//User … Functions …
function existUsername($dbusername)
{
$this->_dbusername = $dbusername;
global $dbtable,$dbsql,$dbquery;
$dbtable = “users”;
$dbsql = “SELECT * FROM “.$dbtable.” WHERE username = ?”;
$dbquery = $this->_connect->prepare($dbsql);
$dbquery->bind_param(“s”, $this->_dbusername);
$dbquery->execute();
$dbquery->store_result();
if($dbquery->num_rows == 1)
{
echo 1;
}
else
{
echo 0;
}
$dbquery->close();
}
function existEmail($dbemail)
{
$this->_dbemail = $dbemail;
global $dbtable,$dbsql,$dbquery;
$dbtable = “users”;
$dbsql = “SELECT * FROM “.$dbtable.” WHERE email = ?”;
$dbquery = $this->_connect->prepare($dbsql);
$dbquery->bind_param(“s”, $this->_dbemail);
$dbquery->execute();
$dbquery->store_result();
if($dbquery->num_rows == 1)
{
return true;
}

{
return false;
}
$dbquery->close();
}
function UsernameLinkedPassword($dbusername,$dbpassword)
{
$this->_dbusername = $dbusername;
$this->_dbpassword = $dbpassword;
global $dbtable,$dbsql,$dbquery;
$dbtable = “users”;
$dbsql = “SELECT * FROM “.$dbtable.” WHERE username =? AND password =?”;
$dbquery = $this->_connect->prepare($dbsql);
$dbquery->bind_param(“ss”, $this->_dbusername, $this->_dbpassword);
$dbquery->execute();
$dbquery->store_result();
if($dbquery->num_rows == 1)
{
