在 PHP 中创建文件进度条
有谁知道在PHP中创建文件上传进度条的任何方法?我经常听说这是不可能的.
Does anyone know of any methods to create a file upload progress bar in PHP? I have often heard that it's impossible.
我有一个想法，但不确定它是否可行:正常上传文件，而是提交到 iframe.提交后，将文件信息(大小和临时位置)存储在会话中.同时，每隔 10 秒启动一次 AJAX 调用，以检查文件的大小与会话中存储的大小相比.这会将大小返回给 AJAX，然后会调整进度条的大小，并可能向用户显示上传的大小.
I have one idea, but not sure if it would work: have a normal file upload, but instead submit to an iframe. When this is submitted, store the file information (size and temp location) in the session. At the same time, start an AJAX call to every say 10 seconds to check the size of the file compared to the size stored in the session. This would return the size to the AJAX and then a progress bar would be sized and maybe display the uploaded size to the user.
想法?
