how to bind multiple parameters to MySQLi query [closed]

I have a mysql query, but I can't bind param for it

SELECT users.email,users.handle,userprofile.mobile FROM users,userprofile WHERE users.email =? OR users.handle =? OR userprofile.mobile=?

I've tried below line

$query = "SELECT users.email,users.handle,userprofile.mobile FROM users,userprofile WHERE users.email =? OR users.handle =? OR userprofile.mobile=?";
$stmt = $mysqli->prepare($query);
$stmt->bind_param("sss",$email,$username,$mobile);
if ($stmt->execute()) {
if($stmt->num_rows){ echo '......'; }
}

but I've received and error :

Warning: mysqli_stmt::bind_param(): Number of elements in type definition string doesn't match number of bind variables

This is the correct syntax for binding params in mysqli

$SQL = "SELECT users.email, users.handle, userprofile.mobile FROM users,userprofile WHERE users.email =? OR users.handle =? OR userprofile.mobile=?";
$stmt = $mysqli->prepare($SQL);
$stmt->bind_param("sss", $one,$two,$three);
$stmt->execute();
//do stuff

Try this...

$stmt = $dbConn->prepare("SELECT users.email,users.handle,userprofile.mobile FROM users,userprofile WHERE users.email = ? OR users.handle = ? OR userprofile.mobile= ?");
$stmt->bind_param("sss", $email, $handle, $mobile);
$stmt->execute();
