PHP的回声JSON在foreach循环
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);
}

答
$product_ids = explode(',', $product_ids);
$product_ids = array_filter($product_ids);
$final_data = array();
foreach ($product_ids as $key => $product_id) {
$sth = $this->db->prepare("SELECT * FROM products Where id =:id ");
$sth->execute(array( ':id' => $product_id ));
$final_data[$product_id] = $sth->fetchAll();
}
echo json_encode($final_data);
