PHP function return string and variable-CodePudding

I have a PHP function that has to return some string and print variables into the string. Now the function returns a string but does not print variable value.

function listShortcode ($id) {
    $i = $id;
    $html = "<h2>List number";
    $html .= $id;
    $html .= "</h2> <p>other</p>";
    
    return $html;
}

function listShortcode ($id) {
    $i = $id;
    $html = "<h2>List number";
    $html .= $i;
    $html .= "</h2> <p>other</p>";
    
    return $html;
}
