Access model from Thread in Yii - php

Question

I have to parse a huge csv files in a Yii 1.1 Application.
Each row has to be validated and saved to the database.
I decided to use Multi Threading for this task.
So here is my code in the Controller action:
public function parseData($) {
$this->content = explode("\n", $this->content);
$thread_1 = new DatalogThread(array_slice($this->content, 0, 7000));
$thread_2 = new DatalogThread(array_slice($this->content, 7001));
$thread_1->start();
$thread_2->start();
}
And the Thread (I put it in models folder):
class DatalogThread extends Thread {
public $content;
public function __construct($content) {
$this->content = $content;
}
public function run() {
foreach ($this->content as $value) {
$row = str_getcsv($value);
$datalog = new Datalog($row);
$datalog->save();
}
}
}
The problem is that the Thread does not get access to the model file:
Fatal error: Class 'Datalog' not found in C:\xampp...\protected\models\DatalogThread.php
I tried Yii::autoload("Datalog"), but got The following error:
Fatal error: Cannot access property Yii::$_coreClasses in ...\YiiMain\framework\YiiBase.php on line 402

Yii uses a LOT of statics, this is not the best kind of code for multi-threading.
What you want to do is initialize threads that are not aware of Yii and reload it, I do not use Yii, but here's some working out to give you an idea of what to do:
<?php
define ("MY_YII_PATH", "/usr/src/yii/framework/yii.php");
include (MY_YII_PATH);
class YiiThread extends Thread {
public $path;
public $config;
public function __construct($path, $config = array()) {
$this->path = $path;
$this->config = $config;
}
public function run() {
include (
$this->path);
/* create sub application here */
}
}
$t = new YiiThread(MY_YII_PATH);
$t->start(PTHREADS_INHERIT_NONE);
?>
This will work much better ... I should think you want what yii calls a console application in your threads, because you don't want it trying to send any headers or anything like that ...
That should get you started ...
