Can file uploads time out in PHP?

Hi im quite new to PHP, i have created a form for very large csv files to be uploaded to my server. Some one mentioned to me that the browser can time out due to the uploading file being to big, is this true? and if so, can it be prevented?

Thanks for your help!

For large or multiple files, or users on slower connections, the default of 60 seconds may be exceeded

A good way to work around the poor handling of large file uploads in php, is to use an uploader like JUpload which will split the file into chunks before sending them.

  • The PHP documentation for max_input_time says: "It is measured from the moment of receiving all data on the server to the start of script execution." So why would the file size make a difference? All the data have been received before this timer starts.
  • After testing I confirm that max_input_time seems to have no effect on this issue.
  • I have faced similar issue. When I used to upload file from desktop, it was working fine. But if the same page is used to upload same image from mobile, it used to fail. The error reported on server was due to max file size. Actually, the issue was due to more time taken for image uploading from mobile causing the timeout. After increasing MAX_INPUT_TIME, the issue got resolved.
  • i have no idea where abouts to even go to edit the apache settings :(
  • Ask your provider if these settings are proper to upload large files.
  • To my knowing there's no such directive in PHP - time_limit. set_time_limit() sets max_execution_time.
  • brilliant, thanks for that! i didnt even know about post_max_size or upload_max_file_size! very much apreciated
  • set_time_limit affects the same setting as max_execution_time in php.ini. The doc says "The maximum execution time is not affected by system calls, stream operations etc." Does the file upload count as a "stream operation"? If so, then it appears that this setting won't help.
  • Isn't this the same as vartec's answer?
