When accessing member variables and methods you do not include a $ with the variable name.

$this->link=mysql_connect($hostname,$dbusername,$dbpass);

$this->thisquery=$query;

i remove $ and get new error :

Fatal error: Call to undefined method DBconnector::query() in C:\xampp\htdocs\cms-project\index.php on line 5

 

and this is my index.php code :

 

<?php
require_once('include/DBconnector.php');
$connectdb=new DBconnector();
$result=$connectdb->query("SELECT username FROM userinfo");
$row=$connectdb->fetchquery($result);
echo $row['username'];
?>

You never close your constructor function, until the end of the class.
