Question

class User extends DatabaseObject {

    protected static $table_name='users';
    protected static $db_fields = array();

public  function __construct() {

    // Get columns from table
    global $database;
    $result_set = $database->query("SELECT * FROM ".self::$table_name." LIMIT 1");
    $num_fields = mysql_num_fields($result_set);
    for($i=0; $i<$num_fields; $i++) {
        $column_name = mysql_field_name($result_set, $i);
        // Set column names as variables
        self::$db_fields[] = $column_name; // THIS WORKS
    $this->{$column_name}; // THIS IS PROBLEMATIC!

  }

}

for example this $name = pulic $wherever;
so I can call, for example, wherever->wherever;

so that I don’t have to type this name every time I add the variables

public $md5;
public $credit;
public $pontaria_time;
public $Credits;
public $airoplayne;
public $city_id;
public $prisao_time;
public $crime2;
public $banck_time;

Answer 1

 $this->{$column_name}; // THIS IS PROBLEMATIC!

You need to use

$this->$column_name = $column_value

OR you can write all columns in $db_fields field and add

public function __get($name) {}
