我有一个继承的项目，它使用代码点火器、prototype.js 和 swfUpload 来管理大型视频文件。我遇到了上传大型视频文件时窒息的问题。

我已成功上传较小的文件（~198mb mpg 文件和 3mb mov 文件），但在调试上传 1.57 GB mov 文件时遇到问题。

在我的本地机器上，上传在约 1 分钟内完成上传，成功返回。但是，当我转到文件应该存在的上传文件夹（以及成功上传较小文件的位置）时，它就丢失了。

我的错误日志中没有错误。

在我的 .htaccess 文件中，我正在设置：

php_value upload_max_filesize 6143M  
php_value post_max_size 6143M

我通过调用 ini_get() 确认这是有效的

这是我的 SWFUpload 对象：

swfu = new SWFUpload({
   debug: true,
   upload_url: '" . BASE_URL . "/content_management/ajax_asset_upload_files',
   flash_url: '" . BASE_URL . "/js/swfupload/Flash/swfupload.swf',

   post_params: {'PHPSESSID' : '" . $this->session->userdata('session_id') . "'},
   file_size_limit : '10000 MB',
   file_types : '*.*',
   file_types_description : 'All Files',
   file_upload_limit : 100,
   file_queue_limit : 0,
   custom_settings : {
      progressTarget : 'fsUploadProgress'
   },

   // Button settings
   button_image_url: '" . BASE_URL . "/images/buttons/btn_select_file.gif',
   button_width: '105',
   button_window_mode: 'transparent',
   button_height: '20',
   button_placeholder_id: 'spanButtonPlaceHolder',
   button_disabled: true,
   button_cursor: SWFUpload.CURSOR.HAND,
   button_action: SWFUpload.BUTTON_ACTION.SELECT_FILE,

   // The event handler functions are defined in handlers.js
   file_queued_handler : fileQueued,
   file_queue_error_handler : fileQueueError,
   file_dialog_complete_handler : fileDialogComplete,
   upload_start_handler : uploadStart,
   upload_progress_handler : uploadProgress,
   upload_error_handler : uploadError,
   upload_success_handler : assetUploadSuccess,
   upload_complete_handler : uploadComplete,
   queue_complete_handler : queueComplete // Queue plugin event
});

和调试输出：

您的主机可能已禁用您对 set_time_limit(0) 等 php 变量进行 ini_set 以增加最大执行时间的功能，在这种情况下，它将使用 Apache 在 httpd.conf 中的“超时”，默认为 60 秒。还设置FcgidMaxRequestLen，即最大请求长度（以字节为单位）。

在 php 中，还要检查：memory_limit

为了帮助您调试，还可以尝试： ini_set('display_errors','On'); 错误报告（E_ALL）；

也从您的代码中删除任何 at 符号。例如：@$varname 或 @functionName() @ 告诉 PHP 隐藏正在发生的任何错误。

可能是您的 error_reporting 级别设置得太低，因此实际上存在错误，但您没有看到它。以上应该解决这个问题。
