As pointed out earlier by our lord and savior Matthew O'Phinney, Zend\Di is
becoming less desired component in favor of ServiceManager.
Works for me. I agree SM is much easier to use, except in one instance. So
I turn to the community to help me resolve this one instance:
> How do I get a ServiceManager object with __constructor() parameters?
My dilemma: I'm building a super-small application with very limited
requirements that is dependent on PDO.
However, PDO requires constructor parameters. How do I create a PDO loader
that can 1) be cached by PHP5.5 opcode 2) doesn't require a bunch of other
classes and 3) can be loaded only at the time I need to make a PDO call.
(speed of application is #1 requirement)
$sm->get('PDO'); doesn't work since I can't pass in construction parameters.
$sm->get('Db'); won't work either, since construction parameters exist
within the same file the closure would be included:
```
app.config.php = [
'sm' => array(
"factories" => array(
'Db' => function ($sm) {
(PS: Are these cached now? I recall some caching issues
with embedded closures)
// $sm->get('Config'); is invalid; not using
Zend\Application that would inject this.
//return new PDO(); // No way to get construct parameters
below...
},
)
),
// ....
"db" => [
"dsn" =>
'cassandra:host=127.0.0.1;port=9160,host=127.0.0.2;port=9162;version=3.0.0;dbname=test',
"username" => null,
"password" => null,
],
];
```
For Di, I could pass in the parameters: $di->get('PDO', $cfg['db']);
This isn't possible for SM. This little functionality would make a world of
difference.
