The Zend Framework proved to be:

I’ve narrowed the issue down to PDO itself and not the Zend Framework.

$dbh = new PDO("mysql:host=localhost;dbname=db","user","pw"); $query = "insert into silo_test_data (record_id, fieldname, value) . . . → Read More: Zend Framework and PDO_MYSQL]]> I’ve been working with the Zend Framework a bit and in working with MySQL through PDO_MYSQL. I’ve run into a few problems trying to use parameters of queries.

I’ve narrowed the issue down to PDO itself and not the Zend Framework.


$dbh = new PDO("mysql:host=localhost;dbname=db","user","pw");
$query = "insert into silo_test_data (record_id, fieldname, value)
values (3,'stufftest', :value )";
$handle = $dbh->prepare($query);
$handle->execute(array(":value" => 'crap'));
$dbh = null;


The value gets inserted into the database as an empty string, or sometimes some low-value bytes. I’ve managed to work around this temporarily thanks to some help from this post. By setting PDO to emulate prepared statements, everything seems to work okay.


$dbh->setAttribute(PDO::ATTR_EMULATE_PREPARES, true);


The problem is, the Zend framework encapsulates the actual db connection and connects lazily. So, for now I’m running a query and then set the parameter on the encapsulated connection object.


$db_connect = array( 'host' => $config->db->hostname,
'username' => $config->db->username,
'password' => $config->db->password,
'dbname' => $config->db->database );
$db = Zend_Db::factory('PDO_MYSQL', $db_connect);
$db->query('select 1');//HACK HACK HACK HACK to initiate connection. Can't I make this a plugin? or extend the class?
$db->getConnection()->setAttribute(PDO::ATTR_EMULATE_PREPARES, true);
Zend::register('db',$db);


I look forward to contributing more and more to the discussion and ultimately contribute patches and code going forward.

For example, in the preview release, . . . → Read More: Getting Closer to the Zend Framework]]> I’ve subscribed to the mailing list for the new Zend Framework. It’s been quite enlightening to be thrown into a community of the highest-caliber PHP developers (aside from my team of course).

I look forward to contributing more and more to the discussion and ultimately contribute patches and code going forward.

For example, in the preview release, I’ve been working with the Zend_Controller and found a number of things that it lacks. This in and of itself is no problem. The framework is supposed to include some of the best solutions for the most common problems. The aspect I’d like to improve is to allow the framework to be a bit more extensible. For example, there’s no easy way to change the parsing of the actual URL. Even by overloading the functions I still have to pass the URL in via a global variable.

It’s very lucky that we just finished rewriting our front-controller. We learned lots of lessons in the process, but ours solves a specific problem and wouldn’t be for everyone.
