xxxx-xxxx-xx

how can i do this with php or jquery ?

Answer 1

$code = "1234567890";
echo substr($code, 0, 4) . "-" . substr($code, 4, 4) . "-" . substr($code, 8, 2);

Answer 2

You can use Regular Expression.

$Text        = "1234567890";
$Pattern     = '/(.{4})(.{4})(.{2})/';
$Replacement = '$1-$2-$3';
$NewText     = preg_replace($Pattern, $Replacement, $Text);

Hope this helps.

Answer 3

in jquery, for example:

<script>
    $(document).ready(function(){
        n = $("#IdOfTheElement").text();
        n = n.substr(0, 4) + "-" + n.substr(4, 4) + "-" + n.substr(8);
        $("#IdOfTheElement").text(n)
    }
</script>
