Question: I'm trying to upload a file larger than 2GB to a local PHP 5.3.4 server. I've set the following server variables:

```none
memory_limit = -1
post_max_size = 9G
upload_max_filesize = 5G

```

However, in the error\_log I found:

> 
> PHP Warning: POST Content-Length of 2120909412 bytes exceeds the limit of 1073741824 bytes in Unknown on line 0
> 
> 
> 

Can anyone tell me why this keeps failing please?

Answer: 
As phliKtid mentioned, this is a limitation with the PHP framework. Save for editing the source code as mentioned in the [bug report](https://bugs.php.net/bug.php?id=44522) phliKtid linked, there is a workaround that involves setting the `upload_max_filesize` to 0 in the php.ini file.

```
; Maximum allowed size for uploaded files.
; http://php.net/upload-max-filesize
upload_max_filesize = 0

```

By doing this, PHP will not crash when trying to convert "5G" into a 32-bit integer and you will be able to upload files as big as you allow with the "post\_max\_size" variable.
We've had the same problem: uploads stopped at 2GB.

Under SLES (SUSE Linux Enterprise Server) 11 SP 2, php53 was the problem.

Then we added a new repository that has php54:
<http://download.opensuse.org/repositories/server:/php/SLE_11_SP2/>

and upgraded to that, we now can upload 5GB :-)
