复制代码 代码如下:

$uid=$_REQUEST['uid'];

$avatar = 'D:/avic/discuz/uc_server/data/avatar/'.get_avatar($uid, $size, $type);
$dir=dirname($avatar);

//创建目录成功后移动临时文件
if(mkdirs($dir)){
  if($_FILES["pic"]["error"] >= 0){
    if(move_uploaded_file($_FILES['pic']['tmp_name'],$avatar)){
      $errorcode=1;
    }else{
      $errorcode=0;
      $errormsg="文件移动失败";
    }
  }else{
    $errorcode=0;
    $errormsg=$_FILES['pic']['error'];
  }
}
$back=array("errorcode"=>$errorcode,'errormsg'=>$errormsg);
echo json_encode($back);

//返回图片要存储的路径
function get_avatar($uid, $size = 'middle', $type = '') {
  $size = in_array($size, array('big', 'middle', 'small')) ? $size : 'middle';
  $uid = abs(intval($uid));
  $uid = sprintf("%09d", $uid);
  $dir1 = substr($uid, 0, 3);
  $dir2 = substr($uid, 3, 2);
  $dir3 = substr($uid, 5, 2);
  $typeadd = $type == 'real' ? '_real' : '';
  return $dir1.'/'.$dir2.'/'.$dir3.'/'.substr($uid, -2).$typeadd."_avatar_$size.jpg";
}
//递归创建目录,若传的$dir不是绝对路径,则会和运行此方法的目录同级
function mkdirs($dir){
  if(!is_dir($dir)){
    if(!mkdirs(dirname($dir))){
      return false;
    }
   if(!mkdir($dir,0777)){
      return false;
    }
   }
return true;
}
?>
