Php文件上传类class.upload.php用法示例

<form enctype="multipart/form-data" method="post" action="upload.php">

   <input type="file" size="32" name="image_field" value="">

   <input type="submit" name="Submit" value="upload">

 </form>

$handle = new upload($_FILES['image_field']);

   if ($handle->uploaded) {

//这个判断是个安全选项，看一下这个文件真的是正规途径过来的上传文件吗。

       $handle->file_new_name_body   = 'image_resized';//给这个文件起个名字吧， 注意这个是不带扩展名的部分，如果有与之同名的文件，默认的行为是重命名。

       $handle->image_resize         = true;//我们传了一张图片，需要对它进行缩放，设置缩放属性为true

       $handle->image_x                  = 100;//缩放要有标准，这里我们以宽度为基准，宽度必须是100像素

       $handle->image_ratio_y        = true;//你也可以指定一个具体的长度数值，写法是$handle->image_y = [数值]，这里是告诉程序以宽度为基准，高度按比例缩放。

       $handle->process('/home/user/files/');//在执行这句话之前，你还可以设定更多的处理选项，比如是否对图 片进行旋转剪裁，设定好了，就用这句话来执行图片处理和上传。图片处理时会创建一个原图片的副本，不会修改原始文件，原始文件存在于php的临时文件夹 中，在linux服务器上可能是/tmp目录。这样你可以对同一张上传的图片进行多次处理，并指定上传到不同的位置。这里'/home/user /files/'指定了文件要被复制到的位置。

       if ($handle->processed) {

           echo 'image resized';

           $handle->clean();//如果文件成功上传，就清除掉这个对源文件的引用，此后将不能再对刚才上传到临时文件夹的图片进行处理和复制了。

       } else {

           echo 'error : ' . $handle->error;

       }

   }

$handle = new upload($_FILES['image_field']);
