When using a class method as a callback for functions like array_map() and usort(), you have to send the callback as two-value array. The 2nd value is always the name of the method as a string. The 1st value is the context (class name or object)

// Static outside of class context
array_map( array( 'ClassName', 'methodName' ), $array );

// Static inside class context
array_map( array( __CLASS__, 'methodName' ), $array );

// Non-static outside of object context
array_map( array( $object, 'methodName' ), $array );

// Non-static inside of object context
array_map( array( $this, 'methodName' ), $array );
