  2. Hi I hope you are well?
    I took my name Victor, I am 22 years in first year of the BTS in Computer Network and Telecom.
    To practice I created a website in php but I have trouble with my database. The liason is there but I can not connect or open an account.
    At first I use MYSQL and when I proceed to the user account login I encounter a problem that I am advised to use MYSQLI or PDO for my database:

    ( ! ) Deprecated: mysql_connect(): The mysql extension is deprecated and will be removed in the future: use mysqli or PDO instead in C:wamp64wwwnewcoredatabaseconnect.php on line 8

    I tried but no change. I do not know what approach to use. If you please, I will send you the site in compressed form by your email so that you can help me. My email is traoregeeker@gmail.com.

    Thank you

    $email = $mysqli->real_escape_string($_POST['email']);
    $password = $mysqli->real_escape_string($_POST['password']);
    $cpassword = $mysqli->real_escape_string($_POST['cpassword']);
    $gender = $mysqli->real_escape_string($_POST['gender']);

    $query = $mysqli->query("SELECT * FROM users WHERE username = '$username'");

    if(empty($username) OR empty($email) OR empty($password) OR empty($cpassword) OR empty($gender)){
    $output = "Please Fill in All Fields.";
    }elseif($query->num_rows != 0){

    $output = "that username already Taken.";
    }elseif ($cpassword !=$password) {
    $output = "Youre password Do'nt Match.";
    }elseif (strlen($password) < 6) {
    $output = "Youre password must be at least 5 characters.";
    }else{
    //Encryption Password
    $password =md5($password);
    //insert the record
    $insert = $mysqli->query("SELECT INTO users (username,email,password,gender) VALUES('$username','$email','$password','$gender')");
    if ($insert != TRUE){
    $output = "There Was a Problem <br />.";

  11. When i reload the page it will automatically inserted last input data
    in the database. If i reload again then it will again inserted last
    input data. Also if i put new data then it inserted the current new
    data. again after inserted new data if i reload the page (without
    giving nothing in the input field) then it automatically inserted last
    new data.
