With the $this->$my_value = .. syntax, you set the property with the name of the value in $my_value. What you want is $this->my_value = .. $var = "my_value"; $this->$var = "test"; is the same as $this->my_value = "test"; To fix a few things from your example, the code below is a better aproach class my_class { public $my_value = array(); function __construct ($value) { $this->my_value[] = $value; } function set_value ($value) { if (!is_array($value)) { throw new Exception("Illegal argument"); } $this->my_valu

I've following class for users: class Users { private $host = DB_HOST; private $user = DB_USERNAME; private $pass = DB_PASSWORD; private $dbname = DB_NAME; private $conn; private $stmt; public $error; function __construct() { $dsn = 'mysql:host='.$this->host.';dbname='.$this->dbname.';charset=utf8'; $options = array( PDO::ATTR_PERSISTENT => true, PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION ); try { $this->conn = new PDO($dsn,$this->user,$this->pass,$options); } catch (PDOException $e) http://stackoverflow.com/questions/21657566/cannot-access-empty-property-php-class { $this->error = $e->getMessage(); } } private function mysql_execute_query($sql,$params) { $this->stmt = $this->conn->prepare($sql); $this->stmt->execute($params); return $this->$stmt; } public function find_user_by_provider_uid($provider,$provider_uid) { $sql = 'SELECT * FROM users WHERE provider = :provider AND provider_uid = :provider_uid LIMIT 1'; $params = array( ':provider' => $provider, ':provider_uid' => $provider_uid ); $result = $this->mysql_execute_query($sql,$params); return $result->fetch(); } } First of all is there some tip that comes to mind for structuring this code better? or using more features of oop? Second, it fails with following error: PHP Notice: Undefined variable: stmt PHP Fatal error: Cannot access empty property Both of this lines refer to return $this->$stmt; inside mysql_execute_query My hunch is that it has something to do with it being private function. But I cannot tell. Any ideas? php oop share|improve this question asked Feb 9 '14 at 9:47 salivan 1,84184394 You used $this->stmt in one case and $this->$stmt in another.

appear before object properties. In contrast: $b; // WRONG !!! } } // Using the class $myObject = new A(); echo $myObject-$get_b(); // WRONG!!! ?> the above code segment is wrong. You should use $ only once - before ‘ this' only. No need to use $ sign before class variables or methods. Correct version of the above code segment: b; } } // Using the class $myObject = new A(); echo $myObject-get_b(); ?> Share this:TweetMore Related Posted on November 14, 2010Author Shafiul AzamCategories PHP, Web DevelopmentTags Cannot access empty property 4 Comments Post navigation PreviousC style For loop in PythonNextPython MySQLdb equivalent for PHP's mysql_insert_id() 4 thoughts on “PHP Fatal error: Cannot access empty property in” Tom says: May 26, 2011 at 9:50 pm Good job man.
