Description:
------------
Hi,
When i use spl_autoload_register(), when i use $mdb2->quote('hello','text');
the MDB2::isError function use function is_a($data) and trigger a call to spl_autoload_register() with string value as classname ;-)
below code for check
Test script:
---------------
class c_autoloader {
public function __construct() {
spl_autoload_register(array($this, 'loader'));
}
private function loader($className) {
echo 'Trying to load ', $className, ' via ', __METHOD__, "()<br />\n";
$a = debug_backtrace(false);
print_r($a);
include($className . '.php');
}
}
$autoloader = new c_autoloader();
function dbConnect($dsn) {
$options = array(
'debug' => 2,
'result_buffering' => false,
);
$mdb2 =& MDB2::connect($dsn, $options);
if (PEAR::isError($mdb2)) {
die('connexion:'.$mdb2->getMessage());
}
$mdb2->setFetchMode(MDB2_FETCHMODE_ASSOC);
return $mdb2;
}
$mdb2 = dbConnect('your dsn');
$username = 'myusername';
$sql = 'SELECT * FROM users WHERE username='.$mdb2->quote($username);
$stmt = $mdb2->query($sql);
Expected result:
----------------
in fact, to block this, it's really easy with if check in replacement of original. gettype($data)=='object' check if this var is an object
function isError($data, $code = null)
{
if (!gettype($data)=='object' || !is_a($data, 'PEAR_Error')) {
return false;
}
Actual result:
--------------
