Bug description: fgets and fgetc require strlen for lengths read
This is the only quick way I know to show the problem, but various testing
after this reveals that fgetc (and fgets) are the culprits. After you ponder the output, notice
that /tmp/b.gif is signifigantly smaller than a.gif. I hex editor reveals that it is exactly number
of bytes smaller as the number of NULLS encountered.
<?php
$fp=fopen("a.gif","r");
$fp2=fopen("/tmp/b.gif","w");
while(!feof($fp))
{
echo fputs($fp2,fgetc($fp));
echo "<br>";
}
fclose($fp);
fclose($fp2);
?>
