PHP的回声JSON在foreach循环 [英] php echo json in foreach loop

问题描述

我在$product_ids

$product_ids = explode(',', $product_ids);
$product_ids = array_filter($product_ids);

foreach ($product_ids as $key => $product_id) {

      $sth = $this->db->prepare("SELECT * FROM products Where id =:id ");
      $sth->execute(array( ':id' => $product_id ));
      $final_data = $sth->fetchAll();

      echo json_encode($final_data);
}
