请问在php里, 从mysql读到的图片, 要怎么存成本地的pic呢?
mysql里我是把jpg图片用mediablob的格式存的.

显示我可以用:
  $showidxnumber=$_GET["idx_num"];
  $result=mysql_query("SELECT * FROM ecard WHERE picidx=$showidxnumber");
  $row=mysql_fetch_object($result);
  echo $row->picdata;   

但目前有个新的需求, 要把pic存到本地, 比如把它save成c:\a.jpg  ,要怎么写code呢? 请教一下大家, 谢谢了.

php mysql
------解决方案--------------------
file_put_contents('c:\a.jpg', $row->picdata);
