I'm having a problem with upload of binary files (tipically image/jpeg, image/pjpeg).

The problem seems to happen with files bigger than 20k.  Infact it doesn't happen with tiny files like 5-10-15k.

I've done a class to handle file uploads, and it worked fine with previous version of PHP (4.0.6).  I tested also against Linux version (still 4.0.6) and it works fine.

The class simply handle $HTTP_POST_FILES[$fieldname]['tmp_name'] and does a copy($tempName,$filename).

Using $_FILES either doesn't work.

I tested against PHP 4.1.2, PHP 4.2.0RC1 and RC2 too, but the bug still persists, on Windows 2000 platform.

I cannot verify this, but unless the copy function is broken, the temporary file uploaded to Apache is already corrupt.

Any advice is kindly appreciated.

To help tracing this bug I can give the following additional information:

- Apache version is 1.3.23
- Files are always trunked at offset 0x3E4E (15950), or 0x3E3E (15938).  At this position there is always garbage in the form of 7 numbers bigger than zero, and the rest of bytes always set to zero (example:  08 10 C5 01 80 E0 F3 00 00 00 00 00 ... 00 ... until the end of the file).
