if(isset($userEmail = $_POST["email"]) && $userEmail = $_POST["email"] != ""){
Here, you are assigning it to a variable and then checking isset all in a single call. Split it up into separate calls:

check if it is set
check if it is not an empty string
validate it against the built-in email validator
assign it to a variable
Likely should be

if(isset($_POST["email"]) && $_POST["email"] != "") {
    if(filter_var($_POST["email"], FILTER_VALIDATE_EMAIL)) {   
        ...
        $userEmail = $_POST["email"];
        ...
