Hi,
In the static function "toHtml_table_heading" I want to use a static array $fields, which is defined differently in each implementation.
My first trial was to use self::$fields[] to access this array, but this only sees the member of DBTable, not the inherited from DBTable.
My second trial was to pass the classnmae thru $classname and to access the correct $fields with $classname::$fields, but that doesn't seem to work.
abstract class DBTable {
static protected $fields = array();
static function toHtml_table_heading($classname) {
$fields = $classname::$fields; // <== syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM
//...
}
//...
}
class DBImplementation extends DBTable {
public function intializeClass() {
self::$fields[] = new Object(1);
self::$fields[] = new Object(2);
}
function __construct() {
intializeClass()
}
