Can File Uploads Time Out in PHP

Can file uploads time out in PHP?

You need a proper value for the following php.ini settings:

1. max_input_time (not max_execution_time!)
2. upload_max_filesize
3. post_max_size

and maybe

4. memory_limit

How do I prevent a Request Timeout when uploading a file in PHP?

I did some more tests and I cannot upload files over 200kb on any site.

It seems that it may have something to do with my OS (Windows 7 RC2). My girlfriend is on Vista and it works without a problem and I have an XP virtual machine installed which also works.

Request timing out when trying to upload file

Please Update your Max Execution Time in your php.ini file, also PHP server can cause issue's with post requests try switch to apache or xamp server. For more info: https://laracasts.com/discuss/channels/code-review/file-upload-using-guzzle-client
