Ok, works with the snapshot below (4.3.5RC2 ?)
That was fast help, thanks.

Please try using this CVS snapshot:
http://snaps.php.net/php4-STABLE-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php4-win32-STABLE-latest.zip
Works fine for me with the latest CVS.

Description:
------------
I'm copying one binary file (currently GIF's) to another using fread on
a file or URL opened for binary reading.
The copy created is corrupted and doesn't has the same size as
the source.
The script runs nice under PHP-4.0.6 but fread seems to have
an error in version PHP-4.3.4.
Reproduce code:
---------------
<?php
// copies binary file "$from" to a file given by "$to"
function CopyBin($from,$to) {
if ($from) {
$input = fopen($from, "rb");
$image_data = "";
$totlen=0;
if($input) {
$i=0;
while(!feof($input))
{
$inp = fread($input, 10000);
$len = strlen($inp);
$totlen+= $len;
$i++;
$image_data = $image_data . $inp;
}
}
print ("Read in a Total of: $totlen\n");
fclose($input);
$output = fopen("$to", "wb");
fwrite($output, $image_data);
fclose($output);
}
}
CopyBin("source.gif","copy.gif");
?>
Expected result:
----------------
A copy of the binary file source.gif should be in copy.gif
Actual result:
--------------
If I diff -a the 2 files it looks like a few "\0" are missing.
