But that wasn't the issue, Sean. The issue is where your 0-3
is in file A and 5-7 in file B. It's the newline AT THE END
of a file which seems to go missing.

The file() function seems to be losing the last newline
character (0a). If your 0-3 were in a file and read by
file(), the line count would be three and not four. (This is
for PHP 4.2.something)

I read in the PHP docs that fgets() is a lot faster. I
experimented with fgets() this morning, and the line count
seems correct for that function.

Unfortunately, that appears to disagree with my results for
file(). It is true for all new line characters except the
last one. In other words

1 line a
2 line b
3 line c
4 <-- new line only
5 <-- new line only
6 <-- new line only

will return FIVE from file() with count().

fgets() seems to return the correct count, SIX, used like
so.

function fileg($filename)
{
$fd = fopen ($filename, "r");
while (!feof ($fd))
{
$buffer = fgets($fd, 4096);
$lines[] = $buffer;
}
fclose ($fd);
return $lines;
}
