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: ninzya at inbox dot lv 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: Documentation does not cover the case you have described: "Returns the length of the written string or FALSE on failure" does not mean "NULL is returned when zend_parse_parameters returns FAILURE, meaning the types of the parameters didn't match the function signature". So from my point of view the problem is either in the code or in the documentation. Previous Comments: ------------------------------------------------------------------------ [2011-12-03 03:08:39] me at ktamura dot com 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. ------------------------------------------------------------------------ [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
