When uploading a large file > 8192K, this problem comes up. 

HTML Page

<form action="testing.php" method="post" enctype="multipart/form-data">
<input type=File name="file_attachment" size=20 value="">
</form>

Testing.php

The variable of $HTTP_POST_FILES["file_attachment"]["size"] will equal 8192K if the uploaded file is greater than 8192K, however the file is say 4000K, then the variable $HTTP_POST_FILES["file_attachment"]["size"] will be equal to 4000K. 

We have made the necessary adjustments to php.ini. 

post_max_size = "14M"
upload_max_filesize = "12M"

We have increased the memory limit to "16M". 

Everything is working fine, except when the file size is greater than 8192K

Thanks, 
Jason.

And are you sure that php.ini is really used by PHP?
(check those values from phpinfo() output)

We will do a phpinfo(); on the very receiving script. 

But a phpinfo(); does show the new values of max_post_size, etc. 

Secondly, before the increased these values in php.ini, the script would not work and it would generate a file of 0 bytes. 

Thanks, 
Jason.

Please try the snapshot..I can not reproduce this.

I've isolated the whole situation and I couldn't replicate the problem. 

However, I've found that it's because the filesize is stored to the mysql database and the field is mediumint(9), and when I increased it to BigInt(12), it started working....This is perhaps weird of Mysql....

Sorry to have bothered you. We've got the problem isolated. 

thanks for your time, I hope that we may be able to contribute something to PHP development one day. 

thanks, 
Jason.
