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
)

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 888888888888888If think the cases above (not using seek) are related to this bug PHP 5.4.7 Case 1 is Wrong ----- $file = new SplFileObject('file.csv', 'r'); echo $file->current(); var_dump($file->fgetcsv()); echo $file->current(); var_dump($file->fgetcsv()); ----- Result : First array(1) { [0]=> string(6) "Second" } Second array(1) { [0]=> string(5) "Third" } Case 2 is OK ----- $file = new SplFileObject('file.csv', 'r'); var_dump($file->fgetcsv()); echo $file->current(); var_dump($file->fgetcsv()); echo $file->current(); ----- Result : array(1) { [0]=> string(5) "First" } First array(1) { [0]=> string(6) "Second" } Second9 years later this bug isn't solved so here is a snippet to achieve the same function readBigCsv($path, $skip=1) { $file = new \SplFileObject($path, 'r'); $file->setFlags(\SplFileObject::READ_CSV); $file->seek($skip); while (!$file->eof()){ yield $file->current(); $file->next(); } }
