Seems like the strings returned from fread always have the length "number of characters to
read". Try this on your favourite file:
clearstatcache ();
$FileHandle = fopen ($FileNameAndPath, "rb");
$b = 0;
while ($Block = fread ($FileHandle, 8192))
{
$b += strlen ($Block);
}
print "file size: ".filesize ($FileNameAndPath)."<br>";
print "read: $b<br>";
fclose ($FileHandle);
On my W2K the two numbers will differ, the number of bytes read
always being a multiple of 8192. You can also look at the strlen of
each block that is read - you'd expect the last one usually *not* to
have a size of 8192, but it does.
Is this to be considered a bug or a feature?
