LOAD DATA LOCAL INFILE forbidden

Hello fellow Yii'ers!

I am running an xampp stack on top of a windows machine for local development and attempting to load large batch files into mysql. I have been essentially following this tutorial:

Importing CSV file to mysql table using "LOAD DATA" command

My code looks a little like this:

$sql = 'LOAD DATA LOCAL 
            INFILE "' . $tempLoc . '"
            INTO TABLE charges
            FIELDS
                TERMINATED BY ","
                ENCLOSED BY "\'"
            LINES
                TERMINATED BY "\\n"                                
                (
                    id, 
                    loc, 
                    chgs, 
                    post_dt
                    )';

$connection = Yii::app()->db;
$transaction = $connection->beginTransaction();
try {

    $connection->createCommand($sql)->execute();
    $transaction->commit();
} catch (Exception $e) { // an exception is raised if a query fails
    print_r($e);
    exit;
    $transaction->rollBack();
}

When I load the file I get this error:

"PDOStatement::execute() [<a href='pdostatement.execute'>pdostatement.execute</a>]: LOAD DATA LOCAL INFILE forbidden"

I have followed the advice given here Load data local infile MySQL does not work by adding the attribute option into my db connection as such:

'db'=>array(
  'connectionString' => 'mysql:host=localhost;dbname=...',
  'username' => '...',
  'password' => '...',
  'attributes'=>array(
    PDO::MYSQL_ATTR_LOCAL_INFILE
  ),
),

I have also added the following line to my.ini file, under [mysqld]:

local-infile=1

These setting have not changed the error at all. I have searched for an answer, but I have not been able to resolve the issue. I should also mention, if I run the same sql statement within phpMyAdmin, it works flawlessly. I'm hoping someone more knowledgeable about this issue may be able to assist me. Thank you!
