Note Submitter: rasto_klc (at) yahoo (dot) obvious ---- Variable-length argument lists in abstract methods will generate fatal error if derived. Here is an simple example: <?php // common wrap for all validators is forcing uniform interface abstract class ValidatorWrap { // just example why variable-length arguments are needed public function __construct() { if (func_num_args() > 0) { $arg_list = func_get_args(); call_user_func_array(array(&$this, 'setupValidator'), $arg_list); } else { $this->setupValidator(); } // continue with construction } // amount of arguments is specific to validator implementation abstract public function setupValidator(); // known interface abstract public function validate($value); } class Validator1 extends ValidatorWrap { protected $pattern = ''; // this will generate PHP Fatal error because $pattern is not expected public function setupValidator($pattern) { $this->pattern = $pattern; } // this will do OK public function validate($value) { return preg_match($this->pattern, $value); } } // make numeric validator $validator = new Validator1('/^\d+$/'); echo (int) $validator->validate($_REQUEST['digits']); ?> I need it to work so I just redefine troublemaking function as follows: <?php public function setupValidator() { } ?> This will give me functionality I need and generates only PHP Strict Standards warning.
