Codeigniter: query builder select, insert, update and delete

Query table:
        $this->result = $this->db->get('ca_brand',$mmax, 0);
        if ($this->result) {
            return true;
        } else {
            return false;
        }
Query table with like filter:
        $this->db->like('name', $keyword); // buildin mysql escape
        $this->result = $this->db->get('ca_brand',0, $mmax);
        if ($this->result) {
            return true;
        } else {
            return false;
        }
 Insert row in table:
        // buildin mysql escape character
        $data = array('name' => $name);
        $this->db->insert('ca_brand', $data); // return true on success

        $insert_id = $this->db->insert_id(); // get id

Update row in table for spesific id
        // buildin mysql escape character
        $id = intval($id);
        $data = array ('name' => $name);
        $this->db->where('id', $id);
        //$this->db->update('ca_brand',$data, "id = "$id ); // option 1
        $this->db->update('ca_brand',$data); // // option 2
        $numaffectedrow = $this->db->affected_rows(); // to get nummber affected row
 Delete row:
        $id = intval($id);
        $this->db->where('id', $id);
        $this->db->delete('ca_brand');
        $numaffectedrow = $this->db->affected_rows(); // to get nummber affected row

Codeigniter: check mysql connection

To check error in mysql connection, we need to change ENVIRONMENT to Production. Here is the example:
    //define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'development');
    //define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'testing');
    define('ENVIRONMENT', isset($_SERVER['CI_ENV']) ? $_SERVER['CI_ENV'] : 'production');
There are two ways to catch error in our controller:
1. Using dblib
        $this->load->dbutil();
        if ($this->dbutil->database_exists('myca')) {
            // Connection ok
        } else {
            // Connection fail
        }
2. Checking error in db
        $this->load->database();
        $errhandle = $this->db->error();
        if ($errhandle['code']==0) {
            // Connection ok
        } else {
            // Connection fail
            // to dump error code var_dump( $this->db->error());
        }

windows: kill process by id using cmd

The most old games do not run on Windows 10. For example Red Alert and GTA San Andreas. Those games require DirectPlay in Windows 10 (legacy feature.

Before you try your old games you need to run cmd in administrator mode. In case the game does not play properly, switch to cmd and stop the game.
