I have a SQL DB with GIF data field. f.ex there are 2*27006 bytes in there (hex strings). I can retrieve them without any problems but when I do

  $fp = fopen($fn, 'wb');
  $Bin = ConvertToBinary($GIFString);
  $BlockLength=strlen($Bin);
  set_file_buffer($fp, 0);
  fwrite($fp,$Bin);  
  fclose($fp);

$GIFString has the correct size of 2*27006,
$Bin has the correct binary size of 27006.

But the file has the size of 27176 bytes. I have no idea where the addiotnal 170 bytes are coming from (doesn't help when add the $BlockLength to fwrite). After 0x363 there is a 1 byte shift etc...

regards
Jay

Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP -- 
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
