I dug into this a bit more, Sean, thanks to your
inspiration.
The problem is one of false expectations. Doing this in my
editor:
1
2
3
4
5
<-- Cursor now here.
produces an array which looks like this:
Array ( [0] => 1 [1] => 2 [2] => 3 [3] => 4 [4] => 5 )
In other words, there are SIX lines on the editor but only
FIVE in reality and thus in the array.
A closer look at the hex dump shows:
31 0d 0a
32 0d 0a
33 0d 0a
34 0d 0a
35 0d 0a
In other words, the newline characters are doing what
they're supposed to--throwing the cursor to the next
line--but they are DELUDING THE POOR USER (me, in this case)
into believing he has actually created a blank line.
This is OK for programmers, but no good for users.
If a user is typing a file and wants a blank line at the
end, he/she is obligated not just to press ENTER once and
place the cursor on the new line--which would make sense
from a user perspective--but to press ENTER twice. No good.
A blank line should be a blank line.
Since I'm coding to call include files, I'd say the
reasonable user expectation is to place what LOOKS like a
blank line at the end of a file, and have it show up as a
blank line when the file is read in.
file() did not allow this as I was using it, but for some
reason--I am not sure why yet--this did:
function fileget($filename)
{
$fd = fopen ($filename, "r");
while (!feof ($fd))
{
$buffer = fgets($fd, 4096);
$lines[] = $buffer;
}
fclose ($fd);
return $lines;
}
Knowing what I now know, I think I could now make the file()
function work, but I'm not sure I wish to fix something that
isn't broken.
Thanks for the feedback.
