Summary: First call to fgets in SplFileObject doesn't
increase file pointer position
Status: Not a bug
Type: Bug
Package: SPL related
Operating System: Debian squeeze
PHP Version: 5.3.10

Ok, I see, thank you.
I think my confusion arose because fgets() reads next line from the file, but
when no line has been read, fgets then reads current line, which is line 0. If
when no line has been read we should consider we are somehow before line 0,
then calling key() before reading any line maybe should return something
different than 0, maybe -1 or false.

This seems correct. The first line is line 0, not 1. The error is that you're
calling key() before the first line is read. You should do it after (or just
use a foreach loop).

Description:
------------
Calling key() method in a new SplFileObject gives 0. This is the expected
result.
If you call now fgets() method and again key() method it gives again 0 as a
result. I think this is not the expected behavior.
Subsequent calls to fgets() followed by key() method increases the result by 1
(1, 2, 3...). This is again the expected result.
The behavior is the same with SplFileObject::READ_AHEAD flag.

Consider following text file, test.txt for the Test Script:
1
2
3
Test script:
---------------
<?php
$file = new SplFileObject('test.txt', 'r');
var_dump($file->key());
$line = $file->fgets();
var_dump($file->key());
$line = $file->fgets();
var_dump($file->key());
$line = $file->fgets();
var_dump($file->key());
Expected result:
----------------
int(0) int(1) int(2) int(3)
Actual result:
--------------
int(0) int(0) int(1) int(2)
