一、文件或图片上传

try {
 if (!is_dir($this->uploadPath)) {
     throw new InvalidArgumentException(‘files.ourats.com还没搭建？‘);
 }

     throw new InvalidArgumentException(‘上传文件夹不可写‘);

     if (!mkdir($cidDirPath, 0777)) {
         throw new InvalidArgumentException("创建$cid文件夹失败");
     }

 // 处理上传文件
 if (!isset($_GET[‘dir‘]) || ($_GET[‘dir‘] != ‘image‘ && $_GET[‘dir‘] != ‘file‘)) {
     throw new InvalidArgumentException(‘无效的参数‘);
 }
 if (!isset($_FILES[‘imgFile‘])) {
     throw new InvalidArgumentException(‘无效的参数‘);
 }
 if ($_FILES[‘imgFile‘][‘error‘] != UPLOAD_ERR_OK) {
     throw new InvalidArgumentException(‘上传失败‘);
 }
 // 如果文件名中有/\,则不接受, .和..也不行
 $filename = trim($_FILES[‘imgFile‘][‘name‘]);

     throw new InvalidArgumentException(‘文件已经存在‘);
 }
 // 由于图片需要显示出来,所以必须严格验证
 $ext = explode(‘.‘, $filename);
 $ext = strtolower(array_pop($ext));
 $mimeTypes = array(
     ‘jpg‘ => ‘image/jpeg‘,

 } catch (InvalidArgumentException $e) {
     $res = array(‘error‘ => 1, ‘message‘ => $e->getMessage());
 } catch (Exception $e) {
     $res = array(‘error‘ => 1, ‘message‘ => ‘未知错误‘);
 }

echo json_encode($res);

二、文件图片的展示[kindeditor中filemanager]

 $ns = new Zend_Session_Namespace(‘DB‘);
 $cid = $ns->cid;
 $baseDir = $this->uploadPath . $cid;

 $imageExts = array(‘jpg‘ => ‘.jpg‘, ‘png‘ => ‘.png‘, ‘gif‘ => ‘.gif‘);
 $onlyImage = $this->getQuery(‘dir‘) == ‘image‘;
 $list = array();
 if (is_dir($baseDir)) {
     $dir = new DirectoryIterator($baseDir);
     foreach ($dir as $fileinfo) {
         if ($fileinfo->isFile()) {
             $isPhoto = isset($imageExts[$fileinfo->getExtension()]);
             if ($onlyImage && !$isPhoto) {
                 continue;
             }
         $filename = $fileinfo->getFilename();
         $args = array($this->token, $cid, $filename);
         sort($args, SORT_STRING);
         $sign = sha1(implode(‘‘, $args));
         $list[] = array(
             ‘uri‘ => ‘cid=‘ . $cid . ‘&file=‘ . urlencode($filename) . ‘&sign=‘ . $sign,
             ‘filename‘ => $filename,
             ‘filesize‘ => $fileinfo->getSize(),
             ‘datetime‘ => date(‘Y-m-d H:i:s‘, $fileinfo->getMTime()),
             ‘is_photo‘ => $isPhoto
         );
     }
 }
 }

if ($list && isset($_GET[‘order‘])) {
     switch ($_GET[‘order‘]) {
     case ‘NAME‘:
         usort($list, function ($a, $b) {
             return strcmp($a[‘filename‘], $b[‘filename‘]);
         });
     break;
     case ‘SIZE‘:
         usort($list, function ($a, $b) {
             if ($a[‘filesize‘] > $b[‘filesize‘]) {
                 return 1;
             } elseif ($a[‘filesize‘] < $b[‘filesize‘]) {
                 return -1;
             }
             return 0;
         });
     break;
     case ‘DATE‘:
         usort($list, function ($a, $b) {
             return strcmp($a[‘datetime‘], $b[‘datetime‘]);
         });
         break;
     }
 }

 echo json_encode(array(
     ‘base_url‘ => $this->filesUrl . ‘?‘,
     ‘file_list‘ => $list
 ));
