how to compare array for single result using if statement

Question

i was doing validation for user form after each validation i used to store "valid" in a array index and at last comparing them like this:

 if(isset($fullname)){
    if ($valid["name"]=="valid"&&$valid["username"]=="valid"&&$valid["password"]=="valid"&&$valid["email"]=="valid") {
            session_start();
            $_SESSION["reg_name"] = $fullname1;
            $_SESSION["reg_username"] = $username1;
            $_SESSION["reg_email"] = $email1;
            $_SESSION["reg_password"] = $password1;
            $_SESSION["reg_gender"] = $_REQUEST['gender'];
            header("location:validation&insertion.php");
    }

Well i will check validation and then make session .

My question is there any short way to check the whole array across a single value like "valid"? I hope you have understand my question.Comment it if it is not asked well. Do not rate as negative.Please ignore my grammar mistakes.I hate those who edit my question's grammar.

it's value will be not valid i am storing by using if else if regex matches then set value to "valid" else set to "notvalid" — Awais Ahmad

You can just count the number of unique values and check if it's equal to 1, then check one value if it is "valid".

if (count(array_unique($valid)) === 1 && $valid["name"] === "valid") {
    session_start();
    $_SESSION["reg_name"] = $fullname1;
    $_SESSION["reg_username"] = $username1;
    $_SESSION["reg_email"] = $email1;
    $_SESSION["reg_password"] = $password1;
    $_SESSION["reg_gender"] = $_REQUEST['gender'];
    header("location:validation&insertion.php");
}

Or just simply check if a "notvalid" value is found in the array:

if (!in_array("notvalid", $valid)) {
    session_start();
    $_SESSION["reg_name"] = $fullname1;
    $_SESSION["reg_username"] = $username1;
    $_SESSION["reg_email"] = $email1;
    $_SESSION["reg_password"] = $password1;
    $_SESSION["reg_gender"] = $_REQUEST['gender'];
    header("location:validation&insertion.php");
}

@AwaisAhmad The first part is an alternative though, if you will have another value assigned other than "notvalid". Anyways, no problem.
