PHP json_encode mysql结果

Question

我有一个简单的mysql_query，我想results(title= > $title, price => $price etc)在json中编码。

$ sql = mysql_query（“ SELECT * FROM item_details WHERE posts_id ='$ item_number'”）;

 while（$ row = mysql_fetch_array（$ sql））
{
   $ title = base64_decode（$ row ['title']）;
   $ price = $ row ['price'];
   $ seller_user = $ row ['user'];
}

Answer 1

$sql = mysql_query("SELECT * FROM item_details WHERE posting_id='$item_number'");
$results = array();
while($row = mysql_fetch_array($sql))
{
   $results[] = array(
      'title' => base64_decode($row['title']),
      'price' => $row['price'],
      'seller_user' => $row['user']
   );
}
$json = json_encode($results);
