PHP PDO错误语法

Can someone help me:

I got error when i write this

$check = $db->prepare("SELECT email FROM user WHERE email = ?");
if($check->rowCount() == 1){
    $error = "<div class ='text-danger'> Email Telah Digunakan </div>"; 
} else {
    $code = rand();
    $status = 0;
    try{
        $query = $db->prepare("INSERT INTO users(first_name,last_name,email,password,gender,code,status) VALUES (?,?,?,?,?,?,?,)");
        $query->execute([$first_name,$last_name,$email,password_hash($password,PASSWORD_DEFAULT),$gender,$code,$status]);   
    }
    catch(PDOException $e){
        echo"error:  " .$e->getMessage();
    }
}

Ok, so you have a , at the end of your VALUES()'s list without something after it, which would lead to such syntax error. Here is the fixed version:

$check = $db->prepare("SELECT email FROM user WHERE email = ?");
if($check->rowCount() == 1){
    $error = "<div class ='text-danger'> Email Telah Digunakan </div>"; 
}else{
    $code = rand();
    $status = 0;
    try{
        $query = $db->prepare("INSERT INTO users(first_name,last_name,email,password,gender,code,status) VALUES (?,?,?,?,?,?,?)");
        $query->execute([$first_name,$last_name,$email,password_hash($password,PASSWORD_DEFAULT),$gender,$code,$status]);
    }
    catch(PDOException $e){
        echo "error:  " .$e->getMessage();
    }
}

You where also missing a closing bracket for the if statement. Or maybe you copied wrongly. I've not actually checked full functionality, just the syntax errors I could find.

A small tip

If you format your code properly, you can find syntax errors a lot easier. A good code editor also helps.
