how to bind multiple parameters to MySQLi query [closed]

Answer 1

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();

Answer 2

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=?";

if ($stmt = $mysqli->prepare($SQL)) {

     $stmt->bind_param("sss", $one,$two,$three);
     $stmt->execute();

     //do stuff
}
