$_FILES Empty - Tearing my hair out

Question

Had a form working fine (and still is) but files over a certain size just fail on an empty $_FILES.

I can upload 10Mb files, 60Mb and even 101MB but the file I really want to upload is 120MB and the upload just fails with an empty $_FILES.

The php.ini are set:
file_uploads = On
post_max_size = 750M
upload_max_filesize = 500M
max_execution_time = 500
include_path = .:/usr/local/lib/php
auto_prepend_file = config.php

But the largest file just fails. I have read that my /tmp directory might be full but the only /tmp dir is in the same directory as public_html and this dir has not very much in it apart from awstats and webalizer.

Any help?

Answer 1

check this setting max_input_time . it limits the time a script can parse data.

Answer 2

Somebody says that your memory_limit needs to be raised either.

It should be higher than upload_max_filesize .

If your are running suhosin there are also some options: suhosin.memory_limit , suhosin.post.max_value_length

Additionally there is the max_input_time option.

There could also be some proxies like nginx or varnish which prevents uploading such big files.

Finally there is one directive in Apache: LimitRequestBody

And for mod_fastcgi: FcgidMaxRequestLen , FcgidConnectTimeout

You can also try monitoring your upload with APC and some AJAX driven progress bar: http://www.phpriot.com/articles/php-ajax-file-uploads/3

Are u using "MAX_FILE_SIZE" hidden field in the input file upload html form?

If used please check this issue.

Answer 4

Set these in your php.ini:

upload_max_filesize = 10M
post_max_size = 10M

and check

memory_limit  

to be higher than post_max_size
