Previous Comments: ------------------------------------------------------------------------ [2019-12-12 09:29:44] jeremy dot touati at gmail dot com Note that this doesn't seem related specifically to fgetcsv. It's just that SplFileObject::seek appears to set the file pointer position differently between the first line and the other ones. Example (still valid in PHP 7.4): https://3v4l.org/O89dJ ------------------------------------------------------------------------ [2019-03-20 09:48:36] tomme87 at gmail dot com Still an issue with PHP 7.3 ------------------------------------------------------------------------ [2018-03-29 23:34:41] cmb@php.net Still unresolved: <https://3v4l.org/3Uh2L>. ------------------------------------------------------------------------ [2017-10-28 23:48:06] sylvain dot witmeyer at gmail dot com 9 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(); } } ------------------------------------------------------------------------ [2014-01-12 11:50:26] asylow at free dot fr If 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" } Second ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
