this:

$rel = '1.1.1.2';
$relPlusOne = increment($rel);
function increment($number) {
    $parts = explode('.', $number);
    $parts[count($parts) - 1]++;
    return implode('.', $parts);
}
