PHP Version 5.1.3RC2-dev 2006-03-19 15:30
WinXP SP2, Apache2 2.0.55

More haywire behaviour when using FETCH_LAZY :

$SQL = new PDO('pgsql:host=localhost;port=5432;dbname=xxxxx', 'user', 'password');

$stmt = $SQL -> query('SELECT ident, descr FROM variables ORDER BY ident');

$stmt -> setFetchMode(PDO :: FETCH_LAZY);

foreach ($stmt as $row) {
  var_dump($row -> ident); (1) // existing column
  var_dump($row -> foo); (2) // non-existant column
}

$SQL = NULL;

The first (2) is garbage, and so are practically all following (1) and (2). At the next page load, Apache crashes. Apache crashes every two page loads in this fashion.

Comment out (1), leaving (2). The first output is NULL, followed by whole PDORows. Apache no longer crashes.

Add, in appropriate locations :

class MyPDOStatement extends PDOStatement { }

$SQL -> setAttribute(PDO :: ATTR_STATEMENT_CLASS, array('MyPDOStatement'));

(1) left commented out. The first (2) is bool(true), the following ones are whole PDORows again. Apache doesn't crash.

Replace those two additions with :

class MyPDOStatement extends PDOStatement {
  private function __construct() { }
}

$SQL -> setAttribute(PDO :: ATTR_STATEMENT_CLASS, array('MyPDOStatement', array()));

Then the first (2) is :

object(MyPDOStatement)#2 (1) {
  ["queryString"]=>
  string(49) "SELECT ident, descr FROM variables ORDER BY ident"
}

and the following are PDORows again. Apache still no longer crashes.
