Bug #60391 [Com]: fputcsv() returns NULL if first argument is not resource

Edit report at https://bugs.php.net/bug.php?id=60391&edit=1 ID: 60391 Comment by: me at ktamura dot com Reported by: ninzya at inbox dot lv Summary: fputcsv() returns NULL if first argument is not resource Status: Open Type: Bug Package: Documentation problem Operating System: Windows 7 PHP Version: 5.4.0RC2 Block user comment: N Private report: N New Comment: NULL is returned when zend_parse_parameters returns FAILURE, meaning the types of the parameters didn't match the function signature. This is the behavior for many other buildin functions such as flock, realpath, etc. I don't think this is a bug. Previous Comments: ------------------------------------------------------------------------ [2011-11-26 08:00:46] ninzya at inbox dot lv Description: ------------ PHP documentation on fputcsv() [http://www.php.net/manual/en/function.fputcsv.php] says (quote): "Returns the length of the written string or FALSE on failure". This is not true if fputcsv() gets a non-resource variable as it's first argument. In this case it returns NULL. Test script: --------------- $arg =true; //$arg =false; //$arg =1; //$arg =null; //$arg =array(); //$arg =new stdClass; var_dump( fputcsv( $arg, array( 'x', 'y', 'z'))); Expected result: ---------------- bool(false) Actual result: -------------- NULL ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60391&edit=1
