Multiple Arguments

• Extra arguments are ignored, but can be retrieved:

<?php
   function some_func($a, $b) {
      for ($i = 0; $i < func_num_args(); ++$i) {
         $param = func_get_arg($i);
         echo "Received parameter $param.\n";
      }
   }

   function some_other_func($a, $b) {
      $param = func_get_args();
      $param = join(", ", $param);
      echo "Received parameters: $param.\n";
   }

   some_func(1,2,3,4,5,6,7,8);
   some_other_func(1,2,3,4,5,6,7,8);
?>
