适用于初学者的简易PHP文件上传类

本文实例讲述了PHP多文件上传类，分享给大家供大家参考。具体如下：

_destination = $path;
    $this->_uploaded = $_FILES;
  }
  
  public function move(){
     
    $filed = current($this->_uploaded); 

    $isOk = $this->checkError($filed['name'], $filed['error']);
    //debug ok
    if ($isOk){
      $sizeOk = $this->checkSize($filed['name'], $filed['size']);
      $typeOk = $this->checkType($filed['name'], $filed['type']);
      if ($sizeOk && $typeOk){
  
 $success = move_uploaded_file($filed['tmp_name'], $this->_destination.$filed['name']);
  
 if ($success){
   $this->_messages[] = $filed['name']."文件上传成功";
 }else {
   $this->_messages[] = $filed['name']."文件上传失败";
 }
      }

    }
  }
  
  public function getMessages(){
    return $this->_messages;
  }
   
  
  public function checkSize($filename, $size){
     
    if ($size == 0){
      return false;
    }else if ($size > $this->_max){
      $this->_messages[] = "文件超出上传限制大小".$this->getMaxsize();
      return false;
    }else { 
      return true;
    }
  }
   
  
  protected function checkType($filename, $type){
    if (!in_array($type, $this->_permited)){
      $this->_messages[] = "该文件类型是不被允许的上传类型";
      return false;
    }else {
      return true;
    }
  }
   
  
  public function getMaxsize(){
    return number_format($this->_max / 1024, 1).'KB';
  }
   
  
  public function checkError($filename, $error){
    switch ($error){
      case 0 : return true;
      case 1 :
      case 2 : $this->_messages[] = "文件过大！"; return true;
      case 3 : $this->_messages[] = "错误上传文件！";return false;
      case 4 : $this->_messages[] = "没有选择文件!"; return false;
      default : $this->_messages[] = "系统错误!"; return false;
    }
  }
}
?>
