//思路比较简单，用户填写自己的信息，并上传图像（后台生成缩略图），然后图像可以立即无刷新的回显

下面这个事上传和缩略图的类，比较简单：

<?php 
require_once "sql.tool.php";
class Picture

	//上传文件
	private $upfile;
	//保存后的源文件
	private $img;
	//上传文件的类型
	private $fileType;
	//上传图片保存的路径
	private $path;
	//上传图片的名字
	private $fname;
	//缩略图的宽度
	private $width;
	//缩略图的高度
	private $height;
	
	//错误信息
	private $noticeMsg=null;
	private $sql;
	public function __construct($upfile)
	{
		$config = require "config.php";
		$this->width=$config['image']['width'];
		$this->height=$config['image']['height'];
		if(is_uploaded_file($upfile['tmp_name']))
		{
			$this->upfile = $upfile;
		}
		else
		{
			$this->noticeMsg = '非法文件';
		}
		$this->sql = new Sql();
		$this->moveFile();
		$this->zoomInPic();
		echo "<script> parent.document.getElementById('feedback').innerHTML='{$this->noticeMsg}'</script>";
	}
	private function checkFilesStatus()
	{
		//上传失败,分析原因
		if($this->upfile['error']>0)
		{
			switch($this->upfile['error'])
			{
				case 1:
					//超过表单定义的MAX_FILE_SIZE
					$this->noticeMsg = '文件太大';

			}
			return 0;
		}
		else
		{//上传成功
			$this->noticeMsg = '上传成功';
			return 1;
		}
	}
	//检测上传文件类型
	private function checkFileType()
	{
