Windows iis+php solve large file upload 500 wrong problem

Linux changed to iis+php, upload more than 2M out of 500 wrong, changed the php.ini in the upload_max_filesize also not, and finally resolved as follows:

First step: Modify the php.ini upload size limit

(for example, above 500M files of the size)
Look for the following options and modify
File_uploads = on; open File upload option
upload_max_filesize = 500M; upload file limit
If you want to upload a larger file, only the above two is not enough, you must increase the server cache limit, the maximum execution time of the script is longer, add the following content, PHP upload is no problem
Post_max_size = 500M;p ost Upper
max_execution_time = 1800; Maximum execution time of each script, in seconds script maximum execution times
max_input_time = 1800; Maximum amount of time each script may spend parsing request data
Memory_limit = 128M; Maximum amount of memories a script may consume (128MB) memory limit

Step Two: Then modify the upload limit for IIS

1. Open Internet Information Services (IIS) Manager;
2, close the IIS service;
3. Double-click on "Your site" → Double-click on "Request Filter" in the pane of the right pane → "Edit feature settings" in the left-hand panel → Modify the "Maximum allowed content length" under "Request Limit", the default is 30M, arbitrarily change the size, I changed to 300M, click "OK";
4, restart IIS, and then upload a try, 50M, 90M can be.
