New Comment:
It's due the check in spl_filesystem_file_read(): "long line_add =
(intern->u.file.current_line || intern->u.file.current_zval) ? 1 : 0;"
I don't know the reason of this checking. Etienne?

I have the same issue w/ 5.2.6 when writing.
<?php
$fobject = new SplFileObject('/tmp/test', 'w');
$fobject->fwrite("111111111111111\n");
$fobject->fwrite("222222222222222\n");
$fobject->fwrite("333333333333333\n");
$fobject->fwrite("444444444444444\n");
$fobject->seek(2);
$fobject->fwrite("555555555555555\n");
$fobject->fwrite("666666666666666\n");
$fobject->fwrite("777777777777777\n");
$fobject->fwrite("888888888888888\n");
foreach(new SplFileObject('/tmp/test', 'r') as $line)
{
echo $line;
}
?>
Expected result:
----------------
111111111111111
222222222222222
555555555555555
666666666666666
777777777777777
888888888888888
Actual result:
--------------
555555555555555
666666666666666
777777777777777
888888888888888

Description:
------------
Using fgetcsv() after seek()-ing to a non-zero position returns the
contents of wrong line - off by one.
Note that seek(0) works as expected. Also, using current() instead of
fgetcsv() gives the correct line.
Source file (5 lines)
first,line
second,line
third,line
fourth,line
fifth,line
Reproduce code:
---------------
<?php
$file = new SplFileObject('lines.csv');
$file->seek(1);
print_r($file->fgetcsv());
Expected result:
----------------
Array
(
[0] => second
[1] => line
)
Actual result:
--------------
Array
(
[0] => third
[1] => line
)
