Bug #34785 Can not properly subclass mysqli_stmt
Submitted: 2005-10-08 01:11 UTC Modified: 2005-10-08 17:09 UTC
From: squasar at eternalviper dot net Assigned: georg
Status: Closed Package: MySQLi related
PHP Version: 5CVS-2005-10-08 (cvs) OS: *
Private report: No CVE-ID:
 [2005-10-08 01:11 UTC] squasar at eternalviper dot net
Description:
------------
If mysqli_stmt is subclassed (only makes sense in PHP 5.1.0 or 
above), calling parent::__construct() results in "Fatal error: 
Can not call constructor".

Fix:
Index: ext/mysqli/mysqli_fe.c
==============================================================
=====
RCS file: /repository/php-src/ext/mysqli/mysqli_fe.c,v
retrieving revision 1.49
diff -r1.49 mysqli_fe.c
285a286
>       PHP_FALIAS(mysqli_stmt,mysqli_stmt_construct,NULL)


Reproduce code:
---------------
<?php
class my_stmt extends mysqli_stmt {
 public function __construct( $link, $query ) {
  parent::__construct( $link, $query );
 }
}
$conn = new mysqli;
$stmt = new my_stmt( $conn, "SELECT 1 FROM DUAL" );
var_dump( $stmt );
?>

Expected result:
----------------
object(my_stmt)#2 (0) {
}

Actual result:
--------------
Fatal error: Can not call constructor in - on line 4
