Insert some posts in a loop - wordpress plugin - wordpress

Question

I wrote a plugin, which reads csv files and create new products. The plugin works when I create only one product but when I add while in Insert() the plugin doesn't work. I want to create all products first off. Maybe it's something related to the add_action... Please help.
define( 'PLUGIN_DIR', dirname(__FILE__).'/' );
function CreateProduct($line) {
$data = explode('";"', $line);
define(POST_NAME, $data[2]);
define(cena_netto_pw, $data[5]);
$post = get_page_by_title( POST_NAME, 'OBJECT', 'product' );
$product_ID = $post->ID;
$post_data = get_post($product_ID);
function hbt_create_post() {
$my_post = array(
'post_title' => POST_NAME,
'post_content' => '',
'post_status' => 'publish',
'post_author' => 1,
'post_type' =>'product'
);
$product_ID = wp_insert_post( $my_post );
}
if(!isset($post))
hbt_create_post();
return $error_obj;
}
function Import() {
$file = PLUGIN_DIR.'test.csv';
$open = fopen($file, 'r');
while (!feof($open)) {
$line = fgets($open);
CreateProduct($line);
}
fclose($open);
}
add_action('admin_init', 'Import' );
?>
While loop code
while (!feof($open)) { $line = fgets($open); CreateProduct($line); }
This code doesn't work. It works when there is only
$line = fgets($open); CreateProduct($line);

Answer 1

try
fgetcsv($open)
instead
fgets($open)
