Unfortunately, when I put the variable name with a dot, it is not possible to read it in php and it does not show anything. Please see the code.

if (isset($_GET['submit'])) {
    $show= $_GET['input_18.1']." " .$_GET['input_18.2'];
    echo($show);
}
?>

<form method="get">
    <input name="input_18.1">
    <input name="input_18.2">
    <input type="submit" name="submit">
</form>

Why do you want to use it if you know the dot is a problem? – KIKO Software Jul 09 '23 at 14:35
Unfortunately, dot is used in JavaScript code and cannot be changed. Is it possible to display the information? – Mohammad Mahdavi Jul 09 '23 at 14:52

Have you tried to figure out, what you're getting in `$_GET`? For example, using `var_dump($_GET)` – akrys Jul 09 '23 at 14:56
